Description

Delightfully spooky and fun, these Boo Brownies combine rich chocolate brownies topped with creamy white frosting and marshmallows decorated to look like ghostly faces. Perfect for Halloween or any festive occasion, they’re easy to make with a boxed brownie mix and simple decorating techniques.


Ingredients

Scale

Brownie Base

  • 1 box (16 oz) Betty Crocker™ Delights Supreme Original Brownie Mix
  • Water as called for on brownie mix box
  • Vegetable oil as called for on brownie mix box
  • Egg as called for on brownie mix box

Toppings

  • 1 cup from 1 tub (16 oz) Betty Crocker™ Rich & Creamy Creamy White Frosting
  • 16 large marshmallows
  • Betty Crocker™ black decorating gel (from 0.68-oz tube)


Instructions

  1. Prepare and bake brownies: Preheat oven to 350°F (325°F for dark or nonstick pan). Line an 8- or 9-inch square pan with foil, letting it hang over the edges. Grease the foil with shortening or cooking spray. Prepare brownie batter according to box instructions and pour into prepared pan. Bake as directed on the box for your pan size. Let cool completely on a cooling rack for about 1.5 hours. Freeze the brownies in the pan for 15 minutes to firm up.
  2. Cut and remove brownies: Lift brownies out of the pan using the foil overhang and peel the foil away. Cut the brownies into 16 equal pieces, arranged 4 rows by 4 rows.
  3. Prepare frosting: Place frosting in a microwavable bowl and heat uncovered on high for 20 to 30 seconds, stirring every 10 seconds until smooth and fluid. If it cools too much while decorating, microwave briefly for 5 seconds and stir.
  4. Decorate brownies: Place one large marshmallow on top of each brownie piece. Spoon about 1 tablespoon of warmed frosting over each marshmallow, fully coating it. Allow frosting to set for about 30 minutes.
  5. Add spooky faces: Use the black decorating gel to draw eyes and mouths on each frosted marshmallow to create ghostly faces, making your brownies spooky and fun.

Notes

  • Use a dark or nonstick pan for best browning results by adjusting temperature to 325°F.
  • Cooling the brownies completely before frosting helps prevent melting and mixing of flavors.
  • Freezing brownies for 15 minutes helps make cutting cleaner and easier.
  • If frosting becomes too thick while decorating, gently reheat to smooth consistency.
  • Decorating gel can be found in most baking aisles, perfect for detailed designs.
  • Store leftover brownies in an airtight container at room temperature or refrigerated.
