Ingredients Equipment Method Notes

Ingredients
  

For the Rice Krispies Treats
  • 3 tablespoons butter
  • 1 package marshmallows (10 oz)
  • 6 cups Rice Krispies cereal
For Decorating
  • 1/2 cup red candy melts for blood effect
  • 1/4 cup pink candy melts for brain texture

Equipment

  • Large saucepan
  • Spatula
  • 9x13 inch baking pan
  • Parchment paper
  • Knife

Method
 

  1. Grease a 9x13 inch baking pan with non-stick cooking spray or butter. Line with parchment paper, leaving an overhang on the sides.
  2. In a large saucepan, melt the butter over low heat.
  3. Add the marshmallows to the melted butter and stir until completely melted and smooth.
  4. Remove the saucepan from the heat.
  5. Add the Rice Krispies cereal to the marshmallow mixture and stir until well combined and coated.
  6. Press the mixture evenly into the prepared baking pan using a spatula greased with butter or non-stick spray.
  7. Let the mixture cool in the pan for at least 30 minutes, or until firm.
  8. Once cooled, use the parchment paper overhang to lift the Rice Krispies treat slab out of the pan.
  9. Using a knife, cut the slab into brain shapes. You can freehand this or use a stencil.
  10. Melt the red and pink candy melts separately according to package directions.
  11. Drizzle the red candy melts over the brain shapes to resemble blood. Use a toothpick to create a more realistic effect.
  12. Drizzle the pink candy melts in squiggly lines over the brains to create texture.
  13. Allow the candy melts to set before serving.

Notes

For a more gruesome look, you can add a few drops of red food coloring to the pink candy melts before drizzling.
