Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Cupcakes:
1 1/3 cup all‑purpose flour
2 1/2 tablespoons cornstarch
1 1/4 teaspoon baking powder
3/4 teaspoon baking soda
1/8 teaspoon salt
5 tablespoons butter, softened
3/4 cup sugar
2/3 cup mashed banana
1/3 cup buttermilk
2 eggs

For the Frosting:
1 cup butter
1 teaspoon vanilla
3 cups powdered sugar
2–3 tablespoons cream or milk

For the Ganache:
1/3 cup whipping cream
2/3 cup semi‑sweet chocolate chips

For the Toppings:
Sprinkles
Whipped cream
12 Maraschino cherries

Directions

Preheat your oven to 350°F (175°C) and line a muffin tin with 12 cupcake liners.
In a large bowl, whisk together the flour, cornstarch, baking powder, baking soda, and salt.
Using an electric mixer, beat the softened butter and sugar until light and fluffy. Add in mashed banana, buttermilk, and eggs, and mix until combined.
Gradually add the dry ingredients to the wet mixture, mixing until just combined. Divide the batter evenly among the cupcake liners.
Bake for 15–18 minutes, or until a toothpick inserted into the center comes out clean. Cool the cupcakes completely on a rack.
For the frosting, beat together butter, vanilla, and powdered sugar until smooth; add cream or milk to reach your desired consistency. Pipe or spread onto cooled cupcakes.
To make the ganache, heat the whipping cream until hot (but not boiling) and pour it over the chocolate chips. Let sit for 2 minutes, then stir until melted and smooth. Allow to cool slightly before drizzling over the frosting.
Decorate each cupcake with sprinkles, a dollop of whipped cream, and a cherry. Serve immediately or refrigerate until ready to enjoy.
