Total Time: 15 min
Servings: 16 treats


Ingredients:

  • 5 cups (132g) Rice Krispies cereal (or any crispy rice cereal)
  • ¼ cup (57g) unsalted butter
  • 1 (10-oz / 283g) bag mini marshmallows (about 8 cups)
  • Red food coloring (gel preferred)

Step-by-Step Instructions:

  1. Prepare your workspace , Line a baking sheet with parchment paper or a silicone mat. Set aside.
  2. Melt the magic , In a large saucepan over low heat, melt butter. Add marshmallows and stir until smooth and fully melted.
  3. Add creepy color , Stir in red food coloring until you get a light pink “brain” shade (remember, it’ll lighten when you add cereal).
  4. Mix it up , Remove from heat, pour in Rice Krispies, and stir until all pieces are coated.
  5. Shape the brains , Use a greased ice cream scoop or ¼ cup measure to portion out cereal mixture. Gently mold each mound into an oval shape with your hands.
  6. Add the “brain crease” Use the handle of a butter knife to create a central indent, then gently push the sides closer together for a realistic look.
  7. Paint on the gore , In a small bowl, mix a few drops of red food coloring with water. Use a clean paintbrush to streak “blood” across each brain.
  8. Cool & serve , Let set completely before serving. Store in an airtight container for up to 1 week.

Pro Tips:

  • Gel food coloring gives a richer color without adding too much liquid.
  • Lightly grease your hands before shaping to prevent sticking.
  • For an extra-scary touch, drizzle with red candy melts instead of food coloring.

❌ Learn From Mistakes:

One year I got a little too generous with the red coloring , the kids thought they were raw meatballs instead of brains. Keep it light for a fun, not frightening, effect!
