Recipe type: Dessert
Serves: 12
Banana Cake:
  • ⅓ cup white sugar
  • ⅓ cup brown sugar
  • ¼ cup butter, softened
  • 2 eggs
  • 1 cup mashed bananas (~ 3 medium bananas)
  • ¼ cup strong chai tea
  • 1⅔ cups all-purpose flour
  • ½ tsp cinnamon
  • 1 tsp baking soda
  • ½ tsp salt
  • ½ tsp baking powder
Brown Sugar Bourbon Frosting:
  • 1 cup unsalted butter, softened
  • 3 cup powdered sugar
  • ½ cup brown sugar
  • 1 tsp ground cinnamon
  • ¼ tsp salt
  • 2 tbsp heavy cream
  • 1 ½ tbsp bourbon
  • ¼ cup dulce de leche
Prepare the Cake:
  1. Preheat oven to 350F. Lightly butter and flour two 8” round cake pans..
  2. In a medium bowl, cream together the sugars and butter until fluffy. Beat in the eggs, one at a time, until the mixture is smooth, then stir in the, tea and mashed bananas. If your bananas are mostly yellow, add a tablespoon of honey to the batter at this point to compensate.
  3. Mix in the flour, baking soda, salt and baking powder until just combined. Pour the batter into the prepared cake tins, doing your best to distribute the batter evenly between the two.
  4. Bake in preheated oven for about 30-35 minutes, or until the tops are firm to the touch and golden brown. Let cool in the pan for about 10 minutes, then carefully invert onto a wire rack to finish cooling completely.
Make the Frosting:
  1. While the cake is cooling, use a stand mixer fitted with a whisk attachment to combine the sugar and butter on low speed. Add the brown sugar, cinnamon and salt. Continue mixing on low until well combined, then increase speed to medium and beat for another 3 minutes. Add the cream and bourbon, continue beating for a minute or two longer, or until the frosting is fluffy and spreadable.
Assemble the Cake:
  1. Place 1 layer on a cake plate and spread half of the frosting on top. Top with a second layer of cake, then spread the remaining frosting over the top. Drizzle the top with dulce de leche. Chill for at least one hour before serving.
