Who doesn’t love cake? Well, if we’re getting technical, I hate chocolate cake, but don’t hold it against me. All other types of cake… LOVE. But, sadly, we know we can’t eat cake like this everyday:
So, let’s get baking and make a healthy substitute! This is easily my favorite recipe to make (I think I buy bananas just to let them ripen as an excuse to bake it). All you need is about 45 minutes, 11 ingredients, and an oven.

You can if you make it healthy!! What good is having cake but not eating it? That’s not being selfish.
Ingredients:
- 3 ripe bananas
- 2 scoops protein powder (I used BSN Lean Dessert in banana)
- 2 TBSP powdered peanut butter (PB2)
- 2 TBSP chopped walnuts
- 2/3 cup oats
- 1/2 cup oat flour
- 1/4 cup egg whites
- 1 tsp baking soda
- 1 tsp baking powder
- cinnamon to taste
- maple extract to taste (optional, could use vanilla too)
Bake it!
- Preheat oven to 350. Mash bananas in a mixing bowl.
- Add remaining ingredients and combine well.
- Add a splash of maple (or vanilla extract), and cinnamon – try the batter and see if it’s sweet enough. Add more as needed. Optional: could add a pinch of brown sugar if you want it sweeter, I left this out of mine.
- Pour batter into a glass dish sprayed with cooking spray.
- Bake for approximately 30 minutes, until a toothpick inserted in the middle comes out clean. Edges should be brown, but the middle should be slightly soft to the touch.

The batter will be very similar to cake batter. It’s great with some peanut butter (of course), with fruit, or as a topping. Enjoy!
This is really good plain, but I love to add it to my last meal of the day: plain Greek yogurt with vanilla casein protein powder mixed together. I crumbled a piece of the cake into my yogurt for some added nutrients and texture.
Nutrient breakdown per slice:
Carbs | Protein | Fat | Calories |
15 | 6 | 3 | 110 |
I calculated this as 12 servings per cake. Those are fairly large pieces, I probably get double the servings out of it to make it last longer.
