How to Make Butterfinger Cupcakes
- Step 1. Preheat the oven and prepare the pan with cupcake liners. Preheat the oven to 350 degrees Fahrenheit and line 2 cupcake tins with cupcake liners.

Step 2. Crush the Butterfinger candy bars into small pieces. You can use a food processor. If you don’t have one, use a ziplock bag and crush with a rolling pin. Save some of the crushed candy bars for the topping.

Step 3. Stir in the eggs, vegetable oil, milk, sour cream and tsp vanilla extract. Mix until combined.

Step 4. Then add in the dry ingredients and stir until the mixture is smooth.

Step 5. Pour the batter into the cupcake liners.

Step 6. Bake the cupcakes for 18-22 minutes or until a toothpick inserted into the center comes out clean. Allow to cool on a wire rack.

Step 7. While the cupcakes cool, make the frosting. In the bowl of an electric mixer, whisk together butter and peanut butter until smooth and fluffy. You can also use the bowl of a stand mixer with the paddle attachment. Make sure to scrape the sides of the bowl.

Step 8. Gradually add the powdered sugar on low speed, alternating with a tbsp milk or heavy whipping cream at a time, until desired consistency.

Step 9. Pipe the frosting onto each of the cupcakes. I used a star decorating tip. Then garnish with crushed candy bars. You can also top with chocolate chips or chocolate ganache and sea salt. It’s great with Homemade Butterfinger Ice Cream.
Storage
Refrigerate the leftover cupcakes in an airtight container for up to 3-4 days. If you have one of those cupcake carriers, they are so handy for storage and keep them fresh.
You can freeze the cupcakes before they are frosted and decorated. Wrap in plastic wrap and place inside a freezer container.
Freeze the cupcakes up to 3 months. When ready to use, thaw overnight in the fridge. Then make the frosting and decorate as normal.

Pro Tips
- Piping bag for easy decorating. If you do not have a piping bag, place the frosting in a ziploc bag. Cut the corner off and pipe the frosting on the cupcakes.
- Chocolate Drizzle. For more chocolate flavor, drizzle chocolate sauce on top of the cupcakes.
- Creamy peanut butter. We recommend using a creamy peanut butter variety in this recipe. The texture will be perfectly smooth and loaded with peanut butter flavor.
- Make ahead option. You can make the cupcakes up to 3 days in advance and then decorate when ready to use. The frosting can be prepared up to 1 day in advance.
- Decorating the cupcakes. In addition to Butterfinger candy bar pieces, you can also use Butterfinger baking chips, peanut butter baking chips or chopped peanuts.
- Softened butter. The butter should be softened at room temperature before making the frosting. The texture will be smoother, and the ingredients will combine better.
- Allow to cool. The cupcakes need to cool completely before frosting. It will not hold its shape and start to melt if decorated too soon.
