Peanut Butter Banana Cake (3 Ingredients, Vegan)

Peanut Butter Banana Cake (3 Ingredients, Vegan)


Baking in the dorm kitchen is always an adventure for several reasons:

  1. You never know what pans are actually clean.
  2. There is no working mixer.
  3. I have to carry the ingredients from my room to the kitchen (and always have to go back because I forget to take cooking spray).
  4. There are no pot holders.
  5. There is no cake tester, so sometimes I poke holes in the cake and try a piece before I remember to take pictures of the final product.


Yet, I love to bake, and my hall loves cupcakes, so I find myself vigorously stirring batter every few weeks.


Several weeks ago, I bought bananas for ten cents a pound. Like all discounted bananas, they were mushy before I could eat them all. Nonetheless, I believe that it is an unpardonable sin to throw away bananas because you can always bake with overripe bananas. I also found powdered peanut butter at a discounted price.  I decided to combine the two ingredients, and this simple banana bread was the result.


You may have noticed that I tagged this recipe as vegan.  The truth is, I am only 99% sure that the recipe is vegan. Since I am not vegan myself and never will be (it is a proven fact that my body needs dairy to function), I do not know what vegans exclude from their diets other than meat, dairy, eggs, and honey.  I do know that bananas and powdered peanut butter do not contain animal products.  If someone wants, they can enlighten me on the unpronounceable ingredients of boxed cake mix:


Whether it is vegan or not, this cake tastes delicious, costs less than $3 total, and is simple to make.  I hope you enjoy!



  • 1 box yellow cake mix
  • 4 overripe bananas
  • 1/2 cup powdered peanut butter
  • 1 tbs. cinnamon (optional)
  • water (as needed)


  1. Preheat oven to 350 degrees Fahrenheit.
  2. Mash bananas.
  3. Combine cake mix and mashed bananas completely.  Stir in powdered peanut butter and cinnamon, adding water as needed.
  4. Coat a sheet pan with nonstick spray.  Pour batter into pan.
  5. Bake for 10-12 minutes.
  6. Let cool completely.  Eat and enjoy!

Oats and Outfits: Sunday {Banana Bread Brunch}


Wow!  I have made it through the whole week! Seven full days of Oats and Outfits!  There is a remaining form of oatmeal I have yet to eat this week, and I am so excited to make this baked oatmeal recipe.

To match my “Sunday Brunch” dress, I am making banana bread baked oatmeal.  This is my first time ever making this recipe, and I absolutely love it.  It tastes just like banana bread, and the dried cranberries give it a nice punch of tartness.  If you don’t like cranberries and coconut, feel free to use any other mix-ins you want–peanut butter, chocolate chips, walnuts, anything!
