DIRECTIONS

In a large mixing bowl, cream butter and brown sugar until light and fluffy. Beat in egg and vanilla. Combine the flour, baking soda and salt; add to the creamed mixture. Stir in oats.
    Press into a greased 15-in. x 10-in. x 1-in. baking pan. Bake at 350° for 10-15 minutes or until golden brown. Cool on a wire rack.
    In a microwave-safe bowl, melt caramels and water; stir until smooth. Spread over crust. Sprinkle with the chips, nuts and M&M's. Gently press into the caramel mixture. Melt confectionery coating; drizzle over the top. Let stand for 5 minutes or until coating is set. Cut into bars. Yield: 6 dozen. *Editor's Note: Confectionery coating, sometimes called "almond bark" or "candy coating", is found in the baking section of most grocery stores. It is often sold in bulk packages of 1 to 1-1/2 pounds.
