Step-by-Step Instructions

Step 1: Prepare Your Baking Pans

Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper, then lightly grease the parchment. This double-protection method ensures your cake layers will release perfectly without sticking.

Step 2: Mix The Dry Ingredients

In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined. Make sure to break up any cocoa powder lumps for a smooth batter. Pro tip: sift the cocoa powder first if it’s particularly clumpy.

Step 3: Combine Wet Ingredients

In a separate bowl, beat the eggs slightly, then add buttermilk, vegetable oil, and vanilla extract. Whisk until smooth and well incorporated. The buttermilk is your secret weapon here – it adds incredible moisture and activates the baking soda for the perfect rise.

Step 4: Create The Cake Batter

Slowly incorporate the wet mixture into the bowl of dry ingredients while mixing at a low setting just until everything is incorporated. The batter will be quite thin – that’s exactly what you want for a moist cake.

Step 5: Bake The Cake Layers

Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs attached. Be careful not to overbake, as this can dry out your cake. Keep the cakes in their pans for a 10-minute rest period before carefully removing them to a cooling rack to finish cooling thoroughly.

Step 6: Prepare The Butterfinger Filling

In a medium bowl, combine the sweetened condensed milk and caramel sauce. Fold in the crushed Butterfinger pieces, saving some for the top. This filling will add incredible moisture and a surprise texture contrast in the middle of your cake.

Step 7: Make The Peanut Butter Frosting

In a large bowl, beat the softened butter and peanut butter until smooth and creamy, about 2 minutes. Incorporate the powdered sugar in stages, adding one cup and fully integrating it before introducing the next cup. Add the heavy cream, vanilla extract, and salt, then beat on medium-high speed for 3-4 minutes until light and fluffy. If the frosting seems too thick, add a tablespoon of heavy cream at a time until you reach the desired consistency.

Step 8: Assemble The Cake

Set your first cake round onto your chosen serving platform. Spread the Butterfinger filling evenly over the top, leaving about ½ inch border around the edge (this prevents spillage). Position the second cake round carefully on the filling, applying slight downward pressure to create a secure bond between layers.

Step 9: Frost And Decorate

Cover the entire cake with the peanut butter frosting, creating smooth sides and top. You can use an offset spatula for a rustic look or a bench scraper for perfectly smooth sides. Press the remaining crushed Butterfinger pieces onto the sides and top of the cake for decoration and that signature crunch.

Step 10: Chill And Serve

Refrigerate the cake for at least 30 minutes before serving to allow the flavors to meld and the frosting to set. For the best flavor and texture, remove from the refrigerator 15-20 minutes before serving to take the chill off.

Healthier Alternatives for the Recipe

While this butterfinger cake recipe is definitely an indulgent treat, here are some modifications to make it a bit lighter:

• Reduce Sugar: Cut the sugar in the cake by ¼ cup; the sweetness from the filling and frosting will still provide plenty of flavor.
• Lighten the Frosting: Use ½ cup Greek yogurt and ½ cup peanut butter instead of the full cup of peanut butter for a protein boost and less fat.
• Whole Wheat Option: Replace half the all-purpose flour with white whole wheat flour for added fiber.
• Single Layer Version: Make a single-layer cake with a light drizzle of caramel and a sprinkle of crushed Butterfingers to significantly reduce calories per serving.
• Portion Control: Bake in a 9×13 pan and cut into 24 squares instead of 12 slices for smaller portions that still satisfy the sweet tooth.

Serving Suggestions

• Serve slightly warm with a scoop of vanilla ice cream for an extra-decadent dessert experience.
• Add a drizzle of warm chocolate sauce over each slice just before serving for an impressive presentation.
• Pair with fresh berries on the side to balance the richness with some natural acidity.
• For coffee lovers, serve with a shot of espresso for a perfect flavor pairing – the bitterness of coffee highlights the chocolate and peanut butter notes.
• Create a dessert bar by serving small slices alongside other miniature treats for parties or special occasions.

Common Mistakes to Avoid

• Overbeating the Batter: Mix just until ingredients are combined to avoid a tough, dense cake. Statistics show that overmixing is the number one cause of failed homemade cakes, increasing density by up to 30%.
• Opening the Oven Door Too Early: This can cause your cake to sink in the middle. Wait until at least 25 minutes have passed before checking doneness.
• Using Cold Ingredients: Room temperature eggs, buttermilk, and butter incorporate much better and create a more uniform texture. Cold ingredients can lead to uneven baking and clumping.
• Skipping the Cooling Time: Frosting a warm cake will result in melted, runny frosting. Patience here makes all the difference in presentation.
• Cutting Immediately After Baking: Allow the cake to set for proper slicing – cutting too soon can result in a messy presentation and uneven pieces.

Storing Tips for the Recipe

• Fresh Enjoyment: This butterfinger cake recipe is best enjoyed within 3-4 days of baking for optimal freshness and flavor.
• Refrigeration: Store covered in the refrigerator, as the peanut butter frosting can soften at room temperature. Use a cake container or cover loosely with plastic wrap, being careful not to smash the frosting.
• Freezing Option: The unfrosted cake layers can be frozen for up to 2 months. Wrap each layer individually in plastic wrap, then aluminum foil. Thaw overnight in the refrigerator before assembling.
• Make-Ahead Components: The frosting can be made 1-2 days ahead and stored in the refrigerator. Bring to room temperature and re-whip before using.
• Sliced Storage: Individual slices can be stored in airtight containers, making them perfect for grab-and-go treats throughout the week.

FAQs

Q: Can I make this butterfinger cake recipe a day ahead?
A: Absolutely! In fact, many bakers find the flavors meld and improve after 24 hours in the refrigerator. Just be sure to keep it covered to prevent it from drying out.

Q: Can I use a cake mix instead of making the cake from scratch?
A: Yes, you can use a chocolate cake mix as a shortcut. Simply prepare according to package directions, then follow the instructions for the filling, frosting, and assembly.

Q: How do I prevent the crushed Butterfingers from getting soggy?
A: For the best texture, add the crushed Butterfingers to the outside of the cake shortly before serving, or at most a few hours ahead. The candy will gradually soften as it sits in the frosting.

Q: Would this recipe work well as individual cupcakes?
A: Definitely! This recipe adapts wonderfully to a cupcake format. Fill liners about two-thirds full, reduce baking time to 18-22 minutes, hollow out centers for filling, and finish with frosting and Butterfinger pieces on top.

Q: Is there a non-coffee option for the hot liquid in the cake batter?
A: Yes, you can substitute hot water or hot chocolate instead. The coffee doesn’t add a coffee flavor but enhances the chocolate. However, hot water works fine if you prefer to avoid caffeine.

Q: How finely should I crush the Butterfinger bars?
A: For the filling, crush them fairly fine for a consistent texture. For the decoration, a mix of fine crumbs and small chunks creates visual interest and varied texture in every bite.
