Crockpot Blueberry Lemon Dump Cake

What’s the most common mistake people make when cooking dump cake?

Although you’re required to mix the cake batter when making a traditional cake, you should never mix a dump cake. 

That’s because doing so will prevent your blueberry lemon dump cake from being crumbly on the outside and gooey on the inside, which is the desired texture that you can easily achieve if you layer the ingredients.

🥘 Ingredients

Lemon cake mix: When you’re out of lemon cake mix and can’t find it anywhere, you can use yellow cake mix as a substitute. Just add fresh lemon zest to the batter before you assemble the ingredients.

Blueberry pie filling: You can use fresh blueberries or frozen blueberries as alternatives to the blueberry pie filling. Just add some sugar and lemon juice to taste to mimic the flavor.

• Nutty-Crunch: Adding chopped nuts to the dump cake before cooking will provide a nutty flavor that compliments the blueberry lemon combo, and will also add a crunchy texture to the dump cake.
• Extra Crumbly Topping: Mix flour, sugar, and melted butter together to create a streusel that can serve as a crumbly topping for the dump cake. For that added flavor and texture, sprinkle the streusel on top of the dump cake before cooking it.

Now that you have all the necessary ingredients and tools, you can go ahead and make Blueberry Lemon Dump Cake from scratch. This dessert will probably be one of the easiest treats you will ever make!

Step 1: Prepare the crockpot using a non-stick cooking spray

Before anything else, you should spray the crockpot with cooking spray to avoid the dump cake from sticking and for easy cleanup.

Step 2: Dump the blueberry pie filling

Open the cans of blueberry pie filling and simply dump them at the bottom of the crockpot.

Step 3: Pour the lemon cake mix

After dumping the blueberry pie filling, pour the box of cake mix into the crockpot, and spread the cake mix evenly.
