  • 6 tablespoons butter, softened, plus more for greasing
  • 1/2 cup granulated sugar
  • 2 large eggs, room temperature
  • 1/2 cup full-fat Greek yogurt, room temperature
  • 2 teaspoons vanilla extract
  • 3 medium extra ripe bananas, equal to 1.5 cups mashed very well
  • 1.5 cups whole wheat pastry flour 
  • 1/2 teaspoon ground cinnamon
  • ¾  teaspoon baking soda
  • ¾ teaspoon baking powder
  • 1/4 teaspoon fine sea salt


  • 1 (13.5 ounce) can coconut cream, chilled for at least 8 hours
  • ⅓ cup all-natural creamy peanut butter
  • ¼ cup honey


  1. Preheat oven to 350ºF and grease half sheet or 9×13 inch cake pan with butter; set aside.
  2. Mix wet ingredients: In a large bowl using an electric hand mixer, beat butter butter and sugar until light and fluffy. Add in eggs, yogurt and vanilla, mixing on low speed until combined.
  3. Combine: Fold in bananas and dry ingredients, stirring gently until combined.
  4. Bake: Pour batter into prepared baking pan and bake for 18-22 minutes, or until an inserted toothpick comes out clean.
  5. Make frosting: While the cake is cooling, make the frosting by using an electric mixer to whip together chilled coconut cream, peanut butter and honey until light and fluffy. Use a chilled bowl if possible to keep coconut cream really cold.
  6. Serve: Spread onto cooled cake and serve!


This cake is delicious on it’s own too, if you prefer to leave out the frosting. Feel free to add in ½ cup mini chocolate chips in its place or in addition to!
