People sometimes ask what is the difference between sheet cake and regular cake.
Technically, sheet cake is a kind of cake rather than something different.
That is, sheet cake is a cake that is simply baked in a pan that is not round like a 'normal' cake usually is baked in.
Here is what a sheet cake actually is.
A sheet cake is a cake that is baked in a sheet cake pan.
These cakes may be a bit more dense than a round cake because of the sheet cake pans that the cakes are baked in.

About this recipe for sheet cake.
This is a simple cake recipe that is made in a sheet cake pan.
Use a rimmed sheet cake pan that is at least two inches tall (9 X 13 works well) to get a good sized piece of cake rather than a bar sized serving.
This cake is also keto, low carbohydrate and gluten free diet friendly.
We are using coconut flour and almond flour rather than all purpose flour. Please make sure that you are using the designated amount of each of these flours as indicated in the recipe for best results.
Ingredients needed to make sugar free sheet cake.
- Almond Flour- 2 ½ cups.
- Coconut Flour- ¼ cup.
- Baking powder- 2 teaspoons.
- Butter- ½ cup, melted and then allowed to cool.
- Sugar Alternative- ⅔ cup. I like erythritol for this recipe. Use a sugar alternative that is granular, measures like erythritol, and that can be baked with.
- Eggs- 5. Two of the eggs should be separated. You can place the yolks from the two separated eggs with the three other full eggs for this recipe. You will need the egg whites for this recipe too.
- Apple Cider Vinegar- 1 teaspoon.
- Vanilla Extract- 2 teaspoons.
- Lemon Juice- 2 tablespoons.
- Lemon Zest- 2 teaspoons.
- Blueberries- 1 cup. Plus additional as desired for topping. The blueberries should be at room temperature.
- For the optional frosting, cream cheese (1 cup, soft), Butter (½ cup, soft), Sugar Alternative (1 tablespoon or to taste). You can also add ½ teaspoon of extract or as desired for flavor.
How to make Sugar Free Blueberry Sheet Cake
- Preheat your oven to 350 and prepare your rimmed sheet pan for nonstick. I like parchment paper but, greasing with margarine etc. works fine in this recipe too.
- In a medium bowl, use a whisk or a fork to mix together the almond flour, coconut flour and the baking powder. Set this bowl aside.
- Next, in a mixing bowl, beat together the butter and the sugar alternative until combined. Then beat in three eggs and two yolks (save the two whites for later use in this recipe) along with the the apple cider vinegar, vanilla extract, lemon zest, and lemon juice. Lastly, stir in the dry ingredients from the medium bowl until just combined.
- For this next step, we need to beat the egg whites until firm peaks develop. I suggest that you use clean mixer attachments to do so. What I do is use a stand mixer for the first part of this recipe and then a hand mixer for the egg whites. If you are able to do so, this will make your life a bit easier with this recipe.
- Now, we will first use a rubber spatula to fold in the blueberries to the batter. Then we will gently fold in the peaked egg whites over the blueberries and batter. Once this is done your can transfer the cake batter to your prepped baking pan.
- Bake for 20-25 minutes or until the center of the cake is set and a toothpick comes out clean. Allow the cake to cool before frosting it. For the frosting, simple combine the listed frosting ingredient. Refrigerate the cake for at least an hour before serving to allow for the frosting to set.
