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, start by beating the egg whites until firm peaks develop. I suggest that you use clean mixer attachments to do so. .
- Use a rubber spatula to fold in the blueberries to the batter. Then 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 the cake 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, simply combine the listed frosting ingredient. Refrigerate the cake for at least an hour before serving to allow for the frosting to set.

- While my cake is made with blueberries, you could use another fruit with or instead of the blueberries. I like strawberries for example.
- You can make this cake into a birthday or celebration cake. Sugar free sprinkles can be found here.
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.
