Blueberry Dump Cake is one of the easiest fruity desserts you've ever had. Dump all your ingredients in and bake! So easy and delicious too!
Preheat the oven to 350F degrees. Spray a 9x13-inch baking dish with nonstick cooking spray (I like the kind that has flour in it, like Baker’s Joy.)
Pour 2 cups frozen blueberries (thawed) into the baking dish then evenly sprinkle 2 Tablespoons packed brown sugar on top.
Then add the 21 ounce can blueberry pie filling and 1 teaspoon vanilla extract.
Gently mix to combine all the ingredients in the baking dish. .
Next, sprinkle the 15.25 ounce box white cake mix evenly over the blueberry mixture.
Place the ½ cup (1 stick) salted butter, cut into 20 slices. evenly over the cake mix. Don’t mix.
Bake for about 43 to 45 minutes or until the top is nice and golden.
Let cool for a few minutes. Then serve warm with whipped cream or a scoop of vanilla ice cream on top!
