Ingredient List

  • Small check mark in a circle icon 1 bag Betty Crocker™ Fudge Brownie Mix
  • Small check mark in a circle icon Water, vegetable oil and egg called for on brownie mix box
  • Small check mark in a circle icon 1 cup Betty Crocker™ Rich & Creamy creamy white frosting (from 16-oz container)
  • Small check mark in a circle icon 16 large marshmallows
  • Small check mark in a circle icon Black decorating gel


  1. Heat oven to 350°F (325°F for dark or nonstick pan). Line 8- or 9-inch square pan with foil, allowing some to hang over edges of pan. Grease bottom and sides of foil with shortening or cooking spray. Make and bake brownies as directed on box for 8- or 9-inch square pan. Cool completely on cooling rack, about 1 1/2 hours. Freeze in pan 15 minutes. Using foil to lift, remove brownies from pan, and peel foil away. Cut into 4 rows by 4 rows.
  2. Heat frosting in microwavable bowl uncovered on High 20 to 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.
  3. 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 mouths.
