Why You’ll Love This Recipe

It’s the ultimate “dump-and-bake” wonder: just layer, drizzle, and walk away. The lemon cake mix adds a sunny zing that cuts through the sweetness of the pie filling, while the extra blueberries (fresh or frozen!) give it a rustic, fruit-forward soul. Baking in two smaller dishes means you can serve one now and freeze the other—or gift one to a neighbor with zero extra effort. And with only four ingredients (plus butter!), it’s pantry-friendly, budget-smart, and foolproof.

Summer gatherings and backyard BBQs

Church suppers or community potlucks
