Place your leftover cookies into a food processor and ground into crumbs.

Combine: 2 cups cookie crumbs + 6 tbsp melted butter (if it's a soft and chewy cookie, use 4 tbsp butter instead of the above proportions)

Press into 9-inch pie plate with your fingers. Or make into mini pies by pressing them into greased large muffin tins.
