Banana Cupcakes

  • 1 1/2 cup flour
  • 3/4 cup sugar
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1/4 tsp salt
  • 1 1/2 cup mashed bananas (about 5 small, or 3 medium bananas)
  • 1/4 cup vegetable oil
  • 1 tsp vanilla extract
  • 1 egg (lightly beaten)

Brown Sugar Buttercream Frosting

  • 1/3 cup flour
  • 1 cup milk
  • 1 tsp vanilla extract
  • 1 cup butter (softened) (2 sticks)
  • 1 cup dark brown sugar (firmly packed)
  • 1 Tbs raw sugar (sugar in the raw) (optional)


Banana Cupcakes

  • Preheat oven to 350 degrees, line muffin tin with wrappers, set aside.
  • In a bowl, whisk together the flour, sugar, baking powder, baking soda and salt.
  • In another bowl, combine the bananas, oil, vanilla and egg.
  • Add the wet mixture to the dry and mix until JUST combined (don't overmix it)
  • Scoop batter into 12 cupcake liners. I used a large cookie scoop to do this, but aim for 2/3 full.
  • Bake for 18 minutes, or until they spring back when you touch them lightly.
  • Cool in the pan for a few minutes, then set on a wire cooling rack until completely cool. Frost.

Brown Sugar Buttercream Frosting

  • In a saucepan, whisk together the flour and milk and cook over medium heat, whisking continuously until thickened to a smooth paste.
  • Remove from heat, stir in the vanilla and let cool to room temp.
  • Using a stand mixer fitted with the wire whisk, cream the butter and sugar until light and fluffy. There should be no grittiness.
  • Add in the milk mixture and beat it on high speed until you get a whipped cream consistency.
  • Frost cupcakes, and sprinkle with demerara sugar.
