Ingredients

Units Scale

For the Cupcakes:

  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 3/4 cup brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup mashed banana
  • 1/4 cup dark rum
  • 1/4 cup buttermilk

For the Frosting & Topping:

  • 1 cup heavy whipping cream
  • 3 tablespoons powdered sugar
  • 1/2 teaspoon vanilla extract
  • 1/4 cup caramel sauce

Instructions

  • Preheat & Prep:

    • Preheat the oven to 350°F (175°C).
    • Line a muffin pan with cupcake liners.
  • Make the Batter:

    • In a bowl, whisk together the flour, baking powder, baking soda, and salt.
    • In another bowl, beat the butter and brown sugar until light and fluffy.
    • Add eggs one at a time, mixing well after each addition.
    • Stir in the vanilla extract and mashed banana.
    • Gradually mix in the dark rum and buttermilk, alternating with the dry ingredients, until just combined.
  • Bake the Cupcakes:

    • Divide the batter evenly among the cupcake liners, filling each about ¾ full.
    • Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
    • Let cool completely before frosting.
  • Make the Frosting:

    • In a bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form.
  • Assemble & Serve:

    • Pipe or spread the whipped cream frosting onto the cooled cupcakes.
    • Drizzle caramel sauce over the top before serving.

Notes

  • Boozy Option: For extra rum flavor, brush the tops of the warm cupcakes with a little extra dark rum.
  • Storage: Store in the refrigerator for up to 3 days. Let cupcakes come to room temperature before serving.
  • Non-Alcoholic Option: Substitute the rum with an equal amount of milk or apple juice.
