Ingredients
20 Butterfinger Fun Size Bars (from the iconic bright yellow bag with blue lettering)
Butterfinger Fun Size Bars are the main flavor of this dump cake. They create a crispy, flaky, peanut-buttery candy layer at the bottom of the baking dish. As the cake bakes, the candy softens and melts slightly, giving the dessert its signature crunchy-gooey texture. The Butterfinger pieces also add a bold orange candy center that pairs beautifully with the butterscotch morsels.
1 (15.25 oz) box Duncan Hines Signature Yellow Cake Mix (classic red banner box)
Duncan Hines Signature Yellow Cake Mix forms the golden topping of the dump cake. Since the mix is sprinkled on dry, it absorbs moisture from the butter and melted candy as it bakes. This creates a buttery crust on top with tender, cake-like sections underneath. Yellow cake mix is a great choice because its vanilla flavor balances the intense sweetness of the candy.
1 cup (2 sticks) Land O Lakes Unsalted Butter (in the familiar yellow wrapper with the Indian Maiden)
Land O Lakes Unsalted Butter is essential for creating the rich, golden crust. Thin slices of butter are arranged over the dry cake mix so they melt slowly and evenly in the oven. As the butter melts, it moistens the cake mix and helps the top bake into a crisp, buttery layer. Unsalted butter lets the candy and butterscotch flavors stay front and center.
1 (11 oz) bag Nestle Toll House Butterscotch Artificially Flavored Morsels (yellow bag with the brown Toll House sign)
Nestle Toll House Butterscotch Artificially Flavored Morsels add smooth, sweet butterscotch flavor throughout the dessert. They fill the empty spaces between the Butterfinger bars and melt into rich pockets as the cake bakes. Their caramel-like flavor pairs perfectly with the peanut-buttery crunch of Butterfinger candy and the buttery yellow cake topping.
Step-by-Step Instructions
Step 1: Preheat the oven and prepare the baking dish
Preheat your oven to 350°F. While the oven heats, thoroughly grease a 9×13 Pyrex glass baking dish. Make sure to coat the bottom and sides well so the melted candy and butterscotch do not stick too much as they bake.
A glass baking dish works especially well for this recipe because it allows the candy layer to heat evenly. Since this dessert contains melted candy, greasing the dish generously is important for easier serving later.
Step 2: Arrange the Butterfinger layer
Unwrap all 20 Butterfinger Fun Size Bars. Arrange the unwrapped Butterfinger bars in an even layer on the bottom of the greased baking dish.
Try to cover the bottom as evenly as possible. The bars do not need to fit perfectly, but spacing them evenly helps make sure every scoop has some of that crisp, peanut-buttery Butterfinger center. This layer becomes the sweet candy foundation of the dump cake.
Step 3: Add the butterscotch morsels
Generously scatter the 1 (11 oz) bag Nestle Toll House Butterscotch Artificially Flavored Morsels into all the empty spaces around the Butterfinger bars.
Do your best to distribute the morsels evenly across the dish. They will melt into the candy layer and create gooey butterscotch pockets throughout the dessert. This step also helps fill gaps so the bottom layer has plenty of sweet, melted flavor in every section.
Step 4: Add the dry cake mix
Shower the dry 1 (15.25 oz) box Duncan Hines Signature Yellow Cake Mix evenly over the candy layer until it is completely buried.
Do not prepare the cake mix according to the box directions. For this dump cake, the mix stays dry when added to the dish. Sprinkle it gently and evenly over the Butterfinger and butterscotch layer. Use a spoon or clean hand to lightly level the surface if needed, but do not stir the layers together.
The dry cake mix will bake with the melted butter on top and the candy underneath, creating a buttery crust with gooey candy beneath it.
Step 5: Add the butter slices
Slice 1 cup (2 sticks) Land O Lakes Unsalted Butter into thin slices. Tightly shingle the thin slices of butter across the dry cake mix.
Try to cover as much of the cake mix surface as possible. The more evenly the butter is arranged, the more evenly the topping will bake. Gaps without butter may remain powdery, so take your time with this step. Overlapping the slices slightly helps create better coverage.
Step 6: Bake until golden and bubbling
Bake the dump cake at 350°F for 40-45 minutes.
The cake is ready when the top is golden, the crust looks set, and the edges are bubbling with melted butterscotch and candy. The golden crust may crack slightly, revealing the bubbling, melted butterscotch and the flaky, peanut-buttery orange core of the Butterfingers underneath.
Let the cake cool for a few minutes before serving. It will be very hot straight from the oven, especially the melted candy layer.
Tips for Best Results
Use a well-greased baking dish. Melted candy can become sticky as it bakes, so greasing the dish thoroughly makes serving much easier.
Slice the butter thinly. Thin butter slices melt more evenly across the dry cake mix. Thick chunks may leave dry patches in some spots and overly buttery areas in others.
Cover the dry mix as completely as possible with butter. This is one of the most important steps in dump cake baking. If you see large uncovered areas of cake mix before baking, add or shift butter slices to cover them better.
Do not stir the layers. Dump cakes work because the layers bake together in the oven. Stirring can change the texture and prevent the distinct candy bottom and buttery cake topping from forming properly.
Let it rest before serving. The filling will be extremely hot when it first comes out of the oven. A short cooling time helps the melted candy settle slightly and makes it easier to scoop.
Serve it warm for the best texture. The Butterfinger and butterscotch layers are softest and most gooey when warm. As the cake cools, the candy layer will firm up more.
Check near the end of baking. Since ovens can vary, start checking around 40 minutes. Look for a golden top and bubbling edges. If the center still looks too dry, continue baking for a few more minutes.
Serving Suggestions
Butterfinger Butterscotch Dump Cake is delicious served warm straight from the baking dish. Use a large spoon to scoop generous portions into bowls or dessert plates.
For an extra indulgent dessert, serve it with a scoop of vanilla ice cream. The cold ice cream melts into the warm cake and balances the rich candy flavor. Whipped cream is another simple topping that adds a lighter finish.
A drizzle of caramel sauce can make the butterscotch flavor even deeper. Chocolate syrup also works well if you want a candy-bar-inspired presentation.
For parties, serve this dump cake in small portions because it is rich and sweet. You can also sprinkle extra crushed Butterfinger pieces over the top before serving for added crunch and a fun bakery-style look.
This dessert is perfect for potlucks, game-day spreads, birthday parties, Halloween candy desserts, Thanksgiving dessert tables, Christmas gatherings, or casual weekend baking.
Storage and Reheating
Store leftover Butterfinger Butterscotch Dump Cake in an airtight container or cover the baking dish tightly with plastic wrap or foil.
Because this dessert contains melted candy and butter, it is best stored in the refrigerator after it cools. Refrigerate leftovers for up to 4 days.
To reheat individual servings, place a scoop in a microwave-safe bowl and warm it in short intervals until heated through. Start with 15-20 seconds, then add more time if needed. Be careful because the candy layer can become very hot.
To reheat a larger portion, cover the baking dish with foil and warm it in a 300°F oven until heated through. This method helps the topping stay closer to its original baked texture.
This dump cake is best enjoyed warm, but it can also be eaten chilled if you like a firmer candy-bar texture.
Variations and Add-Ins
For extra crunch, sprinkle chopped peanuts over the Butterfinger layer before adding the cake mix. This keeps the flavor close to the original recipe while adding more texture.
For a chocolate twist, add a handful of semi-sweet chocolate chips along with the butterscotch morsels. This creates a richer candy flavor without changing the main structure of the recipe.
For a caramel-style finish, drizzle caramel sauce over the cake after baking. Add it just before serving so the top stays attractive and glossy.
For more Butterfinger flavor, sprinkle crushed Butterfinger pieces over the top after baking. This adds a fresh crunchy candy texture.
For a party-style dessert, serve the warm dump cake in small cups with whipped cream and extra butterscotch morsels on top.
Frequently Asked Questions
Can I prepare this dump cake ahead of time?
Yes, you can assemble it a little ahead of time and bake it when ready. For the best texture, it is better to bake it fresh so the butter melts properly into the cake mix and the candy layer becomes warm and gooey.
Do I need to mix the cake mix with eggs, oil, or water?
No. Use the Duncan Hines Signature Yellow Cake Mix dry. Do not follow the cake box instructions for this recipe. The dry mix is sprinkled directly over the candy layer and baked with sliced butter on top.
Why are there dry spots on top of my dump cake?
Dry spots usually happen when parts of the cake mix are not covered with enough butter. To avoid this, slice the butter thinly and place the slices close together across the entire surface of the dry cake mix.
Can I use a metal baking pan instead of a Pyrex glass baking dish?
The original recipe calls for a 9×13 Pyrex glass baking dish. A metal pan may bake faster and can affect the texture of the candy layer. If using metal, watch the cake carefully near the end of baking.
How do I know when the dump cake is done?
It is done when the top is golden brown, the butter has melted into the cake mix, and the edges are bubbling with melted butterscotch and candy. The bake time should be 40-45 minutes at 350°F.
Should this be served warm or cold?
This dessert is best served warm because the Butterfinger and butterscotch layers are softer and gooier. However, leftovers can be refrigerated and reheated later.
Can I freeze Butterfinger Butterscotch Dump Cake?
You can freeze leftovers, but the texture may change because of the candy and buttery topping. For best results, enjoy it fresh or refrigerated within a few days.
