frequently asked questions
you want to use the exact measurements indicated because protein powder has a tendency to dry out cake. by adding the fats such as greek yogurt and buttermilk, this cake recipe retains the perfect amount of moistness!
by creaming the fats and sugar together, that will add extra moistness to the cake. also, this recipe uses buttermilk which is always a good choice when you want a moist cake.
i would not add any baking soda to this recipe or replace the baking powder with baking soda. baking powder has a more neutral taste as well as containing both a base and acid.
yes of course!! i will never argue with adding some chocolate chips or chunks. this cake recipe is able to hold up to any additional mix-ins.
you could make this cake vegan friendly by making vegan buttermilk, eggs and using vegan yogurt. however, i have not tested this recipe using those ingredients and may not come out as well as it would with the ingredients below.

Oh, any time I can find a dense chocolate cake I know I have to have it! This is such an awesome recipe.
This cake is good! Not too sweet, but chocolatey and satisfying. I made a quick frosting with a touch of maple, cacao powder, cashew butter and sea salt. I love that it's loaded with protein.
One note - you mention eggs in the post, but there are no eggs in the recipe itself. I guessed and added an egg with the sugar, buttermilk and yogurt.
Hi Sarah! I'm so sorry about that, I'll update the post now so that it's accurate with the eggs. I'm glad you were able to get it to come out well still! Your homemade frosting sounds DELICIOUS. I like to top the cake with my protein chocolate mousse sometimes when I'm really craving chocolate.
