- 1 tsp vanilla extract
- 3 large egg whites, room temperature
- 1 1/4 cups all-purpose flour
- 2 tsp baking powder
- 1/4 tsp salt
- 6 tbsp milk, room temperature
- 2 tbsp water, room temperature
- 1/2 cup crushed Butterfingers
- 5 oz semi-sweet chocolate chips
- 6 tbsp heavy whipping cream
- 1/2 cup salted butter
- 1/2 cup peanut butter
- 1/4 cup shortening
- 3 1/2 cups powdered sugar

Directions

- In a mixing bowl, cream together the sugar, brown sugar, and unsalted butter until the mixture is light and fluffy.
- Mix in the peanut butter, sour cream, and vanilla extract until well combined.

- Divide the batter into the cupcake liners, filling each about 2/3 full.

- Frost the cooled cupcakes with the peanut butter frosting, then drizzle with chocolate ganache.
How to Serve Butterfinger Cupcakes
