Line your camp dutch oven with parchment paper.
Pour the pie filling (aka the cans of peaches, syrup and all) into the bottom of the dutch oven and spread them out evenly.
Sprinkle the cake mix over the peaches, pressing it down gently to ensure it's evenly distributed.
Dust the top with ground cinnamon and brown sugar for an extra sweet touch.
Melt butter and drizzle it evenly over the cake mix. Be sure to cover the dry cake mix entirely.
Place the lid on the dutch oven and set it over hot coals. Add additional coals on top to create an oven-like environment.
Cooking time is about 50 minutes, or until the top is golden brown and the peaches are bubbly.
Scoop into bowls and, if you're feeling indulgent, top with whipped cream.
