  • 1 box Betty Crocker™  brownie mix – pick your favorite flavor (Water, vegetable oil and eggs called for on brownie mix box)
  • 1 1/4 cups Betty Crocker™ Rich & Creamy creamy white frosting
  • 16 large marshmallows
  • Black decorating gel tube


  1. Pre-heat oven and combine brownie mix per instructions on the box.
  2. 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 30-45 minutes. 
  3. Remove from pan by lifting foil; peel foil away. For brownies, cut into 4 rows by 4 rows.
  4. Heat frosting in microwavable bowl uncovered on High 30 seconds, stirring every 10 seconds, until frosting can be stirred smooth and fluid. Do not overheat or it will become to runny!.  If frosting becomes too firm while decorating, microwave 5 seconds; stir.ghost-prep
  5. 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.
  6. Use black gel to make eyes and mouths.   Personal tip:  place the tub of gel in the freezer about 5 minutes before using.  This keeps the gel from running down the face of the ghost.
