Frankenstein Rice Krispies Treats – fun Halloween snack for kids

Alright, confess—I absolutely love Halloween snacks that are as much fun to make as they are to eat! These Frankenstein Rice Krispies Treats are a perfect example. Imagine gooey marshmallows and crispy cereal coming together in a bright green Frankenstein shape, complete with little candy eyes and a bolt-like smile. The kids think they’re spooky, but secretly, they’re just craving that irresistible, chewy crunch. Plus, they’re so simple to whip up, even if your marshmallows threaten to stick to everything (been there, done that!). I can’t wait to show you how to make these playful treats that will bring a little monster-sized fun to your Halloween party or school event.

Quick Facts

• Yield: Makes about 12 Frankenstein treats
• Prep Time: 15 minutes
• Cook Time: 5 minutes
• Total Time: 20 minutes

Ingredients

For the Main Dish:

• 6 cups Rice Krispies cereal
• 10 oz (about 40) marshmallows
• 3 tbsp unsalted butter
• 1 tsp vanilla extract
• Green food coloring (gel or liquid)

For the Decoration:

• Mini candy eyes
• Black icing or edible marker
• Black licorice strings (for “bolts”)

How I Make It

Step 1:

First, melt butter in a large saucepan over low heat. Once melted, toss in all the marshmallows and stir continuously until smooth and gooey. This is where patience pays off—marshmallows can be stubborn, so keep the heat low to prevent scorching!

Step 2:

Once melted, remove from heat and add vanilla extract and a few drops of green food coloring. Stir until you get a vibrant green color. Add more coloring if you want that Frankenstein green to really pop.

Step 3:

Pour the marshmallow mixture over the Rice Krispies in a large bowl. Use a buttered spatula or clean hands to gently fold and mix everything together—be careful not to squash the cereal too much, or it’ll lose its crunch.

Step 4:

Press the mixture evenly into a buttered 9×13-inch pan. Pat it down firmly so the treats hold their shape, but don’t press so hard that it gets dense and tough.

Step 5:

Let the mixture sit at room temperature for about 30 minutes to set, then cut into rectangles. Now comes the fun part—shape each rectangle into Frankenstein’s head by squaring the edges.

Step 6:

Decorate! Stick on mini candy eyes and use black icing or an edible marker to draw a stitched smile. Add little pieces of black licorice on the sides as “bolts.” Voilà—creepy-cute Frankensteins ready to eat!

Variations & Tips

• Use marshmallow cream instead of whole marshmallows if you’re short on time—just melt with butter the same way.
• Add some crushed pretzels inside for a salty crunch surprise.
• If green food coloring makes the marshmallows slightly runny, add an extra cup of Rice Krispies to balance the texture.
• Swap candy eyes for mini chocolate chips or jelly beans for fun variations.
• Make smaller, bite-size treats for little hands by using a mini muffin pan to shape.

How I Like to Serve It

These Frankenstein treats are perfect for a Halloween party platter or as a fun school snack. I love pairing them with some warm apple cider for a cozy fall afternoon. They also make great festive lunchbox surprises that will definitely score brownie points with your little ghouls and goblins!

Notes

• Store treats in an airtight container at room temperature for up to 3 days—no fridge needed or they get chewy.
• If treats firm up too much, microwave them for 10 seconds uncovered to soften before serving.

Closing: These Frankenstein Rice Krispies Treats are a guaranteed crowd-pleaser that always bring a little spooky sweetness and smiles to the kitchen!
