Scale
For the cupcakes
- 1 1/4 cups + 2 tbsp. (190g) all-purpose flour
- 2 tbsp. cornstarch
- 1/2 tsp. baking soda
- 1/4 tsp. salt
- 3/4 cup mashed ripe bananas (about 2 medium bananas)
- 1/2 tsp. lemon juice
- 1/4 cup (60g) butter, at room temperature
- 2 tbsp. vegetable oil
- 1/2 cup (100g) sugar
- 1/4 cup (60g) brown sugar
- 1 large egg
- 1 large egg white
- 1/2 tsp. vanilla extract
- 2/3 cup (160ml) buttermilk
For the Nutella buttercream
- 1/2 cup (115g) butter, room temperature
- 1/4 cup (80g) Nutella
- 2 1/2 tsp. cocoa powder
- 1/2 tsp. vanilla extract
- 2 cups (260g) confectioner’s sugar
- 3–4 tsp. heavy cream
For decoration
- cocoa powder for dusting, chopped hazelnuts, chopped chocolate or sprinkles (optional)
Instructions
- Preheat the oven to 350˚F (175°C). In a mixing bowl combine flour, cornstarch, baking soda and salt. Set aside. Line mini cupcake tins paper liners.
- Mash the bananas and mix with the lemon juice. Set aside. In a large bowl mix butter, oil and sugars until light and fluffy. Add egg and egg white and mix well. Add vanilla extract and the mashed banana and mix. Add the flour mix alternating with the buttermilk in several portions. Do not overmix. Fill the batter into the paper liners, each about 2/3 full. Bake for 12-14 minutes – a toothpick inserted in the center should come out clean. Let cool down completely on a wire rack.
- In a large bowl beat the butter until light and fluffy – about 5-6 minutes. Add Nutella and cocoa powder and mix for another 2-3 minutes. Add vanilla extract and confectioner’s sugar and mix on low speed until well combined and then on high speed for another 3 minutes. Add the heavy cream one teaspoon after another and mix until you get the desired texture of the buttercream. Fill in a piping bag with star tip and decorate the cupcakes with a small swirl. Dust with cocoa powder or sprinkle with hazelnuts/sprinkles (optional).
Notes
- Enjoy baking!
