First, preheat the oven to 350° F.
In a medium mixing bowl, combine the brownie mix, rolled oats, chocolate chips, and melted butter together. The mix will look very dry and crumbly! It's perfect.
Then, in a greased 8x8 inch pan, pour the cherry pie filling directly to the bottom of the pan. Spread into an even layer.
Next, evenly sprinkle the crumble mixture on top of the cherry crumble.
Finally, bake this baby for 30-35 minutes or until the edges are bubbly!
Let cool for at least 10 minutes before serving! Enjoy with vanilla ice cream and whipped cream;) Keep any leftovers on the counter or fridge for up to 4 days!
