This Peanut Butter Banana Bundt Cake is like banana bread but lighter, filled with nutty peanut flavor and a salted caramel peanut butter glaze on top!




  • 3 medium bananas (250g)*
  • 2 flax eggs (2 tbsp ground flax + 4 tbsp water)
  • 1/2 cup (70g) coconut sugar
  • 1/2 cup (125g) peanut butter
  • 1 cup (240g) nondairy milk
  • 2 cups (250g) oat flour
  • 1 1/2 cups (165galmond flour
  • 1 tbsp baking powder
  • 1 tsp cinnamon
  • 1/2 tsp salt

Peanut Butter Glaze

  • 1/4 cup (60g) peanut butter
  • 1/4 cup (40g) maple syrup
  • 1/4 cup (50g) coconut oil, melted
  • 1/2 tsp salt
  • 1 tsp vanilla extract


  1. Preheat the oven to 350ºF.
  2. Prepare flax eggs and set aside to gel for 5-10 minutes.
  3. Mash or blend the bananas.
  4. Mix together the banana, flax eggs, coconut sugar, peanut butter, and nondairy milk.
  5. In a separate bowl, combine the oat flour, almond flour, baking powder, cinnamon, and salt. Whisk to eliminate any clumps.
  6. Add the wet ingredients to the dry, and mix to form a batter. 
  7. Pour into a bundt pan** (mine was 10 cup but 8-cup would be fine too) that has been generously sprayed with nonstick spray.
  8. Bake for 40-45 minutes at 350ºF.
  9. Remove from the oven. Cool for 10 minutes. Flip onto a cooling rack to cool completely.
  10. Whisk together the glaze ingredients until smooth. If it’s too thick, microwave for 5-10 seconds.
  11. Spoon glaze onto cooled cake, and sprinkle with chopped roasted peanuts.
  12. Enjoy! Keep leftovers covered in the refrigerator for up to a week.


*About 1 cup after mashing. You can either mash with a fork, or blend to a puree if you don’t want any chunks.

**If you don’t have a bundt pan, cupcakes/muffins would be the best alternative. They will bake for slightly less time (about 30-35 minutes). You could try baking it in a regular cake pan, but I don’t recommend a loaf pan for this recipe.
