  • ½ cup unsalted butter room temperature
  • 2 cups powdered sugar
  • 1 teaspoon Rodelle Chocolate Extract or vanilla extract
  • 1 tablespoon milk


  • Preheat oven to 350 degrees. Spray an 8 inch square baking pan or line with parchment paper.
  • In a measuring cup mix the milk and the vinegar and set aside.
  • Mix the butter and sugar together until light and fluffy.
  • Add eggs, Rodelle Vanilla and banana and mix until well combined.
  • In another bowl whisk together the flour, baking powder and baking soda.
  • Alternate adding the flour mixture and milk mixture and continue to stir until well combined.
  • Pour into the baking pan and cook for 20. minutes or until a toothpick inserted in the center comes out clean.
  • Remove from oven and cool well on a cooling rack before frosting. I suggest at least one hour.


  • Cream butter and Rodelle Chocolate Extract in a mixer until it's fluffy.
  • Add powdered sugar a little at a time and continue to mix well until fluffy. Add the milk and beat at high speed. You can add a tad more milk if it's too thick.


I have not made this cake with any other gluten free flour.  I have the most success with Bob's Red Mill and can't recommend any other brand in this recipe.
Feel free to leave out the chocolate extract and add vanilla extract instead.
