This lemon blueberry cake is like no other cake you have tasted. The lemon cake has a soft, velvety and fluffy texture and beautiful natural lemon flavor which is balanced out by those sweet blueberries. Smooth and tangy classic cream cheese frosting that is just firm enough to frost a cake but not too sweet makes this one of my favorite summer cake flavors. 

lemon blueberry cake

My husband has always loved my lemon cake and for years it was our most popular wedding cake flavor after vanilla cake. Recently I have fallen in love with using buttermilk in my cake recipes whenever possible. So I have updated my beloved lemon cake recipe to use buttermilk and then tweaked it again to make a truly delicious lemon blueberry cake! 

I thoroughly enjoyed taste testing this cake. Not gonna lie. 

Blueberry lemon cake ingredients

lemon blueberry cake ingredients This is the BEST lemon blueberry cake recipe! The secrets to this fluffy, soft cake is using cake flour (low-protein flour), buttermilk and the reverse creaming method. 

Do not fall for the “just add cornstarch to regular flour” trick. It does not work for this recipe. Your cake will look and taste like cornbread. 

Pro-tip – If you’re in the UK search for Shipton mills soft cake and pastry flour or flour that has a protein level of 9% or less. 

Blueberry lemon cake step-by-step

Step 1 – Measure out your buttermilk. Take out 4 ounces and place it into a separate measuring container. Add in the oil. If you double this recipe, remember to double this amount as well.

Step 2 – To the remaining milk, add the eggs, lemon extract, lemon zest, and lemon juice. Whisk lightly to break up the eggs.

Step 3 – Add your flour, sugar, baking soda, baking powder and salt into the bowl of your stand mixer with the paddle attachment attached.

Step 4 – Add in your softened butter in chunks while mixing on low. Mix everything until it looks like coarse sand.

Step 5 – Now add in the milk/oil mixture all at once and bump up the speed to 4 and mix for two full minutes to develop the cakes structure. The batter will be light, white and not curdled looking or broken.

Step 6 – Now add 1/3 of your milk/egg mixture while mixing on low. Let it fully mix in then add in half of the rest of the liquid. Let it mix in then add in the final amount of liquid. Mix until just incorporated.

Step 7 – Divide the batter into two pans prepared with cake goop or your preferred pan release. For added insurance, you can put parchment paper into the bottom of the pan. 

Step 8 – How to keep blueberries from sinking

It wasn’t that hard to get the lemon cake to a place where I was happy with it but the blueberries were a real problem! They kept sinking to the bottom! To counteract this problem I have a couple of tricks for you to keep those pesky fruits from sinking to the bottom of your cake. 

berries being mixed with flour

  1. Wash your blueberries off and then dust them in flour. The flour coating helps adhere them to the cake batter and keeps them from sinking. If your blueberries are frozen, skip this step
  2. Sprinkle half your blueberries on the top of the cake and don’t mix them in. They sink naturally. 
  3. Now the real trick. After 15 minutes of baking, sprinkle some more blueberries on top of the cake batter. Yes… while it’s baking in the oven. I know it’s crazy but I tried it and it worked!

Step 9 – Bake at 350ºF for 15 minutes then sprinkle the rest of the blueberries on top of the baking cakes. Continue baking for another 10-15 minutes or until a toothpick comes out clean and the center of the cake springs back when you press on it. 

Step 10 – Remove the cakes from the oven and place onto a cooling rack. Let them cool down until the pans are barely warm. Don’t let them get cold or they will stick.

Step 11 – After the cakes are cool, flip them out onto the cooling rack to cool fully. Then I wrap them in plastic wrap, put them in the fridge or freezer for 30 minutes to get the cake to firm up so it’s easier to handle before I frost it.

Step 12 – Frost your cooled cakes with cream cheese frosting, decorate with more blueberries and organic pansies if you like!

I also added some really thinly sliced lemons to the side of my cake and they look really pretty. Make sure you remove the seeds as well.

Classic Cream Cheese Frosting

cream cheese frosting

I’ve actually tried this lemon blueberry cake recipe with a few different frostings like my easy buttercream and stabilized whipped cream.

But I feel like the perfect compliment to this cake is my classic cream cheese frosting. The tart and tangy flavor tastes so amazing with the sweet and sour lemon blueberry combo. It’s a match made in heaven really!

Making this cream cheese frosting is pretty easy. It’s a little more stable than some cream cheese frostings but not as stable as my crusting cream cheese frosting recipe. It’s a balance of the two. 

Step 1 – To make the frosting, place your butter in the bowl of a stand mixer with the whisk attachment (or use a hand-mixer). Cream the butter until smooth and lump-free.

Step 2 – Add in your softened cream cheese in small pieces and combine with the butter.

Step 3 – Then add in your extract and salt and done! So easy!

Make sure you don’t over-mix the cream cheese frosting though, it can separate if you mix for too long. 

Is this lemon blueberry cake recipe good for cupcakes?

Yes! I did a little test batch and made this lemon blueberry cake into cute little cupcakes topped with cream cheese frosting. I filled my cupcake liners half full then sprinkled 3-4 blueberries on top. 

Bake at 350ºF for 18-20 minutes until set. After they are cooled you can frost with cream cheese frosting and top with some fresh blueberries and a lemon slice. 

This recipe made 36 cupcakes.

Can you cover this cake in fondant?

The answer is yes! You can cover this cake in fondant but you don’t want to use cream cheese frosting. Cream cheese frosting doesn’t do well next to fondant, it makes it weep and get soggy. 

You CAN fill a cake with cream cheese frosting with a dam of regular easy buttercream to keep it inside and frosted on the outside. Just remember that cream cheese frosting can be at room temperature for 2-3 hours but has to be refrigerated after that.

Lemon Blueberry Cake Ingredients

  • 8 oz (226 g) buttermilk Or regular milk with 1 Tbsp white vinegar added
  • 3 oz (85 g) vegetable oil
  • 3 (3 ) large eggs
  • 2 Tbsp (2 Tbsp) lemon zest
  • 2 Tbsp (2 Tbsp) fresh lemon juice
  • 2 tsp (2 tsp) lemon extract
  • 14 oz (397 g) cake flour
  • 12 oz (340 g) granulated sugar
  • 1/2 tsp (1/2 tsp) salt
  • 2 tsp (2 tsp) baking powder
  • 1/2 tsp (1/2 tsp) baking soda
  • 8 oz (226 g) unsalted butter
  • 2 Tbsp (2 Tbsp) AP Flour for dusting blueberries
  • 2 cups (296 g) blueberries You can use frozen but don't thaw them

Cream Cheese Frosting

  • 16 oz (453 g) cream cheese room temperature
  • 8 oz (226 g) unsalted butter room temperature
  • 1 tsp (1 tsp) lemon extract
  • 1/2 tsp (1/2 tsp) salt
  • 32 oz (907 g) powdered sugar sifted


  • This is the BEST lemon blueberry cake because I use a scale so it turns out perfectly 🙂 If you convert to cups I cannot guarantee good results. Make sure all your (cold ingredients) butter, eggs, milk are at room temperature or a little warm.

Cake Instructions

  • Heat oven to 350º F/177º C. Prepare two 8" round cake pans with cake goop or another pan release that you prefer.
  • Measure out buttermilk. Place 4 oz in separate measuring cup. Add the oil to the 4oz of buttermilk and set aside.
  • To the remaining milk, add your eggs, lemon extract, lemon juice and lemon zest and gently whisk to combine. Set aside.
  • Place the flour, sugar, baking powder, baking soda, and salt into the bowl of your stand mixer with the paddle attachment.
  • Turn the mixer onto the slowest speed (setting 1 on Kitchen Aid mixers). Slowly add chunks of your softened butter until it is all added then let everything mix until it looks like coarse sand.
  • Add your milk/oil mixture all at once to the dry ingredients and mix on medium (speed 4 on kitchenaid) for 2 full minutes to develop the structure. Don't worry, this will not over-mix the cake.
  • Scrape the bowl. This is an important step. If you skip it, you will have hard lumps of flour and unmixed ingredients in your batter. If you do it later, they will not mix in fully.
  • Slowly add in the rest of your liquid ingredients in 3 parts, stopping to scrape the bowl one more time halfway through. Your batter should be thick and not too runny.
  • Fill your pans 1/2 full with cake batter. Give the pan a little tap on each side to level out the batter and get rid of any air bubbles.
  • Wash your berries (if they are fresh) and toss in flour. If berries are frozen skip washing and just toss in flour. Sprinkle half the blueberries on top of your batter. Do not stir them in.
  • Bake for 15-20 minutes then sprinkle in the second half of your blueberries on top of the cake.
    Bake for another 10-15 minutes then check for doneness. If the cakes are still really jiggly, I add another 5 minutes. I check every 3 minutes after that until I'm close and then it's every 1 min. Cakes are done when a toothpick inserted in the center comes out with a few crumbs. 
  • Remove cakes from the oven and give them a tap on the countertop to release air and prevent too much shrinking. Let them cool on a cooling rack until they are barely warm.
  • After cooling, place the cooling rack on top of the cake, placing one hand on top of the cooling rack and one hand under the pan and flip the pan and the cooling rack over so the pan is now upside down on the cooling rack. Remove the pan carefully. Repeat with the other pan.
  • After the cakes are fully cooled, carefully wrap them in plastic wrap and place them into the freezer or fridge for about 30 minutes to firm up the cakes and make them easier to handle for stacking.
  • After your cakes are chilled, fill them with your cream cheese frosting and frost the outside. I finished my cake with some more fresh blueberries and organic pansies (edible). If you're not familiar with decorating cakes, check out my how to make your first cake blog post!

Cream Cheese Frosting Instructions

  • Place softened butter in the bowl of your stand mixer with paddle attachment and cream on low until smooth
  • Place softened cream cheese in the bowl with butter in small chunks and cream on low until smooth and combined
  • Add in sifted powdered sugar one cup at a time until combined
  • Add your extract and salt and combine until smooth. Don't over-mix or your frosting could separate


  1. Weigh your ingredients to avoid cake failure. Using a kitchen scale for baking is super easy and gives you the best results every single time. 
  2. Make sure all your cold ingredients are room temperature or slightly warm (butter, milk, eggs, to create a cohesive batter. Curdled batter causes cakes to collapse.
  3. No buttermilk? You can make your own buttermilk 
  4. To prevent blueberries from sinking, I wash them (to get them wet) then roll them in flour. Then I add them to the batter halfway through baking
  5. Do not fall for the "just add cornstarch to regular flour" trick. It does not work for this recipe. Your cake will look and taste like cornbread. If you can't find cake flour, use pastry flour which isn't quite as soft as cake flour but it's better than all-purpose flour. 
  6. Make your own pan release (cake goop!) The best pan release ever! 
  7. If you're in the UK search for Shipton mills cake and pastry flour. If you're in another part of the country, search for low protein cake flour.

    Very tasty cake!! Will definitely make again. The mL and ounces to cups conversions were a huge pain. I don’t have a scale and don’t plan on getting one. The store was out of buttermilk so I substituted with regular 2% milk mixed with cream of tartar. The cake was definitely heavier and thinner than I expected it to be. The cream cheese frosting was very tasty- instead of lemon extract I used ~2 tbsp fresh squeezed lemon juice that I had leftover from zesting the lemons for the cake and about a teaspoon of zest. The frosting was a bit heavy for the delicate cake batter so some of the cake started falling apart. Overall the flavor is absolutely fantastic and the end result came out very well. My mom and family loved it for Mother’s day.

    1. Hi There, the reason I use a scale is to prevent mistakes in measuring the ingredients. Your cake was most likely flat because you converted to cups. I understand most people do not want to change how they bake but you should really give it a try sometime. Not only is it easier to use a scale, it prevents problems with recipes not turning out. A simple food scale costs less than $20 and can be found at most grocery stores. I hope you had a great mothers day! https://sugargeekshow.com/news/digital-kitchen-scale/

    The flavor was amazing. We used a buttercream frosting because the kids don’t love cream cheese frosting. I didn’t have a kitchen scale so i think the amount of flour was a little off, but it didn’t matter. Was still very yummy & very pretty!

  3. 5 stars
    Thank you this cake is amazing tastes as good as it looks.

  4. My cakes fell apart as I was trying to turn them out of the pan😭 any idea why? I used non stick butter spray to grease my pan, and waited till my cakes were completely baked. Did I not wait long enough for them to cool? And how can I fix this?

    1. Let them cool in the pan until they are just barely warm, then place a cooling rack on top of the pans and flip them both over so that the cake can easily come out of the pan.

    I butter and flour my cake pans or butter and line bottom with parchment. Old school!

    My son’s girlfriend made this for Mother’s Day. I saw it on FB and sent it to her because she loves everything lemon. It was the first cake that she had ever made from scratch. I am not a big sweets eater, but loved this cake. She couldn’t find cake flour, so she used AP and it the cake was soft, moist, tender and delicious. The frosting, despite having 2 sticks of butter and 2 bricks of cream cheese was light and delicious. She did add a little fresh lemon juice to it to give a little more zing. Yum!!!

    The cake was a hit and it was beautiful! I want to make it again this weekend but I am wondering what would make it moister because it was a little dry to me. With another cake, I make I usually beat the eggs, sugar, and butter for 5 minutes which makes it real moist. What do you suggest I do for your recipe when I do it again? I had to convert the recipe because I do not own a scale and I am out of town anyway, I used 1 C Buttermilk 3/8 C of oil, 4 Eggs, 2 T Lemon Juice, 1 Whole lemon zest, 2 t lemon extract, 2 t B powder, 1/2 t B soda, 1/2 t salt, and 1 stick of butter.
    Please let me know Thank You!

    1. Hi there! Thanks for your feedback. I do say to use a scale in this recipe for the best results. Unfortunately using cups is not very accurate and can cause you to use too much flour which is probably why the cake tasted dry. If you have a chance to get a scale at some point, you should give it a try! Makes a world of difference in the quality of the cake.

    This was hands down the BEST cake I’ve ever made!! I’m no professional by any means and I was able to make this and surprisingly this was the least stressed out I have ever been baking! I did use name brand items such as for the cake flour, butter, and didn’t rush anything. I followed every step by step and I don’t have a scale either but I got creative like using shaker cups for measurements and the cake was AMAZING! Thank you so much for sharing this yummy goodness with everyone! We had it for a Mother’s Day treat and I am making it again for our families Memorial Day get together! Question though, we will have a lot more people there, do you think I could double this recipe and make an 11×15 sheet cake? Just curious your thoughts! Thanks again!!

    1. Thank you so much! I’m so glad you enjoyed the recipe! You should try using a scale! Makes the process even easier and less-stressful. I’ll never go back to using cups 😀 Yes you can definitely double this cake without any problems 🙂

  9. Hi Liz! This is a silly question, but… do the 2 tablespoons of lemon juice have an effect on the leavening of the cake? I love blueberries & I love vanilla buttermilk cake, but I don’t like the taste of lemon! 😭 This cake looks INCREDIBLY moist & I’m curious to try without the flavoring of the lemon (I’m thinking of subbing vanilla extract & vanilla bean, for the lemon extract & zest). I love your other vanilla buttermilk recipes, but I’m so curious to try this one!! Will not adding the lemon juice have an effect on the rising of the cake? Thanks, Liz!

    1. So if I’m understanding correctly, you want a vanilla lemon cake correct? If that is the case you can definitely leave out all the lemon and replace with vanilla. The buttermilk is still acidic enough to react with the baking soda.

    I saw this cake picture in FB and had to make it for Mother’s day!
    It was a big hit !!!
    Colorful and Delicious!

  11. I just bought a scale because I plan on making your cake goop recipe! So excited! Thanks again for sharing this!!

    I have no idea what went wrong. I bake a lot and usually don’t have a problem with my cake structure. They turned out of the pan beautifully but when I tried to move them off the rack, to wrap them in plastic, they started falling apart. I’m almost afraid to try and frost them. What could’ve happened?
    I am hoping they’ll firm up enough in the refrigerator to let me finish this recipe.

    1. It could be they are just a little warm or slightly under-mixed. Try putting the whole cooling rack into the fridge to help them hold their shape but they will stick to the cooling rack as they cool. You can use a knife to slice under the cake and remove it. Not the best way but can help you deal with a crumbly cake.

  13. I don’t yet have a scale, so I went with 3 3/4 c. cake flour and 1 2/3 c. sugar, and it turned out well! The structure was sturdy, and it almost tastes like a delicious muffin cake. Absolutely looking forward to trying it again once I get my hands on a kitchen scale (it’s a little absurd that I don’t have one, considering how many years I’ve been baking 😅). Thanks so much for the detailed instructions!!

  14. Hi! On the powdered sugar, is that a 32 ounce bag sifted or 32 ounces of sifted sugar?

  15. The recipe says 3 eggs but the picture and the video say 4. Not sure which it is.

  16. Wow, this cake looks incredible. To verify, does it need to stay in the fridge then until ready to serve, and go back in immediately after? Can’t wait to make this as soon as we nap some fresh blues!

    1. Hi there, because of fresh fruit, you definitely want to keep this in the fridge. Take it out of the fridge 4 hours before serving so it has time to soften up to room temperature to eat. Cold butter doesn’t taste very good. Store leftovers in the fridge wrapped will in plastic wrap to prevent drying out.

    The cake looks amazing. Will make it for our Memorial Day gathering. I saw an image on Leite’s C. site. It looked as if the cake was baked in pastry liners. Please explain the method to making those small cakes. Thank you.

  18. Hi Liz! First time cake baker here. I don’t have a stand mixer. I have an electric hand mixer. Is there anything I need to be aware of with this difference while making this lemon blueberry buttermilk cake?

    1. I havent ever used a hand mixer for a cake, I have bad tendonitis so I can’t grip the mixer. I would just follow the directions using your hand mixer 🙂

    Good evening Ms. Marek!!!!! You’re absolutely correct. Using a good scale is awesome. When I started culinary, the instructors had us using a good scale. That’s how I got my start and I love it. As for your cake recipe, my husband and had a great outcome the cake color was nice. We’re in the process of frosting it. You’re also right about putting it in the fridge or freezer for a short period. It makes it easier to frost a cake. Once it’s frosted, we just let it come to room temperature and serve it. Thanks for sharing. I will start following your blogs.

  20. Hello, what if I don’t have a paddle brush and unfortunately I can’t find a mixer in the stores, everyone is baking. How do I substitute using my mixer? Thank you
