What you need to make a chocolate sheet cake.
ย
- Almond flour. This is used instead of all purpose flour in order to keep this recipe keto and gluten free friendly. The almond flour also adds flavor and a bit of protein to this recipe.
- Unsweetened Cocoa Powder. We add this because it ss what makes the chocolaty.
- Baking powder. Used as the leavening agent for the cake.
- Oil. Preferably something neutral such as sunflower or canola oil. This helps keep the cake moist.
- Erythritol. The sugar alternative choice for this cake. Note that this does not measure 1:1 like other alternatives or sugar.
- Apple cider vinegar. This helps with the texture of the cake by aeration.
- Eggs. The eggs help to hold in the moisture of this cake. More importantly, since the flour is gluten free, the eggs help to bind the ingredients together. Three of the eggs will need to be separated.
- Vanilla extract is added to help balance out the flavors.
Ingredients needed for the sugar free butter and cream cheese chocolate frosting.
- Cream Cheese. This should be softened to room temperature.
- Butter. Also softened to room temperature.
- Sugar Free Powdered Sugar. We want this to be light and fluffy so it is recommended that you sift or whisk the the powdered sugar alternative.
- Milk or heavy cream. This is really added as needed for texture. Almond milk can be used as can half and half be used.
- Unsweetened cocoa. This is what makes the frosting a chocolate one. For a more unique flavor you can use Dutch process for the chocolate.
- Vanilla Extract. Again, this is added for flavoring.

How to make chocolate sheet cake.
My sheet cake was made in a rimmed 9 X 13" rimmed baking sheet .
- Start by preheating your oven to 350 and also prepping your baking sheet for nonstick. I like parchment paper for this recipe. Also, if your eggs are not yet separated, also separate your eggs now.
- In a medium bowl, whisk together your almond flour, cocoa powder, and baking powder.
- Now, in a mixing bowl, you can beat together your sugar alternative and oil until creamy. Next, mix in the apple cider vinegar along with the separated egg yolks and the remaining full eggs (that's three egg yolks plus two full eggs).
- Next, add the dry ingredients from your first bowl to the mixing bowl along with the vanilla extract to the mixing bowl and then mix until combined.
- Now for the egg whites, you will also need to use a very clean mixing bowl and very clean whisk attachments. However, you should beat the egg whites until firm peaks are formed. Then, once formed, gently fold the egg whites into the cake batter, however, adding about a third of the whites at a time.
- Next, bake the cake for 15-20 minutes or until toothpick comes out clean. However, you should not overbake this cake. Also, you should also allow the cake to thus fully cool before adding the frosting. Additionally, you can however refrigerate your cake before you serve it to also allow for the frosting to thus set.

Tips for making the best sheet cake.
This recipe calls for erythritol as the sugar alternative. If you decide to use a different alternative to sugar, use one that measures like erythritol (which is not the same as sugar).
More helpful tips for you.
- This recipe uses a simple chocolate flavored frosting that was piped on top of the cake. Feel free to omit the frosting, use the frosting of your choice, or even use a frosting knife rather than a piping bag/
- Almond flour is also used in this recipe. You can use an alternative to almond flour however, make sure that the alternative measures like almond flour and adjust the eggs as needed if there is a binder in the flour.
- My cake uses vanilla extract to help balance the flavor of this cake. You can use another extract, such as a mint extract, instead of or with a portion of that vanilla extract.

How to store sheet cake.
Leftover sheet cake should be covered with plastic wrap or the lid that comes with the sheet pan. If properly covered, this cake should stay fresh for about five days when refrigerated.
