Carrot Cake Bars

Jump to Recipe Print Recipe

These easy carrot cake bars with cream cheese frosting are simple to decorate, serve and eat. A pecan shortbread crust under this springy cake creates a hybrid cake bar that you can eat with your hand or a fork! This is a great recipe for when you have little time to put together a dessert for a crowd.Carrot cake bar held up by a server

Is it a bar or is it cake? Both! This cake bar will satisfy a carrot cake lover and maybe even convert some carrot cake haters. I love the cute but simple decor covering an amazing flavor of warm spices and flavors in a moist tender cake. This is a good one to add to your Easter recipes!

Carrot Cake Bars Ingredientsbowls of ingredients for carrot cake bars

Carrots are obviously the key to this recipe, but it's important to use good-quality ingredients. If you don't like the stringy texture of graded carrots, you can pulse them in a food processor to break down the shreds for a more consistent cake texture. You can grate your own, or a good cheat is buying shredded carrots from the store.

Oil is the key to moisture in this cake. Many of our cake recipes use butter like the white velvet cake, coconut cake, and even my chunky carrot cake recipe, but oil will keep this cake moist even if it's cold or at room temperature.

Spices enhance the flavor of the carrot, and you can customize the spice combinations to your liking. I kept it simple, but allspice and cloves are good additions to carrot cake as well.

Buttermilk adds a tangy flavor to the cake and it tenderizes the crumb. If you do not have buttermilk you can substitute by adding a teaspoon of lemon juice to a cup of regular milk. Check out my buttermilk substitutes blog post for more recipes.

How to Make Carrot Cake Bars

There are 4 separate components to making these carrot cake bars; the cookie crust, the carrot cake, the cream cheese frosting, and the piped carrot decorations. This cream cheese frosting recipe is made without powdered sugar and has a cheesier flavor and smoother consistency. If you like a sweeter frosting though, try my traditional cream cheese frosting.

Making the Crust

  1. Spray a 9"x13" baking pan with cooking spray and preheat the oven to 350°F and position the rack in the center of the oven. Pro-tip: If you line the pan with parchment paper, leave some overhang and it will be easy to lift the cake out of the pan.Hand spraying a pan with a can of pan release.
  2. Grind the cookies and salt into crumbs in a food processor. Hands adding a bowl of cookies into a food processor
  3. Melt the butter in the microwave and then add it to the crumbs and pulse briefly to combine.Hand adding melted butter into a food processor
  4. Press the crumb mixture evenly into the bottom of the baking pan, then set it aside while you mix the cake. Pressing crust into a baking pan

Making Carrot Cake

  2. Combine the flour, baking powder, baking soda, salt, cinnamon, ginger, and nutmeg in a large bowl and set aside.Glass bowl of dry ingredients for cake
  3. Combine the buttermilk and vanilla extract, and set aside.

Making Cream Cheese Frosting

  1. Make sure the butter and cream cheese are both slightly warm and at the same temperature. If one is colder than the other, they will not mix together properly and create lumps.
  2. Begin mixing the cream cheese in the bowl of a stand mixer with a paddle attachment until it's smooth.adding a bowl of cream cheese to a glass stand mixer bowl
  3. Then, add the butter in chunks and mix until incorporated. Pro-Tip: Using an electric mixer works really well for cream cheese frosting because it emulsifies the butter and cream cheese quickly. Just be careful not to over-mix.adding a bowl of butter to a glass stand mixer bowl
  4. Once the butter is incorporated, add the granulated sugar and vanilla. Continue to mix for 30 seconds to 1 minute until smooth and the sugar is dissolved. Hand pouring a container of sugar into a stand mixer bowl
  5. Cover with plastic wrap until you are ready to frost the cake. Keep the remaining frosting in the refrigerator as cream cheese frosting should not be stored at room temperature for more than 4 hours.

Assembling the Carrot Cake Bars

  1. Once the cake has fully cooled, remove the cake from the pan and place it on a cutting board or the plate you choose to serve it from. The cake can also be left in the cake pan for transporting and serving as well. To remove this cake, loosen the edges of the cake with a knife. Place a board on top of the cake pan, then flip it out and remove the pan.inverting a cake out of a rectangular pan onto a cutting board
  2. Then, place the serving board or plate on the cake (bottom side up) and flip it back over so the top of the cake is upright again.Rectangular carrot cake on a wooden cutting board
  3. Spread an even layer of cream cheese frosting on top of the moist carrot cake and create some pretty rustic swooshes with an offset spatula. Carrot cake frosted in cream cheese frosting

FAQ

What's the difference between carrot cake bars and a carrot sheet cake?

If you love carrot cake you will love carrot cake bars! It's basically the same thing except this cake holds together well and has a crunchy bottom crust which allows it to be handled without a plate and a fork. However, it still has the signature cream cheese frosting for the classic carrot flavor

Do I have to have a crust?

No, you can omit the crust part altogether. Just make sure the bottom of the prepared baking dish is well coated with cake goop to avoid sticking. This easy carrot cake recipe can easily be baked in a square pan or round pans for cake layers as well.

Do I have to use shredded carrots?

Similar to coconut, some people don't enjoy the texture of shredded carrots in their cake. You can take them a step further and pulse them in a food processor to break down the shreds for a more consistent cake texture. If the shredding of the carrots is holding you back, most grocery store produce sections will have bags of freshly grated carrots.

What can I substitute for buttermilk?

If you don't have buttermilk you can substitute the same amount of sour cream for this recipe, or add a tablespoon of lemon juice to regular milk. Check out my buttermilk substitute blog post for more info.

  5. Bring all your ingredients to room temperature or even a little warm to ensure your batter does not break or curdle. 
  6. Use a scale to weigh your ingredients (including liquids) unless otherwise instructed (Tablespoons, teaspoons, pinch etc). Metric measurements are available in the recipe card. Scaled ingredients are much more accurate than using cups and help ensure the success of your recipe.
