Lets prepare Crust first – Blend cookies in the food processor until fine crumble, then add melted butter and blend it again. Place ground mixture into buttered 9-inch baking pan then press into the bottom and sides evenly, I used a glass cup for that. Place in the fridge for at least one hour.
Pour into prepared piecrust and bake at 425F for 15 minutes. After 15 minutes reduce the heat to 350F (slightly cover the top of the pan with parchment paper or foil paper, it helps prevent the top from getting too dark) and bake for 50-55 minutes or until toothpick comes out clean when you insert it in the center.
