Seriously, the combination of fresh, wholesome blueberries and natural lemon flavor make this cake taste absolutely divine! If you like blueberries and lemon, then you'll really LOVE this cake!
For the cake:
1/2 C. butter (salted, room temp.)
1/2 C. granulated sugar sub. (I used erythritol)
20 drops vanilla stevia extract
4 large eggs (room temp.)
1/2 C. sour cream (full fat, room temp.)
1/8 C. fresh squeezed lemon juice
2 tsp. lemon zest
3 C. almond flour (I use Honeyville)
1/4 C. plain whey protein
2 tsp. baking powder
1/2 tsp. baking soda
1 C. fresh blueberries (plus a few extra for decoration)
For the frosting:
3 C. heavy whipping cream
1 8 oz. pkg of full-fat cream cheese (room temp.)
1 TBLS. fresh squeezed lemon juice
1 tsp. lemon zest
A few packets of Truvia, or stevia, or other sweetener--to taste.
Directions
1. Preheat oven to 350 degree F. Mix the butter and sugar sub. and liquid stevia. Then mix in the eggs, sour cream, lemon juice and zest, followed by the almond flour, whey protein, baking powder and baking soda.
2. Very gently and slowly fold in the blueberries. Don't mix too much.
3. Spread the thick batter into two spray-greased 8" or 9" round cake pans (I used 9", but I think the 8" would make thicker cake layers.) Also, after spraying the pans, place a round piece of parchment paper in the bottom of the pans and spray those, too. This batter has a tendency to stick.
4. Bake for approx. 25 - 30 min., or until a toothpick inserted in center comes out clean. For a moister cake, it's better to slightly under bake it than slightly over bake it.
5. Remove cakes from oven and allow to cool in the pans for about 15 min. Slide a knife around outer edge of the cakes, between the cake and the pans, then place a plate on top of each cake pan and invert the cakes. Allow the cakes to continue cooling on the plates.
6. Make the frosting by beating the whip cream to soft peaks. Then mix in the cream cheese, lemon, zest, and sweetener and beat to desired texture.
7. Frost one cake layer, then carefully place the 2nd cake layer on top of the first layer and frost the remaining cake. Decorate with a few blueberries.
8. Keep refrigerated when not serving. Makes approx. 14 servings. Enjoy!!
