Take a look at this chocolate protein cake. Do I really need to write anything here? ;)

Chocolate Protein Cake

I wasn't planning on making a devil's food protein cake. I was working on a recipe for whoopie pies (a reader request), and the cookies came out great! So I scaled up the recipe, made some frosting, and now we have a moist and delicious chocolate protein cake!

Chocolate Protein Cake

Also unplanned was the rugged shape of the cake, which I love. That happened because I was too lazy to cut my parchment paper to properly line the pan. I just put the whole sheet in, pressed it down, and poured in the batter.

The cake is egg-free, gluten-free, grain-free, nut-free, and pretty simple to make! No fancy ingredients, here: whey protein, applesauce, cocoa powder, baking powder, and a touch of salt. The frosting is made from soaked raw cashews (which make a great Cashew Whipped Cream) with some chocolate whey, cocoa, and stevia. I went for a lighter frosting because this cake is a bit more delicate than other recipes I've made, and I didn't want the cake to break as I frosted it. That's also the reason I baked it as two separate cakes, unlike my Confetti Protein Birthday Cake (and some others) that I bake as one cake and slice. Also, I used black cocoa here, but regular cocoa would also be delicious!

Even without the frosting, this cake is amazing. Try it. You'll thank me. ;)

Prep Time 15 minutes mins
Cook Time 20 minutes mins
Total Time 35 minutes mins
Servings 6

Ingredients

Cake:

  • 2 cups natural chocolate whey protein 180g
  • ½ cup cocoa powder 40g (I used black cocoa)
  • 1 ½ cups unsweetened applesauce 500g
  • 2 teaspoons baking powder
  • ¼ teaspoon sea salt

Frosting:

  • 1 ½ cups raw cashews 170g, soaked for 4 hours or more in filtered water
  • ½ cup water (or more, as needed)
  • 2 tablespoons cocoa 10g (I used black cocoa)
  • 2 packets stevia 2g
  • ¼ cup natural chocolate whey protein 23g

Topping:

  • cacao nibs optional

Instructions
 

  • Drain and rinse cashews, and put in blender.
  • Add ½ cup filtered water to blender, and blend cashews to a cream. If needed, add more water by the tablespoon (15ml).
  • Add cocoa, stevia, and whey powder. Blend until smooth.
  • Put frosting in the freezer to cool while you bake the cake.
  • Preheat oven to 325F (163C).
  • Line two 6" round (or similarly sized) pans with parchment paper (or use 1 pan, and bake them one at a time).
  • Mix all cake ingredients until well combined.
  • Pour half the batter into each pan.
  • Bake for about 15 minutes, and see if the cakes are firm. Check every 1-2 minutes, and remove as soon as they are firm. Be sure not to over-bake these cakes!
  • As the cakes are baking, stir the frosting and set back in the freezer.
  • Let the cakes cool.
  • Spoon half the frosting on the bottom layer.
  • Set the top layer in place, and spoon remaining frosting on top.
  • Top with a few raw cacao nibs, if desired (not included in macros, but would hardly change them anyway).
  • Slice, and enjoy!
  • Store in the refrigerator.

Notes

A note about substitutions: because each type of protein powder has a distinct flavor and texture when baked, I would not try substituting different types of protein powder in the recipe for the cake. (Vegan proteins would need egg whites and less applesauce for the proper cake-like texture, and probably still wouldn't match the moist, airy texture here!) For the frosting, a vegan protein like Vega Sport should work, but others may be too chalky. Casein can also be used in the frosting in place of the whey.
If you are making one single-layer cake, you can just use one 8" round pan, and the timing should be similar.
Macros for ⅙ of the unfrosted cake are: Prot: 24 g, Carbs: 17 g (Fiber: 3g, Sugar: 10g), Fat: 2 g, Cal: 177.
Also, when using parchment paper like I did, be sure to trim the top edges of the paper (after the batter is in the pan) so that the parchment doesn't touch the roof of your oven. Parchment is paper, after all, and it will burn if it touches oven surfaces.

    Hi Ishika, mashed banana would be a great sub! Or canned pumpkin. (Apologies for the late reply.)
