Ingredients (17)

For the Cake

  • 1 cup whole wheat flour
  • ½ teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon cinnamon
  • ⅛ teaspoon salt
  • 1 medium ripe banana (about 3 ounces)
  • ⅓ cup unsweetened applesauce
  • ¼ cup whole *milk
  • ¼ cup pure maple syrup
  • 1 large egg
  • 1 teaspoon almond extract

For the Frosting

  • 1 cup frozen blueberries
  • ¼ cup water
  • 1 cup heavy whipping cream


  1. Preheat oven to 350 degrees F. Butter the cake pans with butter and lightly dust them with whole wheat flour, tapping out the excess. We prefer that you use two 4-inch spring form pans.
  2. Place frozen blueberries and water in a small saucepan. Heat over medium-low heat, stirring often, until blueberries soften and burst, about 8 minutes. Set aside to cool slightly. Transfer blueberry mixture to a blender and blend until smooth, scraping down the sides of the blender as needed. Place in a bowl to cool completely.
  3. In a large bowl, whisk together the whole wheat flour, baking powder, baking soda, cinnamon, and salt. Set aside. Place banana, applesauce, milk, and maple syrup in a blender and blend until smooth. Pour into a medium bowl or large liquid measuring cup. Whisk in the egg and almond extract. Pour the wet ingredients into the bowl with the dry ingredients and mix with a rubber spatula or spoon until it is just combined. Be careful not to overmix; it’s ok if there are a few bits of flour still visible in the batter.
  4. Pour batter into the prepared cake pans. Pans should be just over half full with the batter. Bake for about 20-23 minutes, until a toothpick inserted into the center of the cake comes out clean. Let cakes cool in the pans for 10 minutes. Then, gently run a knife around the edges and carefully transfer to wire racks to cool completely before frosting.
  5. Using an electric mixer, beat the heavy whipping cream until it is the consistency of whipped cream. Gently fold in the blueberry mixture. Frost cake as desired. To frost a double layer cake, first add a spoonful of frosting to the top of the bottom layer. Place the second cake layer on top. Using an offset spatula, spread frosting over the top of the cake and then down the sides.
