Turn a simple 9x9 inch brownie into a monster masterpiece by piping on green, orange, and purple frosting "hair" using a Wilton tip 233. Finish with royal icing eyes, bone sprinkles, and festive fondant for a Halloween dessert that's as fun to make as it is to eat.

Ingredients

Directions

  1. Begin with a 9x9 inch square brownie, whether store-bought, from a box mix, or homemade.
  2. Prepare or purchase 1.5 pounds of frosting, such as Italian meringue buttercream, marshmallow buttercream, or a store-bought variety.
  3. Divide the frosting equally among three separate bowls.
  4. Use food gel coloring to tint one bowl green, one orange, and one purple, adding drops until you achieve your desired shade.
  5. Spoon each colored frosting into its own piping bag fitted with a Wilton tip 233.
  6. Pipe the frosting onto the top of the brownie in a zigzag or spiral pattern, releasing pressure as you lift the bag away to create hair-like strands.
  7. Continue piping until the entire top of the brownie is completely covered with frosting.
  8. Finish by attaching royal icing eyes, bone-shaped sprinkles, and pieces of colored fondant or candy for an eerie decoration.
