We weren’t expecting this slow cooker lemon dump cake to be so good! It is amazing how good these three ingredients taste together. This warm lemon dessert is fun treat and easy to keep all the ingredients on hand for unexpected guests.

Ingredients for making lemon dump cake on a table.

Key Ingredients

Lemon Pie Filling: This is near cherry pie filling and pumpkin puree at the grocery store.

Yellow Cake Mix: You will need a box of yellow cake mix – but only use half, I find that this is the perfect amount for the pie filling and will set in the middle with no problem.

Butter: Use salted butter; it will cut the sweetness down and add depth of flavor.

How to Make Lemon Dump Cake

  1. Layer everything right in the crockpot- no mixing bowl, no extra steps.
  2. Cook until the top looks set and buttery and serve.

Tips & Variations

Crockpot Size Tip: A 6-quart oval is recommended. It has more surface area than a round slow cooker, ensuring an evenly cooked cake.

About the cake mix: You’re using half a box, which is perfect for keeping the topping from getting too thick. Measure it if needed, then seal the rest in a zip-top bag for next time.

Butter: Be sure to cut the butter cubes small and evenly distribute, the cake mix will be dry in spots otherwise.

Make it a little richer: Add a thin layer of cream cheese dollops (small spoonfuls) on top of the lemon filling before the cake mix.

Can I use a different filling with the same method?

You can swap the lemon for other flavors; just use 2 cans of pie filling. Cherry is a classic, and blackberry gives you a deeper berry flavor. For something brighter, try key lime (tangy and fun), or go with strawberry for a sweeter, lighter option. Everything else stays the same.
