  • One 7.5oz jar of Marshmallow Fluff
  • ½ stick butter
  • 6-8 drops green food coloring
  • 5 cups rice krispies
  • 8 oz black or dark cocoa Wilton candy melts*
  • 16 candy eyes
  • 16 mini marshmallows
  • 9 to othpicks
  • *Note for the hair/mouth: If you can get your hands on black Wilton candy coating then use that. It is ALWAYS out of stock whenever I look, so I used the Wilton candy coating in Dark Cocoa and it worked just as well!


  • Grease and line an 8x8 inch square pan with a double layer of cling wrap.
  • Place marshmallow fluff and butter into a large saucepan over a low heat. Stir continuously until all the butter is melted and the mixture is smooth and well combined.
  • Add in the green food coloring a few drops at a time. Stir until you’re happy with the color.
  • Mix in the rice krispies, adding 1 cup at a time, until they are all coated in the green marshmallow mixture.
  • Tip the mixture into your prepared pan and press into an even layer with a spatula.
  • Leave to set for 30 minutes in the fridge.
  • Once chilled, transfer the krispie treats from the pan to a cutting board and cut into 2.5 x 2 inch rectangles.
  • Place a wire rack over kitchen paper and get ready to decorate!
  • Place the candy coating into a medium sized shallow bowl and place in the microwave in 30 second increments, stirring in between until all the coating is melted.
  • Take ¼ of the mixture and place in a small Ziploc bag. Leave to one side. Dip the top of each cut krispie treat into the bowl of melted candy coating. You want it to come ¼ - ½ inch of the way down the krispie treat; this is his hair line. Repeat with all of your krispie treats and then place them on the wire rack to set.
  • Use one of the toothpicks to place a little of the extra candy coating onto the back of your candy eyes and stick them to the front of your krispie treats, about ½ inch from the “hair”.
  • Snip a tiny hole into the end of your Ziploc bag and pipe a line ½ inch away from the candy eyes across the krispie treat. Then pipe a line perpendicular to the line across the treat at either end. Pipe two more along the line to create his mouth.
  • You can also pipe a zig zag line for his mouth, whichever you prefer.
  • Poke the remaining toothpicks through the side of each krispie treat in line with the mouth. Place a mini marshmallow on each end of the toothpick.
  • Repeat until all of your krispie treats are decorated, then leave to set for 20-25 minutes.
  • Frankenstein Rice Krispie Treats will keep in an airtight container, at room temperature for 3 days, or in the fridge for 5 days.
