Now, let’s talk about the ingredients!

Ingredients List

  • Chocolate Protein Powder – You can use any protein powder that you prefer. However, I have made this with both vegan and whey protein. I recommend using vegan protein powder when baking because whey can dry out the cake texture.
  • Egg – Use a large egg for this recipe, however, extra large will work if that’s what you have on hand.
  • Banana – A medium sized banana is the perfect amount for this recipe. I use 3/4 of the banana in the batter then slice the rest for a topping. Make sure to mash it up well so that there aren’t massive clumps in the batter.
  • Unsweetened Cacao Powder – I typically use an Unsweetened 100% Cocoa Powder, such as the brand linked.
  • Vanilla Extract – You can use any brand preference of vanilla extract that you like.
  • Baking Soda – This can be found at your local store and can be any brand.
  • Baking Powder – This can be found at your local store and can be any brand.

Frequently Asked Questions

Can I make this on a bigger scale?

yes! you can make as many servings as you want by multiplying the measured ingredients based off of how much you want to make.

I also have this small batch chocolate cake recipe that uses similar ingredients but makes it in a larger pan.

Can I add toppings to the cake?

add any toppings/ingredients that you’d like. this recipe is adaptable to your flavor preferences. some suggested toppings are banana slices, fresh fruit, chocolate chips, peanut butter or a honey drizzle. the limit really doesn’t exist!

Can I make this recipe vegan friendly?

You can make this recipe vegan friendly by using a vegan protein powder. Rhe only other thing you’ll need to do is use a flax egg instead of a regular egg.

A flax egg is 1 tbsp of ground flax seed mixed with 2 tbsp of water. Let the mixture sit for 5-10 minutes before adding into the batter. This will allow the mixture to thicken and act as an egg!

Can I make this recipe ahead of time and eat later?

Yes! I suggest making this no sooner than the night before you plan to eat it but it is best when eaten fresh!

Can I make this in the microwave?

I haven’t tested this recipe in the microwave yet but I am on it and will update you all here when I have.
