Separate cinnamon rolls and press into the bottom and up the sides of a standard muffin tin.
Cut up the apple pie filling into smaller pieces and fill each muffin tin.
Make crumbs by mixing the melted butter with the sugar and flour until crumbs form. Top each pie with the crumbs.
Bake 15-20 minutes or until crumbs are beginning to get golden brown.
Notes
You can eliminate the crumbs if you want to use the white icing that comes with the cinnamon rolls. Just cool the pies completely then drizzle with the icing.
