Ingredients

To make this quick lemon dump cake, you will need the following:

Ingredients to make lemon dump cake on the counter.
  • Canned lemon pie filling: The filling is the base of the dessert—choose a brand you enjoy for best flavor.
  • Boxed yellow cake mix: Yellow cake mix complements lemon nicely; you may also use white or vanilla mixes for a slightly different profile.
  • Cream cheese: An 8-ounce block, sliced into small pieces. The cream cheese adds creaminess and balances the lemon’s tartness.
  • Melted butter: One cup of unsalted butter, melted and poured over the cake mix to ensure it bakes into a crisp, golden topping.
  • Optional garnish: Whipped cream or vanilla ice cream are excellent for serving.

See the recipe card below for exact quantities and the step-by-step instructions.

Substitutions and Variations

Want to tweak the recipe? Here are a few simple swaps and ideas:

  • Homemade lemon curd or pie filling: Use your own lemon curd if you prefer a fresher lemon flavor.
  • Different cake mixes: Try lemon, vanilla, white, or French vanilla cake mix for subtle changes.
  • Alternative to cream cheese: If you don’t have cream cheese, small dollops of Greek yogurt or mascarpone can work; you may also omit it entirely for a lighter dessert.
  • Butter options: Butter slices can be used in place of fully melted butter, but pouring melted butter helps the dry cake mix hydrate evenly and prevents dry spots.

Equipment

You only need basic kitchen tools:

  • Cooking spray or butter for greasing the pan
  • Knife and cutting board for slicing cream cheese
  • 9 x 13-inch baking dish
  • Liquid measuring cup for melting and pouring the butter
  • Measuring cups and spoons

How to Make Lemon Dump Cake

Follow these simple steps to assemble and bake the lemon dump cake:

  1. Preheat the oven to 350°F (175°C). This temperature allows the cake topping to brown evenly while the filling bubbles gently.
  2. Prepare the baking dish by coating a 9×13 pan lightly with cooking spray or butter, making sure the corners are well greased.
  3. Spread the lemon pie filling evenly across the bottom of the pan, bringing it into each corner so every piece gets filling.
  4. Sprinkle half the cake mix over the lemon filling in a thin, even layer.
  5. Arrange the cream cheese slices evenly over the cake mix. Aim to space pieces so each serving will have some cream cheese.
  6. Add the remaining cake mix to cover the cream cheese. Gently shake the pan to level the topping and allow mix to fall into low spots.
  7. Pour the melted butter slowly and evenly over the top so the dry cake mix is moistened. Using a liquid measuring cup gives good control for even distribution.
  8. Bake for 50–55 minutes, until the top is golden brown and the filling is bubbling at the edges.
  9. Cool slightly on a rack for 10–15 minutes before serving. The cake can be served warm, at room temperature, or chilled.

How to Serve

Serve this lemon dump cake with a dollop of whipped cream or a scoop of vanilla ice cream for contrast between the warm, tart filling and cool topping. A light dusting of powdered sugar or a few fresh berries makes an attractive finish.

Storage

This dessert contains fruit, so keep it covered at room temperature on the first day only. After that, store it covered in the refrigerator for up to four days. Reheat individual servings briefly in the microwave if you prefer them warm.

Expert Tips and FAQs

Use these tips to get the best results:

  • Grease the dish well, especially the corners, to make serving easier.
  • Distribute the lemon filling evenly so every bite has flavor.
  • Shake the pan after adding the cake mix to even out the topping and avoid tall mounds that resist butter penetration.
  • Pour melted butter carefully and evenly; it will spread while baking, so full perfection isn’t required.
Can you make dump cakes ahead of time?

Yes. You can assemble the dessert in advance and refrigerate it until you’re ready to bake, or bake ahead and reheat gently before serving.

Why are they called “dump cakes”?

The name comes from the simple method of assembling the dessert—ingredients are essentially “dumped” into the pan and baked, with minimal mixing or prep.

What if the cake is powdery after baking?

If the top is powdery, it means the dry cake mix didn’t absorb enough moisture. Ensure the butter and filling are evenly distributed. If you notice dry spots while baking, spoon a little filling or melted butter onto those areas and return it to the oven for a few minutes.
