You might ask yourself what a dump cake is and how it gained that name!
What is a Dump Cake?
A dump cake is an easy dessert in which you simply “dump” all the ingredients into a baking dish without much mixing. Usually, it involves fruit or pie filling, a dry cake mix, and melted butter. The result is a delicious, cobbler-like treat with minimal effort.
Where did it originate?
Dump cakes are thought to have started in the U.S., probably around the 1950s or 60s. They became a hit because they’re super easy to make – you dump all the ingredients into a baking dish and bake. Perfect for busy home cooks, especially during the era when convenience was king!
What is the difference between a dump cake and a cobbler?
A dump cake and a cobbler are quite similar, but the main difference is in how they’re made. A dump cake is super easy—just dump all the ingredients into a dish and bake, usually with a cake mix on top. A cobbler typically has a biscuit or pie crust topping, and the ingredients are more carefully layered or mixed together.
Ingredients You’ll Need
- Lemon Curd: Adds a rich, tangy lemon flavor and a creamy texture to the cake. Use either homemade lemon curd or store-bought.
- Lemon Cake Mix: Provides the cake base and structure, making it fluffy and moist. Feel free to swap it for white, vanilla, or French vanilla cake mix.
- Butter: Melts into the cake mix, creating a golden, crispy topping and adding richness.
How to Make a Lemon Dump Cake
Step 1 – Preheat Oven and Prepare Dish
- Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius).
- Grease your 8 x 8-inch baking dish lightly with butter or non-stick spray.
Step 2 – Layer the Lemon Curd
- Spread the lemon curd evenly across the bottom of the greased baking dish.
Step 3 – Add the Cake Mix
- Sprinkle the dry lemon cake mix evenly over the pie filling, trying to cover as much of it as possible.
Step 4 – Drizzle with Butter
- Melt the butter in a microwave-safe bowl or on the stovetop.
- Drizzle the melted butter evenly over the cake mix, covering as much of it as possible. This helps the cake mix absorb the butter, resulting in a better texture.
Step 5 – Bake
- Place the baking dish in the oven and bake for 35 minutes or until the top is golden brown and crispy.
Step 6 – Cool and Serve
- Allow the cake to cool slightly before serving. If desired, dust with powdered sugar or serve with a dollop of ice cream for a little extra sweetness and a nice finishing touch.

Lemon Curd
Ingredients
- 1 cup butter cold
- 1 cup sugar
- 3 eggs room temperature
- 1/4 cup lemon juice
- zest of 2 lemons
Instructions
- Get all your ingredients ready.
- Thoroughly whisk eggs in a bowl.
- Add whisked eggs, sugar, lemon juice, and zest in a medium-size saucepan. Whisk ingredients thoroughly. Next, add the cubes of butter to the egg mixture. Note that the butter will melt eventually when cooking.
- Turn on the burner to the lowest heat setting and place water in a double boiler.
- Place the saucepan on the double boiler and constantly stir with a rubber spatula. The heat should be at the lowest setting. Make sure not to boil curd, or it will split. Stir with a spatula for 20 minutes.
- After 20 minutes, increase the heat to a low-medium flame. Stir constantly. The curd goes from a liquid yellow to an opaque creamy color in the last five minutes of cooking.
- Once it thickens, take off the stovetop and immediately transfer the cooked curd to a bowl. Make sure to keep stirring for a couple of minutes as it cools. If you get bits of scrambled egg, strain the curd or pluck out the bits of egg. The scrambled egg won't doesn't affect the flavor but just an aesthetic choice.
- This recipe makes 2 cups of lemon curd. Pour into a clean jar and place in the fridge once cooled. The lemon curd should last for about 1-2 weeks in the refrigerator.
