Preparation Phase & Tools to Use

To bring the Butterfinger Bomb Cake to life, you’ll need the following tools:

• Stand or Hand Mixer: Essential for mixing the cake batter and whipping the cream to the perfect consistency.
• 9-Inch Round Cake Pans (2 or 3): These give the cake its layered structure. Non-stick pans or pans lined with parchment paper make removal much easier.
• Offset Spatula: This will help you spread the frosting and whipped topping smoothly between and over the layers.
• Mixing Bowls: Several bowls will come in handy for preparing the different components separately.
• Wire Rack: Use this for cooling your cakes evenly without soggy bottoms.
• Knife or Cake Leveler: Ensures each cake layer is even for a clean, bakery-style finish.

Preparation Tips

Let your cake layers cool completely before adding whipped cream or caramel; otherwise, everything will melt and slide. When crushing Butterfinger bars, aim for a mix of fine and chunky bits for better texture. If you’re short on time, a boxed devil’s food cake mix works beautifully—just make sure to follow the extra moist version directions. Finally, chill the assembled cake for at least an hour before serving to let the flavors meld and the layers firm up.

Ingredients for this Butterfinger Bomb Cake

• 1 box Devil’s Food cake mix (plus ingredients listed on the box: usually eggs, oil, and water)
• 1 cup sour cream (for extra moisture)
• 1 package (3.4 oz) instant chocolate pudding mix
• 1/2 cup vegetable oil
• 4 large eggs
• 1/2 cup milk
• 1 teaspoon vanilla extract
• 8 oz whipped topping (such as Cool Whip), thawed
• 1 jar (12 oz) caramel sauce
• 6 regular-sized Butterfinger candy bars, crushed (divided: 4 for layering, 2 for topping)
• 1 1/2 cups heavy cream (if making fresh whipped cream)
• 1/3 cup powdered sugar (for fresh whipped cream)
• Optional: chocolate ganache or melted chocolate for drizzling

Step 1: Prepare the Cake Layers

Preheat your oven to 350°F (175°C). Grease and flour two or three 9-inch round cake pans or line them with parchment paper circles. In a large mixing bowl, combine the cake mix, instant pudding mix, sour cream, oil, eggs, milk, and vanilla. Beat with a mixer on medium speed for 2-3 minutes until the batter is smooth and thick. Divide the batter evenly between the prepared pans and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer them to wire racks to cool completely.

Step 2: Make the Whipped Cream (If Not Using Store-Bought)

In a chilled mixing bowl, beat the heavy cream and powdered sugar together until stiff peaks form. Be careful not to over-whip. Set aside in the refrigerator until ready to use.

Step 3: Crush the Butterfingers

Place the Butterfinger bars in a zip-top bag and crush them using a rolling pin or a heavy skillet. You want a mix of fine crumbs and larger candy chunks for varied texture. Separate into two portions: one for the filling, one for topping.

Step 4: Assemble the Cake

Place one cake layer on a serving plate or cake board. Spread a layer of whipped topping over the cake, then drizzle with caramel sauce and sprinkle generously with crushed Butterfingers. Repeat this layering process with the remaining cake layers. Finish with a layer of whipped topping on the top and sides of the cake.

Step 5: Decorate the Top

Drizzle the top of the cake with more caramel sauce and melted chocolate or ganache. Add extra crushed Butterfinger chunks on top for a dramatic finish. For extra flair, you can pipe whipped cream around the edges.

Step 6: Chill Before Serving

Refrigerate the assembled cake for at least 1 hour, preferably longer, to allow the flavors to meld and the layers to set. This also makes slicing much easier and cleaner.

Notes

For the best flavor and texture, allow the Butterfinger Bomb Cake to rest in the refrigerator overnight. This not only lets the caramel soak into the cake layers slightly but also helps the whipped topping set firmly, making it easier to slice. When slicing, use a warm serrated knife to get cleaner cuts without dragging the toppings. You can customize the cake with chocolate chips, peanut butter drizzle, or even a chocolate mousse layer if you want to elevate it even more.

Watch Out for These Mistakes While Cooking

• Rushing the cooling process: Layering while the cake is still warm can lead to melting and sliding toppings.
• Over-whipping the cream: If making homemade whipped cream, avoid turning it into butter. Stop at stiff peaks.
• Using too much caramel between layers: It may seep out and make the cake soggy or hard to cut. Drizzle moderately.
• Skipping parchment or greasing: This can lead to broken cakes. Always prep your pans well.
• Not chilling before serving: This step helps everything firm up and creates a more cohesive slice.

Storage Instructions

Store any leftover Butterfinger Bomb Cake in the refrigerator, covered with plastic wrap or in an airtight container. It stays fresh for up to 4 days. For best results, avoid freezing, as whipped toppings and crushed candy bars don’t thaw well. If making in advance, prepare the cake layers ahead and assemble the day of serving to maintain texture.

Frequently Asked Questions

Can I make this cake ahead of time?

Yes! You can bake the cake layers a day or two in advance. Assemble the cake on the day you plan to serve it for the freshest texture.

What if I can’t find Butterfinger bars?

You can substitute with other peanut butter and chocolate candies like Reese’s, but the distinct crunch of Butterfinger may be missed.

Can I use boxed whipped topping instead of homemade?

Absolutely. Store-bought whipped topping works just as well and can save time.

Is there a gluten-free version?

You can use a gluten-free chocolate cake mix and ensure all other ingredients (especially candy bars) are gluten-free.

Can I freeze Butterfinger Bomb Cake?

It’s not recommended due to the whipped topping and candy texture changes during freezing and thawing.

How do I get clean cake slices?

Use a sharp, serrated knife dipped in hot water. Wipe between each cut for the cleanest presentation.

Can I use caramel bits instead of sauce?

Caramel bits won’t give the same smooth layering. Stick to a drizzle-style sauce for the best effect.

How can I make this more decadent?

Add a layer of chocolate ganache between the cake and whipped topping or top with chocolate curls.
