Using a food processor, process cookies till they turn to crumbs. Add melted butter to the crumbs and use your hands to mix it in. Press cookie crumb mixture into a cookie sheet that has been lined with wax paper. Let chill over night. Once cookie crust is chilled, it is time to melt the chocolate. Place white chocolate in a bowl and dark chocolate in a separate bowl, put 1/2 cap full of oil in to each. Place both bowls (if they fit, if not start with the white chocolate) in the microwave and heat for 30 seconds at a time until melted , make sure to take them out and stir between each 30 seconds. The white chocolate may take a little longer to melt since there is more of it. Once the chocolates are done start with the white chocolate and pour it over the cookie mixture, I try to zig zag it up and down the pan, it makes it easier to spread. Then gently use the back of a spoon to evenly spread the white chocolate, you may have some crumbs get into the white chocolate and that is ok. Once the white chocolate is spread do the same with the dark chocolate, this spreads much easier than the white chocolate. After both chocolates are on then sprinkle with crushed candy canes. Let chill about 3-4 hours or until chocolate hardens. Once it has hardened you can break it into pieces. Store in the fridge.
