Banana Cake
- 2 small bananas, mashed (about 1 cup)
- 1/2 cup sugar
- 1/2 cup oat milk (or any plant-based milk)
- 1/4 cup oil (I used olive oil)
- 2 Tablespoons brown sugar
- 1 Tablespoon apple cider vinegar
- 1 Tablespoon ground flaxseed (NOT a flax egg)
- 1 teaspoon vanilla bean paste (or vanilla extract)
- 1 1/2 cups pastry flour
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 1/2 teaspoon cinnamon
- 1/4 teaspoon baking soda
Cookie Butter Frosting
- 1/2 cup vegan butter
- 1/4 cup cookie butter
- 2 Tablespoons coconut cream (optional, for an extra fluffy frosting)
- 1 teaspoon vanilla bean paste (or vanilla extract)
- 1 cup powdered sugar (use more or less to adjust sweetness)
Instructions
- Preheat the oven: Preheat the oven to 350F and line an 8*8 inch square pan with parchment paper or grease the pan lightly. Set aside for later.
- Make the banana cake batter:
- Mash bananas: Add the bananas to a large mixing bowl and mash together until smooth. It’s okay if some small chunks remain!
- Add wet ingredients: Then, add the remaining wet ingredients to the bowl including the sugar, oat milk, oil, brown sugar, apple cider vinegar, ground flaxseed, and vanilla bean paste. Whisk together until well mixed.
- Add dry ingredients: Then, add in the dry ingredients starting with the pastry flour and then adding the baking powder, salt, cinnamon, and baking soda on top. Mix into a thick batter. I recommend starting with a whisk and then switching to a spatula so the batter does not get overmixed.
- Bake the cake:
- Pour and bake: Pour the batter into the pan and add to the oven. Bake for 30-32 minutes or until cooked through.
- Cool cake: Once cooked through, remove the cake from the oven and let it cool in the pan for about 10 minutes. Then carefully move to a wire rack to finish cooling completely before frosting.
- Make the cookie butter frosting & frost the cake:
- Whip butter: Once the cake has cooled completely, make the Biscoff buttercream. Add the butter to a bowl and use a standing mixer or electric mixer to whip for a minute or two until fluffy.
- Add remaining frosting ingredients: Next, add in the cookie butter, coconut cream, and vanilla bean paste and whip with the butter for another minute or two until mixed together.
- Add powdered sugar: Gradually mix in the powdered sugar until incorporated. Once all the powdered sugar has been mixed in, I recommend whipping the frosting for a few minutes longer to make it extra fluffy!
- Frost the cake: Use a cookie scoop to add the frosting to the banana cake and then spread it out with a cake spatula.
- Serve: Enjoy the cake as is or top it with crushed Biscoff cookie crumbles and banana slices. Then, cut into 9 slices, serve, & enjoy!
Notes
- For an extra fluffy frosting, add coconut cream to the frosting mixture.
- Do not overmix the cake batter to keep the texture tender.
- Allow the cake to cool completely before frosting to prevent melting.
