3/4 c. butter, softened
1 c. sugar
1 egg
1 1/2 c. all-purpose flour
1/2 tsp. baking soda
1/4 tsp. salt
1/4 c. cocoa
1 tsp. vanilla
3/4 c. candy-coated chocolate pieces, divided (like M&M'S®)
1/2 c. chopped pecans, divided
1/4 c. flaked coconut
1/2 c. miniature marshmallows

Line a 12 inch pizza pan with heavy duty foil; grease foil and set aside.

Cream butter; gradually add sugar, beating well. Add egg and beat well.

Combine flour and next 3 ingredients; add to creamed mixture, mixing well. Add vanilla and mix well. Stir in 1/2 cup chocolate piece and 1/4 cup chopped pecans.

Spoon batter onto prepared pan, spreading to within 1 inch of edge. Sprinkle with coconut and remaining 1/4 cup pecans. Bake at 350 degrees for 15 minutes.

Sprinkle marshmallows and remaining 1/4 cup chocolate pieces on top; bake an additional 5 to 7 minutes. Cool on wire rack. To serve, cut in wedges.

(Also good made with Reese's Pieces instead of M&M'S®.)
