This Red White & Blue Dump Cake is a ridiculously easy, festive Fourth of July dessert loaded with cherries, blueberries, and a buttery cake topping. Layer canned pie fillings, dry white cake mix, and melted butter, then bake until golden and bubbly.
Storage: Cover and keep at room temperature for up to 6 hours if serving the same day, or refrigerate for 3–4 days. For longer storage, freeze cooled portions for up to 2 months and thaw overnight in the refrigerator.
Reheating: Reheat in a 325°F oven for 10–15 minutes, covered with foil, then uncover for a few minutes to re-crisp the top. Individual servings can be microwaved for 30–45 seconds.
Tips: Don’t stir the dry cake mix into the fruit or the topping may become gummy. Make sure most of the cake mix is moistened by butter or fruit juices to avoid powdery spots. Use good-quality pie filling, and feel free to mix in a handful of fresh berries for brightness.
