How to make cookie crumbs without a food processor

A food processor is the best tool when you need to make cookie or cracker crumbs for a dessert crust, whether you’re crushing graham crackers, oreos, gingersnaps, etc. But what if you don’t have a food processor?

Simply place whole cookies in a zip top plastic bag and crush with a rolling pin, mallet, or the bottom of a heavy glass. It will take some effort get them crushed enough and a uniform size, but it still works really well!
