What is a Dump Cake?
Dump cakes are classic American desserts known for their simplicity: you literally “dump” ingredients into a baking pan—usually starting with some kind of fruit or sweet base, then dry cake mix, then butter—and let the oven do the work. For this Funfetti version, the process is even simpler, relying on boxed cake mix, sweetened condensed milk, and a generous shower of sprinkles to create a moist, gooey, party-ready cake with no fuss.
Origins of Dump Cake
Dump cakes became popular in the mid-20th century when convenience foods like canned fruit and boxed cake mixes were gaining traction. The idea was to make homemade baking accessible to all, especially for hosts who wanted quick, delicious results for large groups.
Ingredients Breakdown
Here’s what you’ll need to make Funfetti Dump Cake. You likely have most of these in your pantry already:
- 1 box Funfetti cake mix – The iconic sprinkle-blasted mix is at the heart of this easy dessert. Substitute with vanilla or yellow cake mix if desired.
- 1 can sweetened condensed milk – This adds creamy sweetness and richness to the cake without the need to mix up a batter.
- 1 container vanilla frosting – Provides a gooey layer that melts into the cake as it bakes. Classic vanilla frosting works best, but cream cheese or marshmallow fluff are delicious alternatives.
- 1 stick (1/2 cup) unsalted butter – Sliced thinly and placed over the top, this ensures a moist texture and helps the cake bake evenly.
- Rainbow sprinkles – Both mixed into the cake and for topping, sprinkles bring the signature Funfetti flair.
Optional Add-Ins: White chocolate chips, extra sprinkles, or fruit (such as strawberries) add even more fun and flavor.
Essential Equipment
- 9×13-inch baking dish – The standard pan size for dump cakes.
- Butter knife or spatula – For spreading frosting and sweetened condensed milk.
- Measuring cups – For measuring condensed milk and sprinkles.
Step-by-Step Instructions
Making Funfetti Dump Cake is almost as easy as eating it! Here’s how you build this festive treat:
- Preheat Your Oven
Set your oven to 350°F (175°C) to ensure even cooking. - Prepare the Baking Dish
Lightly grease the bottom of a 9×13-inch baking dish. This prevents sticking and makes serving easier. - Layer the Sweetened Condensed Milk
Pour the can of sweetened condensed milk into the baking dish. Use a spatula to spread it evenly. - Add the Frosting
Scoop dollops of vanilla frosting (about half the container) on top of the condensed milk. Spread gently—it doesn’t have to be perfectly smooth as it will melt in the oven. - Sprinkle with Rainbow Sprinkles
Scatter half the sprinkles over the frosting for pockets of color throughout the cake. - Add the Cake Mix
Evenly sprinkle the Funfetti cake mix over the entire surface, ensuring all wet ingredients are covered. - Top with Butter
Slice the stick of butter into thin pads and distribute across the cake mix layer. This helps to create the recognizable dump cake texture—crispy on top, gooey below. - Finish with More Sprinkles
Add the remaining sprinkles for a colorful crust. - Bake
Place in the oven and bake for 35-40 minutes, or until the top is golden and bubbly and the cake mix is mostly set (a few gooey patches are okay for extra indulgence!). - Cool and Serve
Let the cake cool for at least 15 minutes before serving. Serve warm or at room temperature—pairs wonderfully with vanilla ice cream.
