Adjust the oven rack to the center position and preheat your oven to 350 degrees F.
Lightly grease only the bottom of a 9 x 13 baking dish. This cake needs to climb the sides of the pan to rise so don't grease them.
In a large bowl, add the full can of diced peached. Use a potato masher to mash the peaches into smaller bits. Carefully pour the Angel food cake mix into the peaches, and mix with a wooden spoon until fluffy.
Pour the batter evenly into the pan. Bake for 32-34 minutes. The top of the cake will be slightly cracked, fluffy, and golden brown.
Allow cake to cool for 15 minutes before slicing & enjoy! The center will slightly depress as it cools.
