Preheat your oven to 400 and grease a 9x13 pan.
Add peaches and then sprinkle your cake mix over top. You want it well covered.
Next pour your soda over top slowly. Cover as much of the cake mix as possible. Do not mix! Just pour it over top
Bake for 45 minutes, and viola! A dessert fit for any company you invite, and no extra dishes to worry about!
