Step-by-Step Instructions
Each phase, from mixing to decorating, can influence the final texture and taste. Use this methodical approach for consistently delicious cupcakes.
1. Preheat and Prep
-
Preheat oven to 350°F (175°C).
-
Line a 12-cup muffin tin with cupcake liners.
2. Make the Cupcake Batter
-
In a large bowl, beat the butter and both sugars on medium speed until pale and fluffy, about 2–3 minutes.
-
Add peanut butter and beat until fully incorporated.
-
Mix in sour cream and vanilla, scraping down the bowl as needed.
-
Beat in egg whites one at a time until well blended.
-
In a separate bowl, whisk flour, baking powder, and salt.
-
Alternately add the dry mixture and milk to the wet ingredients in three additions, starting and ending with flour.
-
Pour in hot water and mix just until smooth (the batter will be thin).
-
Fold in crushed Butterfinger pieces using a spatula.
3. Bake the Cupcakes
-
Divide batter evenly among cupcake liners, filling each 2/3 full.
-
Bake for 16–19 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.
-
Allow to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
4. Prepare the Frosting
-
In a large bowl, beat the butter and peanut butter until light and creamy, about 2–3 minutes.
-
Add sifted confectioners’ sugar, 1 cup at a time, mixing on low and scraping the bowl as needed.
-
Blend in vanilla and salt.
-
Add cream or milk, 1 tablespoon at a time, and beat until light and fluffy. Adjust consistency as needed.
-
Fold in crushed Butterfinger bits for a textured frosting.
5. Assemble and Decorate
-
Once cupcakes are fully cool, fill a piping bag fitted with your desired tip and frost generously.
-
Sprinkle with additional crushed Butterfinger or place a small bar segment on each for garnish.

Tips for Perfect Results
Focus on these professional strategies for flawless Butterfinger Cupcakes every time.
-
Ingredient Temperature: Room-temperature butter, eggs, and dairy integrate more smoothly, ensuring an even crumb and creamy frosting.
-
Don’t Overmix: Once you combine dry and wet ingredients, mix only until just combined. Overmixing leads to tough cupcakes.
-
Accurate Measurements: Use a kitchen scale for best results, especially with flour and confectioners’ sugar.
-
Candy Bar Prep: Chop Butterfinger bars just before folding in; exposure to air can make them sticky.
-
Frosting Consistency: If frosting seems too stiff, add more milk, a teaspoon at a time. If too loose, add more powdered sugar.
-
Prevent Soggy Cupcakes: Allow to cool completely before storing or frosting, as residual steam can make cakes gummy.
Serving Suggestions
Creative presentation and pairing can elevate your Butterfinger Cupcakes from tasty to show-stopping.
-
Display cupcakes on a decorative cake stand or platter for celebrations.
-
Pair with cold milk, iced coffee, or even a peanut butter stout for adults.
-
For dessert bars or parties, offer a variety of toppings—mini Butterfingers, chocolate chips, or caramel drizzle.
-
Add a swirl of chocolate ganache under the frosting for extra decadence.
-
For themed events, use colored cupcake liners and edible gold dust for a luxurious touch.
