Ingredients

• 2 cans (21 ounces each) blueberry pie filling
• 1 box (15.25 ounces) yellow or white cake mix
• 1 cup (2 sticks) unsalted butter, cut into thin slices
• 1 tablespoon fresh lemon zest

Equipment Needed

• 9×13 inch baking dish
• Rubber spatula
• Measuring spoons
• Knife and cutting board

How To Make

1. Preheat your oven to 350°F (175°C).
2. Pour both cans of blueberry pie filling into the 9×13 inch baking dish and spread them into an even layer using a rubber spatula.
3. Sprinkle the dry cake mix evenly over the layer of blueberry filling; do not mix it in, as the powder needs to sit on top to create the crust.
4. Distribute the thin slices of cold butter evenly across the surface of the dry cake mix, ensuring as much of the dry powder is covered as possible.
5. Sprinkle the fresh lemon zest over the top of the butter and cake mix.
6. Bake for 45 to 50 minutes, or until the top is golden brown and the fruit filling is bubbling vigorously around the edges.
7. Remove from the oven and let the dessert sit for at least 10 minutes before serving to allow the fruit layer to thicken slightly.

Expert Cooking Tips

• To ensure a crunchy topping, try to cover as much of the dry cake mix as possible with your butter slices. If you have dry patches remaining, add a few extra thin shavings of butter.
• If you prefer a more pronounced lemon flavor, stir two tablespoons of fresh lemon juice into the blueberry filling before adding the cake mix.
• Serve this dish warm with a scoop of vanilla bean ice cream or a dollop of unsweetened whipped cream to balance the sweetness.
• Store leftovers in an airtight container in the refrigerator for up to three days. Reheat individual portions in the microwave for 30 seconds to restore the warm, gooey texture.
• For added crunch, sprinkle half a cup of sliced almonds or chopped pecans over the butter before baking.

Frequently Asked Questions

Can I use lemon pie filling instead of blueberries?

You can certainly substitute one can of blueberry pie filling with lemon pie filling if you prefer a more intense citrus experience. However, using two cans of lemon filling might make the dessert overly tart, so consider keeping at least one can of berries for balance.

Do I need to mix the ingredients together?

No, the defining characteristic of this dessert is that you do not stir it. The layers must remain distinct so that the butter can melt through the dry cake mix to create a crisp, cobbler-style topping while the fruit stays moist underneath.

Can I make this ahead of time?

You can assemble the dish a few hours before baking and keep it in the refrigerator, but it is best to add the butter right before putting it in the oven. Baking it fresh ensures the crust remains crisp rather than becoming gummy.

Why is my cake mix still powdery on top?

If you see dry spots after the baking time is complete, it means there wasn’t enough butter covering those areas. You can gently press the dry spots into the bubbling fruit with a spoon, or simply add a few more small pats of butter and bake for an additional five minutes.

Conclusion

Preparing this dessert is an excellent way to enjoy a warm, homemade treat without the complexity of traditional baking. Because the ingredients are simple and readily available, you can easily adapt the flavor profile by adding spices like cinnamon or a splash of almond extract. If you find the result is too sweet for your taste, adding a squeeze of fresh lemon juice just before serving can brighten the flavors significantly.
