Ingredients of Frankenstein Rice Krispies

These Frankenstein Rice Krispies treats are perfect for any haloween party or celebration.  they’re a fun twist on a classic treat!
  • Rice Crispy (Rice Krispies Cereal): This is the base of your treat. The crunchy texture pairs perfectly with the gooey marshmallow mixture, creating that signature Rice Krispies treat consistency everyone loves.
  • Marshmallow: The marshmallows bring all the magic to this recipe. They melt down into a smooth, gooey mixture that binds the cereal together. Plus, they add that sweet, melt-in-your-mouth goodness.
  • Unsalted Butter: This helps the marshmallows melt smoothly and gives the treats that rich, buttery flavor. You can use salted butter if that’s what you have, but unsalted butter allows you to control the salt content better.
  • White Chocolate: For decorating your Frankenstein treats, white chocolate is perfect for creating eyes, bolts, or any other spooky details. The smooth texture of melted white chocolate makes it easy to pipe onto your Rice Krispies and gives a nice contrast against the green color.

  • Chocolate Sprinkle: These are great for adding some extra texture and decoration to your Frankenstein Rice Krispies hair. The sprinkle can resemble the creature’s bolts or add a bit of extra fun to the design.
  • Black Food Coloring: Use black food coloring to make additional details like eyebrows, stitches, or the outline of Frankenstein’s features. It helps bring your treats to life with spooky precision! Used to pipe on the “stitch” details to give your treats that final Frankenstein touch.

How to Make Frankenstein Rice Krispies

First, prepare the tray; Lay a piece of parchment paper at the bottom of a 20×20 cm tray and set it aside. This step ensures the Rice Krispies will be easy to remove after they’ve cooled.

In a medium-sized pot, add the marshmallows and butter. Melt the ingredients over medium heat, stirring constantly until the marshmallows are completely melted and smooth.

Once the marshmallows have melted, remove the pot from the heat. Immediately pour the Rice Krispies cereal into the pot, stirring well to coat each piece with the marshmallow mixture.

Then, quickly transfer the Rice Krispies mixture into the prepared tray. Use your hands (lightly greased or with parchment paper) to press the mixture evenly into the tray. Let it cool for 10-15 minutes or until the mixture is firm enough to cut.


In a separate pot, bring water to a boil. Set a heatproof bowl over the pot (bain-marie method) and melt the white chocolate, stirring occasionally. Once melted, remove the bowl from the heat. Take about 2 tablespoons of the melted white chocolate and mix it with black food coloring to create the “stitch” details.

Next, add green food coloring to the remaining white chocolate and stir until it’s well-mixed. Set both bowls aside to cool slightly.

Let’s decorate

Once the Frankenstein Rice Krispies mixture has cooled, cut it into 10 equal pieces. Dip about a third of each square into the green-colored white chocolate or spread the chocolate over the top with a spatula. Sprinkle chocolate sprinkles on top to mimic Frankenstein’s wild hair.

For the eyes, place eye-shaped candy onto each Rice Krispies treat. Then, use the melted black chocolate to pipe on stitches or outline Frankenstein’s features to give each treat its own unique look.

Finally, once the treats are fully set, it’s time to enjoy your spooky Frankenstein Rice Krispies! These are perfect for a Halloween party or just a fun treat to share with friends and family.
