Preheat oven to 350°. Place almonds and coconut in a food processor; process until finely ground. Add flour and sugar; pulse to combine. Add butter; pulse until crumbly. Reserve 1-1/2 cups crumb mixture for topping. Press remaining mixture onto bottom and up sides of a greased 11-in. fluted tart pan with removable bottom.

For filling, place confectioners' sugar, 1/2 cup coconut, almond paste and extract in food processor; pulse until fine crumbs form. Add egg whites; process until blended. Spread into crust; sprinkle with reserved topping.

Bake 25-30 minutes or until golden brown. Sprinkle with remaining coconut; bake 5-8 minutes longer or until coconut is lightly browned. Cool completely on a wire rack. SHARE THIS RECIPE
