Ingredients You’ll Need
- 1 can (21 oz) lemon pie filling: This gives the cake its signature bright flavor and moisture. Opt for high-quality filling for the best taste.
- 1 box yellow cake mix: Adds the perfect sweetness and texture. Any brand will work, but go for a classic for the best results.
- 1/2 to 3/4 cup unsalted butter (sliced): This creates that deliciously crisp top layer. For a lighter option, you can use margarine, but the flavor won’t be the same.
How to Make Lemon Dump Cake
- Preheat the Oven: Set your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish to ensure easy removal of the cake later.
- Spread the Lemon Filling: Evenly spread the lemon pie filling across the bottom of the prepared baking dish, making sure to cover the surface.
- Add Cake Mix: Sprinkle the dry yellow cake mix over the lemon filling. Try to do this evenly without mixing; you’ll want the cake mix to be the top layer.
- Top with Butter: Place thin slices of unsalted butter evenly across the cake mix, covering as much of the surface as possible. This will help it crisp up beautifully while baking.
- Bake: Pop your dessert into the oven and bake for 40 to 45 minutes, or until the top is beautifully golden brown and slightly crisp at the edges. You’ll know it’s done when the cake feels set and is bubbling around the edges.
- Cool and Serve: Remove it from the oven and let it cool slightly, then scoop and enjoy while warm or at room temperature.
Storing & Reheating
Store any leftovers at room temperature for up to two days. To keep it fresh longer, transfer the cake to an airtight container and refrigerate for up to a week. If you want to store it longer, you can freeze it for up to three months. To reheat, place individual servings in the microwave for about 20–30 seconds or until warm. Keep in mind that the texture may change slightly after freezing, but a quick reheat can bring some of that original freshness back.
Chef’s Helpful Tips
- Avoid overmixing when layering the ingredients. The beauty of this dessert lies in its simple, unrefined assembly.
- Use room temperature butter for easier slicing, making sure to spread it evenly over the cake mix for optimal browning.
- Let the cake cool for about 15 minutes after baking. This will help it set up slightly, making it easier to serve.
- For additional flavor, consider mixing in some lemon zest into the lemon pie filling before layering.
- Feeling adventurous? You can substitute the lemon pie filling with blueberry or cherry pie filling for a twist on this classic.
Whether you’re hosting a gathering or just need a quick treat, this Lemon Dump Cake is bound to impress without straining your time or wallet.
