Peanut Butter Icing

  • 2/3 cup confectioner’s sugar

  • 1 tablespoon creamy peanut butter
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat your oven to 350 degrees and lightly grease an 8×8 square pan or line with parchment paper.
  2. Make the Streusel Topping: Add the melted butter, brown sugar, all purpose flour, and cinnamon to a small mixing bowl. Stir together until well combined and a crumble forms. Set aside.
  3. Make the Cinnamon Layer: Add the dark brown sugar, all purpose flour, and ground cinnamon to a small bowl and stir until well combined.
  4. Make the Coffee Cake Batter: Add the melted butter, Greek yogurt, eggs, mashed banana, vanilla extract, brown sugar, and almond milk to a large mixing bowl. Whisk together until well combined.
  5. To another mixing bowl, add the all purpose flour, salt, baking powder, baking soda, and cinnamon. Whisk together until well combined.
  6. Gently fold the dry ingredients into the wet ingredients until you have a thick batter.
  7. Assemble the Coffee Cake and Bake: Transfer half the batter into the prepared baking dish and spread in an even layer. Next, sprinkle the cinnamon layer even over the batter. Next, pour the remaining batter over the cinnamon layer and smooth into an even layer.
  8. Transfer the batter into the prepared baking dish. Next, sprinkle the streusel topping evenly over the coffee cake.
  9. Bake the coffee cake at 350 degrees for 30-40 minutes or until a toothpick comes out clean when inserted into the middle of the cake. If using a ceramic baking dish the cake may take a bit longer to bake.
  10. Make the Peanut Butter Icing: Add the confectioner’s sugar, almond milk, and vanilla extract to a mixing bowl. Whisk together until well combined and smooth. Next, add the peanut butter and whisk together until smooth and creamy.
  11. Let the coffee cake cool for 20-30 minutes before drizzling the icing over the cake while warm. Slice into 9 squares and enjoy!
