This Lemon Blueberry Dump Cake recipe combines sweet blueberries, tangy lemon curd, and a golden cake topping for a simple, flavorful dessert. With just a few pantry staples, it’s quick to prep and perfect for baking at home or over a campfire.
Spread blueberry pie filling evenly in the bottom of a Dutch oven. Spoon lemon curd over the top and gently swirl, leaving pockets of lemon throughout the filling.
Sprinkle the dry yellow cake mix evenly over the fruit layer. Do not stir.
Lay thin slices of butter evenly across the cake mix, covering as much surface as possible.
Slowly pour sparkling lemonade or lemon-lime soda evenly over the cake mix, pouring gently to avoid disturbing the layers. Do not mix.
Outdoor Camping Instructions
Place Dutch oven over hot coals with additional coals on the lid. Cook about 45 minutes, checking for doneness. If needed, cook up to 15 minutes longer until the top is golden and filling bubbles around the edges.
Indoor Oven Instructions
Bake uncovered at 350°F for 40–50 minutes until golden and bubbly.
Let cool slightly and serve warm, optionally topped with fresh blueberries or lemon zest.

Notes
Make sure the butter pats are spread evenly across the cake mix to create a golden, rich topping that bakes perfectly.
Slowly pour the sparkling lemonade over the cake mix to avoid creating holes, and so the topping stays even and tender.
Gently swirl the lemon curd into the blueberry pie filling without overmixing to get tangy bursts of flavor in every bite.
Let the cake sit for a few minutes after baking so the fruit thickens slightly and the slices hold together better.
