  • 1/4 tsp sea salt
  • 1 cup dairy free milk, room temperature

Vegan Peanut Butter Frosting:

  • 1/3 cup peanut butter, smooth
  • 1/3 cup vegan butter, softened to room temperature
  • 1/3 cup coconut sugar
  • 23 tbsp coconut cream


Banana Cake:

  1. Preheat the oven to 375F and grease a 7×11 inch pan with coconut or olive oil.
  2. Add apple cider vinegar to the almond or coconut milk and let it sit while preparing the other ingredients.
  3. In a large bowl, whisk together flour, sea salt, baking soda, and baking powder. Set aside.
  4. In a medium bowl, beat together dairy free milk and vinegar mixture, maple syrup, and vanilla extract. Set aside.
  5. Fold in mashed bananas to the whisked flour until it resembles a crumbly texture.
  6. Add in about 1/3 of the wet mixture into the crumbly flour and mix thoroughly. Add in another 1/3 and continue mixing. Finally, add in the final 1/3 of the wet mixture and mix until it’s a thick batter.
  7. Pour banana batter into the sheet cake pan and place into the oven.
  8. Bake for 30-35 minutes, or until toothpick comes out clean.
