We use Chocolate cookie crust for many desserts.So I thought of sharing the crust recipe first.
About 6 nos chocolate cookies
6tspn melted butter

Preheat oven to 375°F.
Meanwhile crush the cookies into coarse pieces.

Bake for 10 minutes.
Now the cookie crust is ready

Combine this crumbs & butter in a bowl & mix well to a paste.
Firmly press this mixture in a pie plate (oven proof)
