How to Make Peach Cobbler Dump Cake

Step 1 - Prep the pan and oven: Preheat your oven to 350 degrees F. Lightly spray a 9x13 inch baking dish with nonstick cooking spray. A metal pan gives the best browning on the edges and bottom, but glass or ceramic works well — expect five to eight additional minutes of bake time with glass since it heats more slowly than metal and takes longer to drive the golden browning on the topping surface.

Step 2 - Add the peach layer: Open both cans of peach pie filling and spread them evenly across the bottom of the prepared baking dish. If the filling contains large peach slices, use a spoon to spread and distribute them so every section of the pan has a roughly equal amount of fruit and sauce. The peach layer should cover the entire bottom of the pan in a thick, even layer with no bare spots visible through the fruit.

Step 3 - Add the dry cake mix: Open the box of yellow cake mix and sprinkle the entire contents evenly over the peach layer. Do not stir, do not mix, and do not add any of the ingredients listed on the cake box — the only thing going into the pan is the dry powder. Spread the mix gently with a spoon or your fingers to create an even, unbroken blanket over the peaches. Any bare patches will not brown properly; any thick mounds will stay chalky in the center.

Step 4 - Lay the butter pats: Slice the cold butter into thin pieces approximately one quarter inch thick and lay them across the surface of the dry cake mix in a grid pattern, covering as much of the surface as possible. The goal is maximum coverage — the more of the cake mix surface touched by butter, the more evenly the topping will brown. Any dry patches of cake mix not covered by butter will absorb juice from below but will not brown on top, which produces the softer, more cobbler-like texture rather than the crispier golden crust that well-buttered sections develop.

Step 5 - Bake and serve: Bake uncovered at 350 degrees F for 45 to 55 minutes, until the top is deeply golden brown, the edges are visibly bubbling, and the surface feels set and dry rather than wet or loose when you tilt the pan slightly. The bubbling should be active around the perimeter — if only the very edges are bubbling and the center looks pale and still, give it another five minutes. Remove from the oven and cool for at least ten minutes before serving — the fruit layer is extremely hot directly out of the oven and needs time to settle and thicken slightly before spooning. Serve warm with vanilla ice cream or whipped cream.
