Ingredients Method Notes

Ingredients
  

  • 85 g unsalted butter or salted butter, omit extra salt
  • 6 cups marshmallows pink or white
  • 4 cups Rice Bubbles Rice Krispies
  • ½ teaspoon salt
  • Red food coloring
  • Optional: vegan marshmallows coconut oil, beetroot powder, Cocoa Krispies

Method
 

  1. Prepare a bain-marie by boiling water in a pot and placing a heatproof bowl on top.
  2. Melt butter and marshmallows in the bowl, whisking constantly until smooth.
  3. Remove from heat and whisk in salt and drops of red food coloring to create mottled appearance.
  4. Pour mixture over Rice Bubbles and mix quickly until coated.
  5. Oil hands, shape into oval brains (3–4 inches). Use knife to create a center groove.
  6. Dip toothpick in red coloring and draw vein patterns over each brain. Let cool completely before serving.

Notes

Pro tip: Work quickly once marshmallows are melted, as mixture sets fast. Oil hands generously to avoid sticking. Uneven coloring and lumpy shapes look more realistic. Avoid refrigerating—store in an airtight container at room temperature up to 3 days. For added effect, serve on black slate with dry ice or in specimen jars for a creepy presentation.
