Ingredients
The simplicity of this 3-Ingredient Lemon Blueberry Dump Cake lies in its shortlist of ingredients. Using brand-name components ensures the best flavor balance and texture for your finished dessert.
- 2 (21 oz) cans of Duncan Hines Comstock Blueberry Pie Filling
- 1 box of Duncan Hines Lemon Supreme Cake Mix
- 1.5 sticks (3/4 cup) of Land O Lakes Unsalted Butter (sliced into very thin pats)
Notes and Substitutions
If you cannot find lemon cake mix, a yellow or white cake mix can be used, though you will lose that signature citrus punch. You can add the zest of one lemon to the blueberry filling to compensate for the change. While unsalted butter is preferred for the 3-Ingredient Lemon Blueberry Dump Cake to control the saltiness, salted butter works if that is all you have on hand.

Equipment
You will only need a few basic kitchen tools for this 3-Ingredient Lemon Blueberry Dump Cake. A standard 9x13-inch glass or ceramic baking dish is essential for the proper depth and even cooking. A sharp knife or a mandoline is helpful for slicing the butter into those critical thin pats. Lastly, a spatula is useful for spreading the pie filling into an even layer before adding the topping.
Instructions
Follow these simple steps to create your 3-Ingredient Lemon Blueberry Dump Cake.
- Step 1: Preheat your oven to 350°F (175°C) and lightly grease your 9x13 baking dish with non-stick spray or a little butter.
- Step 2: Dump both cans of the Duncan Hines blueberry pie filling into the prepared dish and use a spoon to spread them into one smooth, even layer across the bottom.
- Step 3: Sprinkle the entire box of dry lemon cake mix evenly over the blueberry filling. Use your hands or a spoon to level it out, but do not stir! The separation of layers is what creates the cobbler-like crust.
- Step 4: Cover every inch of the dry cake mix with the thin slices of butter. Try to avoid leaving large gaps of dry flour, as the butter is what hydrates the mix during the baking process.
- Step 5: Place the dish in the center of the oven and bake for 45-50 minutes. The 3-Ingredient Lemon Blueberry Dump Cake is finished when the top is golden and slightly firm, and the fruit is bubbling vigorously around the edges. Serve it warm for the best experience!
Pro Tips
To ensure your 3-Ingredient Lemon Blueberry Dump Cake comes out perfectly every time, focus on the butter distribution. Slicing the butter into very thin, almost translucent pats allows it to melt evenly into the flour. Some bakers prefer to melt the butter and pour it over the top, but thin slices often result in a superior, flaky crust. If you see dry spots of flour halfway through baking, quickly add a few more small pieces of butter to those areas. This small adjustment ensures your 3-Ingredient Lemon Blueberry Dump Cake has a consistent, delicious crumb without any chalky patches.
Serving, Storage & Variations
Serve your 3-Ingredient Lemon Blueberry Dump Cake warm with a generous scoop of vanilla bean ice cream or a dollop of whipped cream to complement the tart lemon. For storage, cover the dish tightly with plastic wrap and keep it in the refrigerator for up to four days. To reheat, a quick 30 seconds in the microwave will bring back that gooey, fresh-baked texture. For a fun variation, sprinkle half a cup of chopped walnuts or pecans over the butter layer before baking to add a nutty crunch that pairs beautifully with the blueberry filling.

FAQs
Can I use fresh blueberries instead of pie filling?
Yes, but you will need to toss them with sugar and a bit of cornstarch to achieve the same thick, bubbly consistency provided by the pie filling used in this 3-Ingredient Lemon Blueberry Dump Cake.
Why is my dump cake dry on top?
If your cake has dry spots, it is usually because the butter was not sliced thinly enough or distributed evenly. Ensure the butter covers all the dry cake mix before baking.
Does this dessert need to be refrigerated?
Yes, because of the fruit content, it is best to store any leftovers of your 3-Ingredient Lemon Blueberry Dump Cake in the refrigerator for up to 4 days.
