Pour cherry pie filling into a small casserole dish. Stir in chocolate chips
In a medium sized bowl, mix together oats, sugar, flour and cocoa powder until combined. Cut butter into the oat mixture with a pastry cutter, two knives or your hands until crumbly, making sure to leave some bigger clumps as well.
Spoon oat mixture on top of the cherries. Bake at 350 degrees for 15-20 minutes, until set. Serve warm with ice cream or whipped cream on top.
