Preheat your oven to 350°F. Lightly coat a 9x13-inch baking dish with nonstick spray to prevent sticking.

Spread the peach pie filling evenly across the bottom of the prepared baking dish. If using canned peaches, drain them first and sprinkle in a little cinnamon and sugar for extra flavor.

In a medium bowl, stir together the dry yellow cake mix and 7-Up until just combined. The batter will be lumpy, which is perfectly fine! Avoid overmixing.

Pour the cake mix batter over the peaches, spreading gently to cover. Do not mix—this layering technique helps create the perfect cobbler texture.

Place the dish in the oven and bake for 45-60 minutes, or until the top is golden brown and a toothpick inserted in the cake comes out clean or with a few crumbs.

Let the cobbler cool slightly before serving. Enjoy warm with a scoop of vanilla ice cream or whipped cream for the best flavor!
