Preheat oven to 350 degrees F. Grease an 8x8-inch pan.
Using a food processor fitted with a metal blade (or use a pastry blender) combine flour, confectioner's sugar and butter. Pulse processor until mixture resembles coarse crumbs.
Reserve 1/3 of this mixture for the topping and set aside. Press remaining mixture in the bottom of the prepared pan.
Spread Fig & Walnut Butter over the crust.
Mix brown sugar into the topping. Crumble over fig and walnut filling.
Bake for 40-50 minutes, until golden brown. Let cool completely and cut into squares.
