What I love about this Easy Halloween Treat Idea

  • Making one large Halloween Rice Krispies Treat means less time spent in the kitchen and still provides a wow factor that will be a big hit
  • You can’t go wrong with making rice krispies treats for the holidays. Kids, teens, and adults love this classic treat

Ingredients

Here’s what you’ll need for this easy Halloween dessert

  • Mini Marshmallows – You can use regular. I prefer mini because it is easier to melt tiny marshmallows and quicker. Don’t forget to reserve a couple for Frankenstein neck bolts
  • Butter – Use unsalted butter and be careful not to burn the butter on the stovetop. Watch it closely as it melts
  • Rice Krispies Cereal – You’ll use a good amount of cereal (around 6 cups), so it’s best to get a fresh new box
  • Food Coloring – You’ll want to color your melted marshmallows so it is close to the green you think of when you see Frankenstein
  • Frosting – Chocolate frosting is already dark brown which is perfect for this fun Halloween treat
  • Sprinkles – this is not completely necessary but I think it makes the hair look more like a hair texture
  • More marshmallows – You will only need one regular-sized marshmallow for the eyes
  • M&Ms – I used the Halloween green, but brown would also work well for this Frankenstein treat
  • Gel Decorating Gel – I used black for the pupil of Frank’s eyes

Equipment You’ll Need

  • A 9×13 baking dish to mold this treat
  • Parchment paper
  • A piping bag, coupler, and writing tips for making the stitches and eyebrows (you could also use a larger round tip for a bigger impact)

When the frosting has had time to dry and harden, you can transfer Frank onto a tray and cut the large rice krispies treat into smaller rectangles

Expert Tips

  • Watch your butter so it does not burn. I’ve had to scrap butter and start over so many times
  • Also, watch your marshmallows so they don’t burn. Turn the heat off if it is getting too hot and just stir until the marshmallows melt
  • If your marshmallows cool off too quickly and won’t stir into the cereal, pop them into the microwave for about 10 seconds

Variations

You can cut the large rectangle into about 20 smaller ones and decorate them individually

Instead of marshmallow bolts, you can use the tips of large pretzel rods for bolts or Rolos candy

Use melting chocolate instead of frosting for decorating

What to Serve with this Halloween Fun Food

  • Other Halloween Desserts like Halloween Marshmallow Pops, or Halloween Pretzel Bites
  • Hot chocolate is the perfect drink to pair with this fun treat
  • Apple Cider
  • Crescent Roll Witch Hats
  • Mummy Hot Dogs

What are some creative ideas to make a Halloween Treat look like Frankenstein?

Use marshmallows for eyes with M&M pupils or candy eyes. Add a stitched mouth and an angled stitch on his forehead. Add frosting for hair and chocolate sprinkles to create a hair texture. Use a large pretzel rod for the bolts in Frank’s neck. Angle his chocolate eyebrows to create different expressions
