Banana Cake with Chocolate Peanut Butter Ganache- A sweet, fluffy vegan banana cake with the easiest chocolate ganache!


  • For the cake:
  • 1 large banana (smushed)
  • 6 tablespoons granulated sugar
  • 1 tablespoon ground flax seed
  • 3 tablespoons warm water
  • 2 tablespoons olive oil
  • 3/4 teaspoon vanilla extract
  • 1/4 cup full fat coconut milk
  • 3/4 cup all-purpose flour
  • 1/4 teaspoon ground cinnamon
  • 1/8 teaspoon fine sea salt
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • For the ganache:
  • 1 cup semisweet chocolate chips
  • 1/2 cup peanut butter
  • 2 tablespoons coconut oil


  1. Preheat oven to 375 degrees F. and line a bread loaf pan with parchment paper.
  2. In a small bowl, combine the ground flax seed and water together. Set aside.
  3. In a medium size bowl, smash the banana very well until almost no lumps remain.
  4. Next, stir in the sugar, flax seed+ water, oil, and vanilla extract. Stir very well until blended.
  5. Add the full fat coconut milk and stir until evenly incorporated.
  6. In a separate small bowl, whisk together the flour, cinnamon, salt, baking soda, and baking powder.
  7. Add the dry ingredients to the bowl of wet ingredients and stir until combined.
  8. Pour the batter into the loaf pan and bake for 28-32 minutes, or until a toothpick comes out clean.
  9. Let the cake cool on a wire rack.
  10. While the cake is cooling, make the ganache by combining the chocolate chips, peanut butter, and coconut oil in a microwave safe bowl. Microwave on high for 30 second intervals, stirring between each time until chocolate is fully melted.
  11. Once cake has cooled and ganache has been made, cut the cake and pour ganache over each piece.
