I had a friend over to bake recently, and she wanted to make a lemon cake with vanilla frosting. So we created this Lemon Protein Cake with Vanilla Yogurt Protein Frosting! (Look how creamy that frosting is!)

I labeled this cake as "intermediate" only because of the effort involved. It's a simple recipe, but sometimes I'm just too lazy to zest a lemon. :)
We used the Sun Warrior Warrior Blend protein powder, as I have been often lately. It has a great flavor and texture!
We baked the cake as one cake and cut it lengthwise to make layers, as I did with my Confetti Birthday Protein Cake. The creamy frosting hides any bumps in the baked cake.

🥣 Recipe
Ingredients
Lemon Protein Cake:
- 8 large egg whites 264g
- zest of one lemon
- ¼ cup lemon juice 61g (1 ½ - 2 lemons)
- ⅓ cup fat-free Greek yogurt 76g
- 1 cup Warrior Blend Vanilla protein powder 100g
- ¼ cup almond meal 28g
- 1 teaspoon baking powder 5ml
Vanilla Yogurt Protein Frosting:
- 1 ½ cups fat-free Greek yogurt 340g
- ¾ cup natural vanilla whey protein powder 69g
- 2 teaspoons alcohol-free vanilla extract 10ml
Instructions
- Preheat oven to 325F (163C).
- Line a 7″ round baking pan (or similar size) with parchment paper (if not using silicone).
- Mix all the cake ingredients (by hand, electric mixer, or blender).
- Pour cake batter into pan.
- Bake at 325F (163C) for about 30 minutes, until the cake is firm to the touch and a toothpick comes out clean.
- While the cake is baking, make the frosting by mixing the ingredients until smooth.
- Set frosting in the freezer to firm up while the cake bakes and cools.
- Once cool, cut the cake lengthwise to make 2 layers.
- Frost bottom layer, then set top layer in place. Frost top and sides.
- Slice, and enjoy!
- Store in the refrigerator.
Notes
Almond meal can be made by pulsing almonds in a food processor. Sift out the large pieces and pulse again. Be careful not to overprocess, as this will give you almond butter.

Hi Alexis,
I'm sorry, I didn't see this comment when it came in!
Yes, I think both of those things would affect the density of the cake. If you're using egg whites from a carton, I'd suggest using an electric beater for sure (not sure if you did). Also the pastry flour and almond meal are very different. I haven't used pastry flour in any of these recipes, as I'm trying to keep the carbs down, so I can't say for sure if there's a way to make the substitution work. But almond meal is just ground almonds, and that is very different texturally than a wheat flour. Let me know if I can be of further assistance. And apologies again for the delay in response!

Hi Andrea! I just tried making this cake and it turned out pretty dense, not like in the picture, so I was wondering if you could possibly tell me where I went wrong? I did use organic egg whites from a carton and 1/3 cup ww pastry instead of almond meal, so would that affect it? Thanks!
