Ingredients
With just a few simple ingredients, you’ll have all you need to make this lemon blueberry dump cake recipe.
See the recipe card below for the exact quantities of each ingredient.
- Canned Blueberry Pie Filling: We use canned because it is easier but if you enjoy making it homemade, that is a perfect way to personalize this dessert. I love using 3 cans for extra filling, but you can absolutely use 2 cans and still have a fantastic dessert.
- Box Lemon Cake Mix: Adds that bright citrus flavor.
- Butter, Unsalted: This is essential to give the cake mix its buttery, rich flavor and crunchy top. Salted butter works if that is all you have.
For this recipe, all you need is a 9x13 casserole dish and a spatula.
Substitutions and Variations
Love this lemon blueberry dump cake recipe but want to make it your own? Here are some fun ways to try it next time.
- Fruit Filling: Swap blueberry pie filling with cherry, apple, or mixed berry for a new twist. We love making a strawberry rhubarb dump cake.
- Box of Cake Mix: Try white, vanilla or yellow cake mix if you prefer a milder lemon flavor.
- Butter: Use melted butter and drizzle over the top for even coverage.
- Fresh Berries: Add a handful of fresh blueberries for extra texture and flavor.
- Topping: Sprinkle with chopped nuts or shredded coconut before baking for added crunch, or lemon zest for an extra citrus taste.
