Ingredient Notes
Overripe Bananas: I love to bake with bananas. They can do it all, from Banana Bread Cinnamon Rolls to Vegan Banana Chocolate Chip Cookies and Cinnamon Swirl Banana Bread. Be sure that the bananas are really ripe for this recipe! If they aren't, the cake won't be as sweet and won't have as much banana flavor.
Non-Dairy Milk: I used oat milk, but use whatever you have on hand. Soy milk, almond milk or boxed coconut milk will all work. The non-dairy milk combined with vinegar makes a vegan buttermilk!
Canola Oil: You can use any neutral oil like grapeseed oil, vegetable oil or avocado oil. Do not use coconut oil.
Be sure to allow the cake to cool completely before frosting it. Frosting melts very easily and you will have a big mess on your hands.
Be sure to use very ripe bananas for this recipe. If the bananas aren't ripe enough, the cake will not have much banana flavor!
Creamy Natural Peanut Butter: My favorite brand is Teddie, but use whatever you have!
Vegan Butter: I like Country Crock Plant Butter Sticks and Soy-Free Earth Balance Buttery Sticks best!
Variations

Step 3. Pour the batter into a prepared 8x8 inch square baking pan and spread it out with the back of a spatula.
Step 4. And bake in a 350* oven for 40-43 minutes. Allow the cake to cool completely before frosting.
Step 5. Now, make the peanut butter frosting by creaming room temperature vegan butter and peanut butter together in a large bowl using a hand mixer. Add maple syrup and salt and mix well. Then, add powdered sugar and mix on low to combine. Finally add the vanilla and non-dairy milk and mix until light and fluffy.
Step 6. Finally, slather the Vegan Banana Cake with peanut butter frosting and serve!
Recipe FAQs
To store, wrap the cake tightly and store it in the refrigerator for up to 4 days.
Yes. If there is any mold growing on the banana skin or liquid leaking out of them, don't use them.
Peanut butter and banana is one of my favorite flavor combinations! The saltiness of the peanut butter offsets the sweetness of the banana. It's a delicious snack and a delicious flavor combo in desserts.
