In a small bowl, combine flour and sugar; cut in butter until crumbly. Stir in the pecans. Press into a greased 13-in. x 9-in. baking dish. Bake at 325° for 20-25 minutes or until edges are lightly browned. Cool on a wire rack.
In a large bowl, beat cream cheese and confectioners' sugar until smooth; fold in 1 cup whipped topping. Spread over the crust.
In another large bowl, whisk the milk, extract and pudding mixes for 2 minutes; let stand for 2 minutes or until soft-set. Fold in 1-1/2 cups coconut. Spread over cream cheese mixture. Top with remaining whipped topping. Toast remaining coconut; sprinkle over top. Refrigerate overnight.
