Ingredients
- ½ cup sugar
- ¼ cup brown sugar
- ¼ cup unsalted butter, room temperature
- ½ cup creamy peanut butter
- ¼ cup sour cream, room temperature
- 1 teaspoon vanilla extract
- 3 large egg whites, room temperature
- 1 ¼ cups all-purpose flour
- 2 teaspoons baking powder
- ¼ teaspoon salt
- 6 tablespoons milk, room temperature
- 2 tablespoons water, room temperature
- ½ cup crushed Butterfingers
- 5 ounces semi-sweet chocolate chips (for ganache)
- 6 tablespoons heavy whipping cream (for ganache)
- ½ cup salted butter (for frosting)
- ½ cup peanut butter (for frosting)
- ¼ cup shortening or additional butter (for frosting)
- 3 ½ cups powdered sugar (for frosting)
- 3–4 tablespoons water or milk (for frosting)
- ¾ cup crushed Butterfingers (for frosting and topping)
Instructions
- Step 1: Preheat your oven to 350°F (176°C) and line a cupcake pan with cupcake liners.
- Step 2: In a large bowl, combine the sugar, brown sugar, unsalted butter, and peanut butter. Beat on medium speed with an electric mixer for about 3-4 minutes until the mixture is light and fluffy.
- Step 3: Add sour cream and vanilla extract to the bowl and mix until well combined.
- Step 4: Add the egg whites in two batches, mixing well after each addition. Scrape down the bowl sides to ensure even mixing.
- Step 5: In a separate bowl, whisk together the flour, baking powder, and salt. In a small cup, combine milk and water.
- Step 6: Add half of the dry ingredients to the batter and mix until combined. Then add the milk mixture and mix again. Finally, add the remaining dry ingredients and mix well, scraping the bowl as needed.
- Step 7: Fold in the crushed Butterfingers gently.
- Step 8: Fill cupcake liners halfway with batter. Bake for 18-20 minutes or until a toothpick inserted comes out with a few crumbs. Let cool in the pan briefly before transferring to a wire rack to cool completely.
- Step 9: For the ganache, place chocolate chips in a medium bowl. Heat the heavy cream until it nearly boils, then pour over the chocolate. Cover with plastic wrap for 3-4 minutes, then whisk until smooth. Set aside to cool.
- Step 10: To make the frosting, beat together the salted butter, peanut butter, and shortening until smooth. Add half of the powdered sugar and mix well.
- Step 11: Add 2-3 tablespoons of water or milk and mix until well combined. Add the remaining powdered sugar and beat until smooth. Adjust consistency with more liquid as needed, then stir in crushed Butterfingers.
- Step 12: Spread a layer of chocolate ganache on each cooled cupcake.
- Step 13: Pipe the peanut butter frosting over the ganache. Top with additional crushed Butterfingers and a piece of Butterfinger candy if desired.
Tips & Variations

- Substitute shortening in the frosting with all butter for a creamier texture.
- Add a pinch of salt to the frosting to balance sweetness if using unsalted peanut butter.
- Try adding chopped peanuts for extra crunch along with the Butterfinger pieces.
Storage
Store the cupcakes in an airtight container in the refrigerator for up to 4 days. Allow them to come to room temperature before serving for the best texture and flavor. Leftover ganache and frosting can be kept refrigerated and gently warmed or beaten before reuse.

Instructions
- Preheat and Prepare: Preheat your oven to 350°F (176°C) and line a cupcake pan with cupcake liners to get ready for baking.
- Cream Sugars and Fats: In a large mixing bowl, combine sugar, brown sugar, butter, and peanut butter. Using an electric mixer on medium speed, beat for 3-4 minutes until the mixture is light in color and fluffy, ensuring the best texture for the cupcakes.
- Add Sour Cream and Vanilla: Mix in sour cream and vanilla extract thoroughly for added moisture and flavor.
- Incorporate Egg Whites: Add egg whites in two batches, mixing well after each addition. Scrape down the sides of the bowl as needed to ensure a uniform batter.
- Combine Dry Ingredients: In a separate bowl, whisk together flour, baking powder, and salt. In a small measuring cup, stir together milk and water.
- Mix Batter: Add half of the dry ingredients to the wet batter and mix until combined, followed by the milk mixture. Then add the remaining dry ingredients, mixing until fully incorporated. Scrape the bowl as needed.
- Fold in Butterfingers: Stir in the crushed Butterfingers gently to distribute evenly.
- Fill and Bake: Spoon batter into cupcake liners, filling them about halfway. Bake for 18-20 minutes or until a toothpick inserted comes out with a few moist crumbs.
- Cool Cupcakes: Remove from oven and let cupcakes cool in the pan for 2-3 minutes before transferring them to a cooling rack to cool completely.
- Prepare Chocolate Ganache: Place chocolate chips in a medium bowl. Microwave heavy cream until nearly boiling, then pour over chocolate and cover with plastic wrap. Let sit for 3-4 minutes, then whisk until smooth. Allow to cool slightly.
- Make Peanut Butter Frosting: Beat butter, peanut butter, and shortening until smooth. Gradually add half the powdered sugar and mix well. Add 2-3 tablespoons water or milk and mix again. Add remaining powdered sugar and beat until smooth. Adjust consistency with more water or milk if needed. Fold in crushed Butterfingers.
- Assemble Cupcakes: Spread a layer of chocolate ganache atop each cupcake. Pipe the peanut butter frosting on top using a large round pastry tip.
- Garnish: Finish by sprinkling additional crushed Butterfingers and optionally topping with a small piece of Butterfinger candy on each cupcake.
Notes
- Make sure all dairy ingredients are at room temperature for the best batter consistency.
- Do not rush the creaming step; beating the sugars and fats until fluffy is key for a tender cupcake.
- Use an electric mixer to ensure thorough mixing of ingredients.
- Crushing Butterfingers by hand or in a sealed bag with a rolling pin works well to control chunk size.
- Chocolate ganache should be slightly cooled before spreading to prevent melting the frosting.
- Adjust the frosting thickness by adding more or less liquid to achieve the desired piping texture.
