At home, mix sugar and cinnamon and store in a zip-lock baggie. Don't forget to bring it with you camping.
At the campsite, stack the tortillas and wrap in a piece of foil; grill over indirect (med-low) heat, turning once, for about 5 minutes until they are warm and pliable.
Sprinkle 1/4 cup each of the chocolate chips and raspberries in the center of each tortilla; fold in the sides and roll up (like a typical burrito). Brush rolls with half of the melted butter. Grill burritos over indirect (med-low)heat, turning once, for about 3 minutes, until they start to show grill marks and the chocolate chips are melted.
Remove from heat and brush with remaining butter. Sprinkle with stored sugar and cinnamon mixture. Serve warm.
*These can be made at home on the grill too. They are great with a scoop of vanilla ice-cream. Kids love them!
