How to Make It
Heat oven to 350 F. Add cookies to a food processor and process until finely crushed. Add 4 tablespoons melted butter and pulse again until moist crumbs form. Scrape crumbs into a 11” tart pan and press into an even layer covering the bottom and sides. Bake for 10 minutes, until crunchy and firm. Set aside to cool.
Make filling: Combine the cream cheese, 2 tablespoons softened butter, confectioners’ sugar, peanut butter, salt and ½ teaspoon vanilla in a large bowl. Beat with an electric mixer until light and fluffy. Scrape mixture into cooled tart shell and spread into an even layer. Transfer to freezer to chill for 10 minutes, until set.
Make chocolate ganache: Bring cream to a simmer in a small saucepan. Stir in the chocolate chips, ½ teaspoon vanilla, and corn syrup until smooth. Remove from heat and let cool slightly. Pour ganache over the chilled tart and spread until the surface is smooth and evenly covered. Let set briefly, about 5 minutes, then decorate surface with candy pieces. Transfer tart to freezer and chill until set, about 15 minutes.
