1. Stir together butter and egg in a large bowl. (Mixture will not fully blend together.) Stir in cookie mix and vanilla until a soft dough forms. Stir in toffee bits and almonds until well blended. Press mixture into a lightly greased 13- x 9-inch pan.
2. Bake at 350° for 25 to 30 minutes or until golden and a wooden pick inserted in center comes out clean. Cool in pan on a wire rack, and cut into bars.
Note: For testing purposes only, we used Betty Crocker Chocolate Chip Cookie Mix and Heath Toffee Bits.
