  • Has an equal ratio of protein:carbs to provide long lasting energy
  • Can be made ahead of time
  • Great for a grab-and-go breakfast
  • Perfect for a pre or post workout meal
  • A great brunch idea for the whole family
  • It’s cake…who doesn’t like cake?!

This baked breakfast “treat” is super tasty!!! It is moist but with a slightly crisp outside! It is almost a mix between a cookie and cake…you can easily pick it up and eat it cold, or serve it warm with your choice of toppings!

Ingredients: (base recipe) Makes 12 slices/12 servings

  • 2 cups dry (old-fashioned) rolled oats
  • 4 scoops vanilla whey/casein blend protein powder*
  • 2-4 tbsp baking Stevia (or to taste)
  • 1 tsp baking powder
  • dash of salt
  • 1 medium banana (1/2 cup mashed/60g total weight)  1/2 cup canned pumpkin OR unsweetened applesauce
  • 1/2 cup nonfat plain greek yogurt
  • 1 tsp vanilla extract
  • 1 cup unsweetened almond milk
  • 1 whole egg
  • 2 egg whites

Optional Ingredients:

  • 1/2 cup berries (fresh or frozen)
  • Cinnamon

* I personally use Dymatize Elite XT Extended Release Protein Powder for my baking recipes. I have tried other whey protein powders, and this one specifically provides the richest flavor and a super moist texture in my recipes. You can find this online, Vitamin Shoppe, etc.

**For a dairy free recipe, feel free to omit the yogurt and use all banana, or even applesauce, pumpkin, etc. Do keep in the mind the protein/carb ratio will change.


Pre-heat your oven to 350F.

Mix all the dry ingredients together in a large mixing bowl.

In a separate bowl, combine the remaining wet ingredients (except the berries, crushed nuts, etc.) and mix well.

Slowly add the wet mixture to the dry ingredients and stir thoroughly together. The “batter” should be thick, almost the consistency of a big bowl of cold oatmeal 🙂 . It should not be too dry like a cookie batter and also not too runny.

Pour your mixture into a well-sprayed casserole or pyrex dish. I personally like using a round dish, but feel free to use whatever you have. (They might end up being more breakfast “squares” than cakes ;))

If using them, add your berries now by “dropping” them into the dish and “fold” them in gently. (I find this works better, as they do not drop all the way to the bottom).

Bake your breakfast cake at 350F for about 35 minutes. Check at 30 minutes; the cake should be slightly brown on top and pulled away slightly from the sides. A toothpick/fork should also come out clean (from the center).

I like to enjoy this with warmed berries and a little whipped cream on top! YUM! Enjoy!! 🙂
