The death by chocolate cake is the perfect cake for the ultimate chocolate lover. This features three layers of ultra decadent, moist cake with big chocolate chunks. Then it's slathered with light and fluffy easy chocolate buttercream and a chocolate ganache drip. It's chocolate heaven (Get it? Because you died haha) in every bite!
This cake gets its amazing texture and a big flavor boost from dark, flavorful Guinness stout beer, Dutch-processed cocoa powder, espresso powder, big chocolate chunks, and even a little mayonnaise! This is hands down, the MOST amazing chocolate cake I've ever personally tasted. It's so moist I'd almost say it's on the verge of being too moist. Is that a thing? It's so full of chocolate flavor it's practically fudge.
When I first made this cake, halfway through I thought, "there is no way I'm making this cake again, it's taking way too long!" But then... I tasted it. And I died. I died a delicious chocolate death and then I was re-incarnated thankfully so I could go in for a second bite.
INGREDIENTS
Before you start this recipe, I highly suggest you go through the ingredients to make sure you have everything on hand. There are some ingredients you might not have ready in your pantry.
I frequently get asked about substitutions so I will list them here.
Dark Beer - No this will not make your cake alcoholic. The alcohol cooks out but the fizzy nature of the beer and its deep dark flavor adds a TON of flavor to the chocolate. You can replace the beer with room-temperature coffee or water. If you use coffee, leave out the espresso powder. I prefer using Guinness beer because it already kinda tastes like chocolate!
Espresso powder - Again, the espresso powder will not make your cake taste like coffee, it just boosts the flavor of the chocolate and it's amazing! If you don't have espresso powder, you can also use an instant coffee mix. If you can't find either or you don't want to use it, just leave it out but trust me, the cake will not be as good without it!
Dutch-process cocoa powder - Natural cocoa powder like Hershey's is alkaline meaning it needs something like baking soda to make the cake rise. Baking soda can leave an aftertaste in your cake if you use too much. By using the dutch process cocoa powder, we can use baking powder to make our cake rise plus a little baking soda for flavor. If all you have is Hershey's replace half the baking powder with baking soda.
Mayonnaise - I know it might sound odd to be adding mayo to your chocolate cake but trust me if you want moist, mayo is the way to go! Mayonnaise is made from eggs and oil. Eggs and oil = moisture! If you don't want to use mayonnaise or you don't have any, you can replace it with oil but only use half as much as the mayo by weight, or your cake will be too oily.
STEP-BY-STEP INSTRUCTIONS
BEFORE YOU START – Bring your butter, Guinness, eggs, and mayonnaise to room temperature and prepare the rest of your ingredients. Check out my blog post on room temperature ingredient hacks for more info.
For best results, use a food scale to weigh your ingredients. Converting this recipe to cups could lead to failure. Read my blog post on how to use a scale for more information.
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.
Step 1– Preheat your oven to 335º F/168º C. Prepare your cake pans with cake goop or another preferred pan release. I used three 8" round cake pans but you can adapt this recipe to any size pan by using my cake batter calculator right above the recipe card at the bottom of this blog post. Optional: Line the bottom of the pan with parchment paper to prevent sticking from the chocolate chips.
Step 2 – In a large measuring cup combine the beer, espresso powder, and vanilla. Whisk it all together.
Step 3 – In a large bowl, sift together the cake flour, cocoa powder, salt, baking powder, and baking soda.
Step 4 – Place softened butter in the bowl of a stand mixer with the paddle attachment. Cream on medium until smooth and shiny. About 30 seconds.
Step 5 – With the mixer on low, gradually sprinkle in the sugar. Mix on medium-high until mixture is fluffy and almost white. About 3-5 minutes.
Step 6 – Reduce the speed back to low. Add your eggs one at a time. Let the egg incorporate fully before adding in the next egg to avoid breaking your batter.
Step 8 – Next add in your room temp mayonnaise and mix until combined.
Pro-tip - If your batter is broken (curdled looking) your cake will not rise properly and you will get an un-cooked gummy layer at the bottom of your cake. So it's very important to make sure your eggs, mayo, beer and butter are all room temperature or even a tad warm so they mix together properly.
Step 9 – With the mixer on low, add in ⅓ of your dry ingredients and mix until almost combined. Add in ⅓ of your liquid ingredients. Scrape the bowl. Repeat the process two more times until everything is combined. 
Step 10 – Mix in your chocolate chips or chopped chocolate at the end. These chocolate chunks take the death by chocolate cake over the top and make it ultra chocolate-y (is that a word?)
Pro-tip –Using finely chopped chocolate or mini chocolate chips is best, regular chocolate chips are too big and will sink to the bottom of the pan.
Step 11 - Divide your cake batter into your prepared pans (I like using homemade pan release, cake goop). I'm using three 8"x2" cake pans and I used a scale to make sure each pan had the same amount of batter in them so I get even layers. Totally optional haha!
Step 12 – Bake at 335º F/168º C for 40-45 minutes (baking times will vary depending on the size of the pan you use) until a toothpick comes out cleanly but with a few sticky crumbs. Don't overbake.
Step 13 – Let your cakes cool in the pan for 10-15 minutes. Flip the pans out onto a wire rack and cool fully.
Pro-tip - To easily remove cakes from the pan, place the cooling rack on top of the barely warm cake pan. Hold the cake pan and the cooling rack together with your hands, one on top, one on the bottom. Flip the cake pan and the cooling rack over and set them both down so the cake pan is now on top of the cooling rack. Lift the pan off.
Step 13 – To cool completely, gently wrap the cakes in plastic wrap and chill until they are firm enough to handle. You can flash chill them in the freezer for an hour if you need to cool them quickly.
EASY CHOCOLATE BUTTERCREAM STEP-BY-STEP
I love pairing this cake with easy chocolate buttercream, Swiss meringue buttercream, or chocolate cream cheese frosting. Just add ¼ cup sifted powdered sugar or ¼ chocolate ganache (you can use the leftovers from your drip) and add it to my regular cream cheese frosting recipe.
Step 1 - Add the pasteurized egg whites and powdered sugar into the bowl of your stand mixer. Mix on low for 30 seconds to combine.
Step 2 - Add in your sifted cocoa powder, salt, and vanilla extract. Then bump the speed up to high.
Step 3 - Start adding in your softened butter in small-ish chunks. About the size of a large marshmallow until you have added it all.
Step 4 - Continue letting your buttercream whip on high until it is light and creamy and tastes like chocolate ice cream. This can take 10-15 minutes or more depending on the strength of your mixer or if your butter is cold. If it still tastes like butter, keep whipping!
Pro-tip - If your butter is not mixing in, it might be too cold. Take out 1 cup of your buttercream mixture and microwave it for 15 - 30 seconds until its JUST melted. Not hot! Pour the mixture back into your mixing buttercream and it will help it come together.
GANACHE DRIP STEP BY STEP
Step 1 - Microwave your chocolate for 30 seconds to warm it up
Step 2 - Heat your heavy cream until it just begins to simmer. Do not boil your cream or it will cause your drip to split. Learn more about making the perfect ganache drip here.
Step 3 - Let your ganache cool to 90ºF before dripping. I usually make my drip right before I start frosting my cake. By the time I have done the crumb coat and the final coat of buttercream, the drip is ready to use.
DEATH BY CHOCOLATE CAKE ASSEMBLY
For more information on how to make your first cake step by step, check out my how to make your first cake tutorial.
Step 1 - After your cakes have cooled and chilled so they are easier to handle, cut off the domes with a serrated knife to level them.
Step 2 - Place your first layer of cake on your cake board or on top of your cake platter and fill it with chocolate frosting. I like to go for about ¼" of buttercream. Try and keep the frosting level with an offset spatula. Repeat with the next layer.
Step 3 - Cover the entire cake in a thin coat of buttercream. This is called the crumb coat and will lock in those crumbs! Then freeze the cake for 20-30 minutes to set the buttercream.
Step 4 - Apply the final layer of buttercream and smooth with a bench scraper or your offset spatula. Level off the top with your offset spatula.
Step 5 - Send the cake back to the fridge for 15 minutes before you do the drip.
Step 6 - Place your cooled ganache into a piping bag and snip off the tip. Don't make the hole too big. Drip one drip on the side of the chilled cake to make sure it doesn't drip too far. If it does, it might be too hot and need to cool before you do the drip.
Step 7 - I used my leftover buttercream and ganache to make some swirls for the top of the cake with another piping bag and a 1M piping tip.
Just look at that gorgeous chocolate dessert! If you're going to experience death by chocolate, this is the way to do it! Even though the drip and the swirls are super simple, they look truly gorgeous!
Pro-Tip - I always keep my frosted cakes in the fridge. The frosting acts as a barrier and keeps the cake fresh but NEVER serve a cold cake. Cold cakes taste very dry because the butter is cold. Always take your cakes out of the fridge a few hours before you serve them. I've even gone as far as microwaving my cake slice for 10 seconds if it's too cold.
FAQ
For this recipe yes. Cake flour is a low-protein flour that results in less gluten development during the reverse creaming stage. You cannot do the flour/cornstarch trick or the cake will get over-mixed and taste like cornbread. If you only have all-purpose flour, try my easy chocolate cake recipe.
I promise your cake will NOT taste like mayo! It adds a lot of moisture to the chocolate cake for that yummy stick to your fork texture. You can also use plain Greek yogurt or sour cream, but the flavor won't be the same.
You can use water or coffee. The Guinness intensifies that rich chocolate flavor, it doesn't make the cake taste like beer and all the alcohol cooks out.
Espresso powder is commonly used in baking to bring out the chocolate flavor. It is made from coffee beans that have been brewed, dried, and ground into a fine powder. It's much more concentrated than instant coffee but won't add any coffee flavor to your cake.
You can make your own espresso powder, or substitute it with dark roast instant coffee. It won't bring the same rich, roasted flavor, but it will do the trick if you're stuck.
Dutch-processed cocoa powder and natural cocoa powder are not the same. Dutch-processed is treated with an alkali to neutralize its acidity, making it have a stronger flavor and a darker, almost black color. If you can't find Dutched, you can use regular cocoa powder instead.

Would this chocolate cake be good for a blackforest cake? Or could you recommend any of your chocolate cakes to use as base for my blackforest cake please. Thank you.
Elizabeth Marek says
I would use the easy chocolate cake as a base and use whipped cream and cherries to decorate it. Traditional black forest cake also has a simple syrup with kirsch added to it (a type of alcohol).
Anesia Thompson says
Hi Liz
I want to make this cake for a client next week.
I'm wanting to do a two tier, ganache them and cover it in your LMF, will it hold ? Or is the LMF going to be too heavy and collapse the cake?
I love all your recipes and advice. I love how you've been your authentic self since day1 great work!!
Elizabeth Marek says
Yes it will hold! Just chill the cakes until they are easy to handle before stacking 😀 Thats why I love butter cakes!
Peace A says
Best chocolate cake ever! Thanks alot for sharing. I didnt have a good chocolate recipe until I used yours.
Its yummy!!
Christy says
I keep making this cake because people in my house keep asking for it. The absolute best cake ever. We have one person in the house that can't have gluten though. I know doing gluten free will kind of 'ruin' it but do you have any recommendations for substituting guiness? I was hoping maybe I can get semi close by still using the mayo, espresso powder and mini chips. I've made many of your cakes now and you have the absolute best recipes. I love your site, thank you!!!!!!!
Elizabeth Marek says
You can just use water if you want to omit the guinness but it wont have quite as strong of a chocolate flavor. You can also replace the flour with cup 4 cup gluten free mix
Briana says
Hi Liz! For the 3 layer cake you have in the photos, did you adjust your recipe card to 3 layers 8in cake, instead of 2 layers 8in cake? Thanks SO much
Elizabeth Marek says
The recipe is already formulated for three 8" round cake pans
Bonnie Hanson says
I baked this beautiful cake into 3x 8” perfect layers and will be filling it with Nutella Swiss meringue and Ferraro chocolate. This will be the bottom 8 inch tier of my daughter’s wedding cake for the groom, he loves Guinness and chocolate 😊
Lynn B says
Question- my cake came out really really dry. Do you mean to use a 14 ounce can of Guinness or actually 14 ounces of Guinness? A 14.9 ounce can yields 6.9 ounces on a weight scale. A vast difference. Please advise as I am about to waste a whole lot of ingredients for the second time
Elizabeth Marek says
I am not sure how you are getting those numbers. A can of guinness, unopened weighs 16.25 ounces. I opened the can, poured it into a glass container on a scale (zero'd out) and the liquid weighed 14 ounces.
Mary eileen Loscos says
Hello Liz. I really want to try making this cake but I cannot find Guinness or any stout beer in my area. Can I use black beer or dark lager beer instead?
Elizabeth Marek says
I assume so, I'm not sure what they are but I think it would be fine
Nathalie F says
Hello Liz, I really want to try making this cake but I wanted to make a 4" round cake with this recipe. What would you recommend on how to divide the measurement from this recipe?
Thank you! 🙂
Elizabeth Marek says
One 4" round? I'm not sure how you could possibly reduce the ingredients enough to make such a small cake.
Dorothy Asomaning says
This cake is so decadent and absolutely delicious 😍
Mariah says
So first.. this cake is delicious!!!!
I let the cake cool, flipped it out of the pan, the bottom stuck. When i went to flip it a second time to wrap it in cling wrap, it was too soft and fell apart. Am i moving it too quickly?
Elizabeth Marek says
Yes, I would give it a bit more time to cool before flipping. And flip with care. I place the cooling rack on top of the cake pan, then flip both over at the same time. Lift the cake pan off an allow the cake to cool fully before wrapping in plastic wrap (or until its just barely warm)
sheldon crooks says
I am a classically trained pastry chef but worked as a VP in fashion for 17 yrs and although I do cakes on and off its not my main thing. I had a Bat Mitvzah cake this weekend and followed your recipe and it was amazing however it was three tiers covered in fondant that cracked, sagged and shifted the layers bubbling the fondant. Help i would love to pay for a subscription to get help with stacking torting working with fondant and using rods /straws to stack cakes.
Do u think if i paid for a subscription and follow your recipes and advice under your tutelage i would get better as I would like to do this now full time
HELP
Elizabeth Marek says
You don't need a subscription to learn how to stack a cake. I have a free tutorial here. You can use the info for any type of cake, not just a doctored box mix. I also have a video on how to cover a cake in fondant.

yashodhara kulkarni says
Hey I tried this recipe and it is delicious !!! I wish I could post a picture here.
Brian says
Hi Liz! Excellent recipe and instructional video. One question for clarification, if I want to bake this cake like you did in the video in 3 8"x2" pans, do I need to increase the recipe to produce more batter? The reason I ask is that in the video you mention to fill each 8" pan with about 3 1/3 cups batter (10 cups total). However, the recipe as written indicates it will yield only 8 cups batter. Thanks so much.
Elizabeth Marek says
Yes you would increase the amount of batter. You can use the cake batter calculator right above the recipe to calculate how many cups of batter you need.
Brian says
Thank you!
Effie Linara says
I’ve made it and it was absolutely amazing and very delicious. I used chocolate ganache to fill and cover it in order to make a watermelon slice fondant cake. Everyone was amazed by its flavor and taste.
Thank you so much!!!
Love from Greece
Barb Magnuson says
Most amazing cake ever!!! Family and friends cannot stop talking about it! Thank you Liz!
mashael b says
Hello Liz,
You are absolutely my hero, I have learned so much from you.
I have question please. I have made your moist vanilla cake but I Froze it for couple of days before starting to work on it, is that ok? or should i just keep it in the refrigerator?
Does it affect the cake moistness? And for how long can I keep it freezed
Thank You so much!
Sugar Geek Show says
Hi thank you so much! Yes, definitely freeze your cakes. I always wrap them in plastic wrap to keep them from drying out. It's best to only freeze them for about a week or two max.
Touria says
Hi Liz thank you so much for sharing your recipe bit we don’t use alcohol can I switch that to coke or Pepsi?
Is that’s can work?
Sugar Geek Show says
You can use water or coffee instead of beer, but I wouldn't use soda
Stephanie says
Can I make this cake ahead of time?
Sugar Geek Show says
For sure, I wrap my cake layers in plastic wrap and freeze or refrigerate them before stacking. No more than a few days in advance, though. Or you can stack and frost the cake a few days in advance and store it in the fridge.
Daisy says
Hi Liz! Thank you so much for this recipe, I keep watching the video ever since i fell upon it weeks ago and I salivate over it 🙂
I am finally going to make this deadly-cious cake this week but I could only get "Guinness foreign extra stout" and not the "Draught" as I saw that you used in your video. I know that the extra stout is more intense in flavor and so I was wondering if it is still okay to be used to make this cake?
Thanks for your answer.
Elizabeth Marek says
Yes its ok
Deede says
Made it for my adult son's birthday this last October. It really is one of the best chocolate cakes, right up there with Marcel Desaulniers' Death By Chocolate. We finally stopped cutting slices and all 14 of us just ate what was left with our forks.
Mark wilson says
Definitely the best chocolate cake I’ve tasted and the fact I made it myself was a bonus Thankyou liz you have converted a doctored box mix person aha.
Damien says
I made this for my Dad's 70th birthday and eveyone who had some was blown away. My Ganache didnt really work out, but it was still all delish!! time to make more of your recipes!
