Prep Time 15 minutes
Cook Time 3 minutes
Servings 20


  • 3/4 cup butter unsalted
  • 2 10- oz bags mini marshmallows
  • 1/2 tsp. vanilla extract
  • green food dye
  • 9-10 cups rice krispies
  • 1/2 cup melted chocolate [HAIR]
  • chocolate sprinkles optional
  • candy eyes
  • Pocky sticks usually in the Asian aisle at the grocery store (see photo above of packaging) [EYEBROWS]
  • black food gel see photo above [MOUTH]
  • rolos or mini peanut butter cups [BOLTS]


  1. Prepare a large casserole dish by greasing it and/or lining it with parchment paper.
  2. Place butter and marshmallows in a large microwave proof bowl and microwave for 1 minute. Continue to microwave until marshmallows have expanded to double their size. Remove and stir. Microwave longer if needed and continue to stir until smooth.

  3. Add vanilla extract and as much green dye as needed to get the color your want for your Frankensteins.
  4. Add rice krispies and stir. Pour into prepared pan and press flat using a buttered piece of parchment or your hands. Let cool.
  5. Cut into small rectangles.
  6. Dip the tops into melted chocolate (you can use candy Melts for this for chocolate chips with a little oithen palce on a piece of parchment to set. You can put them in the fridge to speed up the cooling. Add chocolate sprinkles if you want!
  7. Place on candy eyes (I used some melted chocolate as "glue" for everything), Pocky stick unibrows and rolos! Last, draw on mouths using your black food gel.

Recipe Notes

You can melt your butter and marshmallows over the stove OR in the microwave, I always prefer using the microwave because it's easier and faster for me.
