To help with cleanup afterwards, the first thing you’ll want to do is to take some heavy duty aluminum foil and line your Dutch oven with it.
Take the cans of cherry filling and our into the Dutch oven, spreading the filling all over the bottom.
Mix the flour, oatmeal, and sugar in a bowl.
Add the vanilla.
Cut up the butter into 1 tbsp pieces and mix into the flour and sugar mixture. A pastry cutter works well.
Spread the topping on top of the cherries.
Put lid on Dutch oven and put 15 coals on top, 9 underneath (adjust for wind and temp) and cook for 60 minutes, or until cherry filling is bubbling up through the crust and crust is browning.
Remove, and serve with whipped cream.
