What you’ll need:
1 box of Betty Crocker Original Supreme Premium brownie mix
(Water, vegetable oil and eggs called for on brownie mix box)…
1 1/4 cups Betty Crocker Rich & Creamy creamy white frosting (from 16-oz container)
16 large marshmallows
black decorating gel (from 0.68-oz tube)
Heat oven to 350°F (325°F for dark or nonstick pan). Line 8- or 9-inch square pan with foil so foil extends about 2 inches over sides of pan. Spray foil with cooking spray. Make brownies as directed on box for 8- or 9-inch square pan. Cool completely, about 1 1/2 hours. Remove brownies from pan by lifting foil; remove foil. For 16 brownies, cut into 4 rows by 4 rows.
Heat frosting in microwavable bowl uncovered on High 30 seconds, stirring every 10 seconds, until frosting can be stirred smooth and fluid. If frosting becomes too firm while decorating, microwave 5 seconds; stir.
Top each brownie with 1 large marshmallow. Spoon 1 tablespoon frosting over each marshmallow to coat. Let stand until frosting is set, about 30 minutes. Use black gel to make eyes and mouth.
