What You’ll Need

These Frankenstein Rice Krispie Treats are surprisingly simple to make with just a handful of ingredients. Most of these items are probably already in your pantry!

• 4 ⅔ cups Rice Krispies: The crispy base of our monster treats.
• 10 ounces marshmallows (about 40 regular or 6 cups mini): The sticky, sweet element that holds it all together.
• 4 tablespoons European salted butter: Adds richness and flavor. You can also use regular salted butter.
• 1 cup royal icing: For piping Frankenstein’s features. For a shortcut, store-bought black cookie icing works wonderfully!
• Green food coloring (Americolor Soft Gel Paste Electric Green recommended): Gives Frankenstein his signature green hue.
• Black food coloring (Americolor Soft Gel Pate Super Black recommended): For darkening the royal icing. If using store-bought black icing, skip this ingredient.
• Candy eyes: For a spooky stare.
• Disposable decorating bag & size 2 tip (or a ziplock bag with a corner snipped): To pipe the icing details. Don’t have these? No problem! Store-bought icing tubes often have tips built-in.
• Square cookie cutter (2 to 2 ½-inch): For perfectly shaped treats. A sharp knife works too!

From Start to Finish

Here’s how to create these monstrously delightful treats:

Step 1: Prep the Krispies

Line your baking tray with parchment paper and lightly grease it with cooking spray. Pour the Rice Krispies into a large bowl and also give it a light coat of cooking spray. Set both aside.

Step 2: Melt the Marshmallows

In a microwave-safe bowl, combine the marshmallows and butter. Microwave in 30-second intervals, stirring after each, until melted and smooth. Avoid overheating. A few lumps are fine; the residual heat will smooth them out.

Step 3: Mix and Color

Stir in a few drops of green food coloring until you reach your desired shade of Frankenstein green. Then, pour the melted marshmallow mixture over the Rice Krispies. Mix well, ensuring all the cereal is coated.

Step 4: Mold the Treats

Transfer the mixture to the prepared baking tray. Using a spatula or lightly greased hands, press the mixture evenly to form a rectangle about ½-inch thick.

Step 5: Set and Cut

Let the treats set for 1-2 hours at room temperature, or chill in the refrigerator for about 30-45 minutes for quicker setting. Once set, use a square cookie cutter or a sharp knife to cut out individual squares.

Step 6: Decorate the Monsters

Prepare your royal icing (or use store-bought black icing). Fill a decorating bag or a ziplock bag with the black icing. Pipe hair onto each square, add candy eyes, and create a simple mouth and a scar. Let the icing dry completely before serving.

Test-Kitchen Tips

Here are a few helpful hints to ensure your Frankenstein Treats turn out perfectly:

• Microwave Magic: For melting the marshmallows, less is more. Start with short bursts in the microwave, stirring frequently, to prevent burning. Check out our tips for melting marshmallows for more guidance.
• Sticky Situation: If the Rice Krispie mixture is too sticky to handle, lightly grease your hands with cooking spray or butter before pressing it into the pan.
• Perfect Piping: For precise piping, use a decorating bag with a small tip. If you don’t have a decorating bag, a ziplock bag with a corner snipped off works in a pinch.
• Chill Out: If you’re short on time, chilling the treats in the refrigerator for about 30-45 minutes will help them set quickly.

Try These Variations

Want to put your own spin on these Frankenstein Treats?

• Chocolate Frankenstein: Add ½ cup of melted dark chocolate to the marshmallow mixture for a chocolatey twist. Drizzle some extra melted chocolate over the set treats for a creepy effect.
• Fruity Frankenstein: Incorporate dried cranberries or chopped gummy worms into the Rice Krispie mixture for a burst of color and flavor. These colorful additions create a playful, monster-mash feel.
• Mummy Treats: Skip the green food coloring and wrap strips of white melted chocolate or candy melts around the treats to create mummies. For more spooky inspiration, browse our Halloween recipes.
• Rainbow Monsters: Use different shades of food coloring to make a batch of colorful monsters. Let your imagination run wild with the possibilities! These are a perfect choice for parties that aren’t just Halloween.

How to Serve

• Party Platter: Arrange the treats on a spooky platter with other Halloween goodies. For a ghostly touch, try serving them with some white chocolate ghost cookies.
