Back in the '80s, cherry dump cakes were a fixture at church potlucks and family dinners-one of those simple desserts that earned a spot in every home cook's rotation. The name made us laugh as kids, but the recipe stuck around because it was just about the easiest cake recipe anyone could make.
When I married my husband in 2000, I swapped cherries for blueberries-he's never met a blueberry dessert he didn't like. I started using blueberry pie filling for that rich, sweet flavor and added crushed pineapple for brightness. Over time, I threw in almond extract, a little lemon zest, and some slivered almonds on top of the cake mix for crunch. This delicious blueberry dump cake recipe is my go-to for feeding a crowd or satisfying a sweet tooth with minimal effort.
Easy dump cake recipes have been around since mid-century, built for busy cooks who wanted simple recipes with maximum payoff. My blueberry version takes that convenience and makes it shine-whether you use lemon cake mix, a classic box of cake mix, or stick with yellow cake mix, the results are a golden, bubbling decadent dessert that tastes far more impressive than the effort it takes.

- Large Mixing Bowl - For combining filling
