Equipment

  • 9x13 inch baking pan
  • Large pot or Dutch oven
  • Mixing spoon or spatula
  • Parchment paper
  • Kitchen knife
  • Plastic Wrap
  • Baking Sheet
  • Measuring cups and spoons
  • Small bowls for decorations
  • Cooling rack (optional)

Ingredients
  

  • 6 cups Rice Krispies cereal
  • 10 oz marshmallows about 40 large
  • 4 tablespoons unsalted butter
  • Pink food coloring gel or liquid
  • Red food coloring gel or liquid
  • Red gel icing
  • Edible glitter optional
  • Candy eyeballs optional
  • Cooking spray for plastic wrap, optional

Instructions
 

  • Line a 9x13 inch baking pan with parchment paper.
  • In a large pot or Dutch oven, melt the butter over low heat.
  • Add the marshmallows and stir constantly until completely melted. Be patient and keep stirring to prevent burning.
  • Remove the pot from the heat.
  • Add the pink food coloring a few drops at a time, stirring until you reach your desired brainy pink hue. Add red food coloring to deepen the shade, if desired.
  • Add the Rice Krispies cereal and gently fold until evenly coated. Make sure all the cereal is coated with the marshmallow mixture.
  • Pour the Rice Krispies mixture into the prepared baking pan and press it down firmly and evenly.
  • Let the mixture cool slightly for about 10-15 minutes.
  • Once cooled slightly, gently cut out brain-sized portions using a kitchen knife (approximately 3x4 inches).
  • Cover your hands with plastic wrap. Lightly spray the plastic wrap with cooking spray for less sticking.
  • Shape each portion into a brain shape. Form two rounded lobes and a slight indentation down the middle.
  • Place the shaped brains on a parchment-lined baking sheet.
  • Use red gel icing to outline the brains, creating a vein-like effect.
  • Sprinkle a little edible glitter over the brains for an eerie shimmer, if desired.
  • Carefully place candy eyeballs on the brains, if desired.
  • Let the brains set completely for at least 30 minutes before serving.

Notes

For easier shaping, lightly wet your hands with water or coat them with a small amount of butter before shaping the brains to prevent sticking. Use fresh marshmallows for the best melting and texture. Store leftover Rice Krispies brains in an airtight container at room temperature for up to 3 days. Add a teaspoon of vanilla extract or almond extract to the marshmallow mixture for a flavor boost. Get creative with decorations using different colors of food coloring, sprinkles, or candies.
