1-First Step: Preheat the oven. Set oven to 375°F. Grease a 13×9-inch pan lightly with butter spray or oil. This prevents sticking and ensures easy serving. Heating the oven now lets you move fast on dumping layers. For high altitude, bump temp to 400°F and check 5 minutes early.

2-Second Step: Layer the peaches. Empty the 32-ounce can of peaches in heavy syrup into the pan bottom. Do not drain; syrup soaks into cake mix later. Cut peaches into bite-size chunks now for even texture. Spread evenly. This juicy base shines in summer or anytime with canned fruit. For fresh peaches, slice 5 cups and add 1/4 cup sugar.

3-Third Step: Add the dry cake mix. Pour the entire 18 1/4-ounce box of yellow cake mix over peaches. Cover completely without stirring. Press mix down firmly into syrup with a spoon or hands. Pressing helps it absorb juices for gooey results. White cake mix works too for milder taste. Gluten-free mix adapts here seamlessly.

4-Fourth Step: Top with butter. Cut 1/2 cup butter or margarine into small pieces. Place dots evenly across the top. For even coverage, melt butter and pour slowly, or grate frozen butter over. Cover all dry spots to avoid powdery patches. Vegan butter fits dietary needs perfectly.

5-Fifth Step: Sprinkle cinnamon. Dust cinnamon lightly over butter. Use 1-2 teaspoons or to taste. Extra spices like cloves boost flavor. Skip for plain version.

6-Final Step: Bake and serve. Bake 45 minutes until top turns golden and edges bubble. Center stays gooey. Cool 10 minutes. Serve warm with ice cream. Cuts into 10 servings. Broil 1-2 minutes for extra crisp if desired. Total time: 50 minutes ready. Pairs great with pumpkin cream cheese muffins for dessert spreads.
