  • 2 very ripe large bananas, broken into 2 inch chunks
  • 2/3 cup oat milk
  • 2 large eggs (or 3 medium)
  • 1/8 cup + 1 Tablespoon maple syrup
  • 1/4 cup peanut butter*
  • 1 teaspoon vanilla extract
  • 1.5 cups rolled oats, divided
  • 1 teaspoon baking powder
  • 1 teaspoon cinnamon
  • 1/2 teaspoon salt
  1. Preheat oven to 350 degrees F. Lightly grease a 9x11 or 8x8 baking dish and set aside.

  2. Attach the whisk attachment to a stand mixer. To the stand mixer bowl, add the bananas, oat milk, and eggs and whisk on low for 1 minute. Add the maple syrup, peanut butter and vanilla and whisk for another minute, until well combined.

  3. In a mini blender, pulse 3/4 cup of the oats for 4-5 seconds, until they resemble coarse sand. Add the pulsed oats, remaining 3/4 cup rolled oats, baking powder, cinnamon and salt to the wet ingredients in the stand mixture. Whisk for 1 minute, until well combined.

  4. Add the batter to the greased baking dish and bake for 35-40 minutes, until lightly golden on the edges, and a toothpick inserted into the center comes out clean. Allow to cool in the baking dish on a wire rack for 30 minutes. Then slice into squares and store in an airtight container.


*If your peanut butter doesn't contain salt, add 1/8 teaspoon salt with the dry ingredients.
