Recipe

Frankenstein Rice Krispie Treats are a delightful Halloween-themed twist on the classic marshmallow and cereal snack. These spooky treats feature green-tinted rice cereal squares decorated to resemble the iconic Frankenstein's monster, complete with a square head, bolts, and a stitched-up expression.
This fun and easy recipe is perfect for Halloween parties, fall gatherings, or simply as a festive treat to enjoy with family and friends. Kids will love helping to create these monstrous snacks, and adults will appreciate the nostalgic flavor with a creative twist.
- 6 cups Rice Krispies cereal
- 4 tablespoons unsalted butter
- 1 (10 oz) package marshmallows
- Green food coloring
- 1/4 cup chocolate chips
- 1/4 cup white chocolate chips
- Black food coloring or black icing
In a large saucepan, melt the butter over low heat. Add marshmallows and stir until completely melted. Remove from heat and add green food coloring until desired shade is achieved. Quickly stir in the Rice Krispies cereal until well coated.
Press the mixture into a greased 9×13 inch pan. Allow to cool completely. Cut into rectangles. Melt chocolate chips and white chocolate chips separately. Use melted chocolate to create hair, eyebrows, and a mouth. Use white chocolate to make eyes and teeth. Add pupils with black food coloring or icing. For bolts, use small candies or cut marshmallows.
For best results, work quickly when mixing the cereal with the marshmallow mixture to prevent it from hardening. If the mixture becomes too stiff, warm it slightly in the microwave.
To achieve a more vibrant green color, use gel food coloring instead of liquid. For a neater presentation, use a pizza cutter to cut the treats into even rectangles. Store in an airtight container at room temperature for up to three days.
Cooking Steps

You'll start by melting butter in a large pan over low heat, then add marshmallows and stir until they're completely melted.
Once your mixture is smooth, add green food coloring to give it that Frankenstein flair, then quickly mix in the Rice Krispies cereal.
Step 1. Melt Butter in Pan

To begin the transformation of ordinary Rice Krispies into monstrous treats, place a large saucepan over low heat. You'll want to use a pan that's big enough to hold all your ingredients comfortably.
Now, it's time to add the butter. You'll need about 3 tablespoons for every 4 cups of marshmallows you plan to use.
Cut the butter into smaller pieces before adding it to the pan. This will help it melt more evenly and quickly. As the butter starts to melt, you'll notice it becoming liquid and clear.
Don't turn up the heat to speed things up, as this could cause the butter to burn. Instead, be patient and let it melt slowly.
While the butter's melting, use a wooden spoon or silicone spatula to gently move it around the pan. This helps distribute the heat and prevents any hot spots.
You'll know the butter's ready when it's completely melted and there's a slight foam on top. At this point, you're all set to move on to the next spooky step in creating your Frankenstein Rice Krispie Treats!
Step 2. Add Marshmallows, Stir Until Melted

The next crucial step in creating your monstrous treats involves adding the marshmallows. Once your butter has melted completely, it's time to introduce the star ingredient. Pour in the marshmallows, making sure to add them gradually while stirring.
You'll want to use about 10 ounces of marshmallows for every 6 cups of Rice Krispies cereal. As you stir, you'll notice the marshmallows starting to soften and melt. Keep stirring consistently to prevent any burning or sticking to the bottom of the pan.
The mixture will slowly transform into a gooey, sticky mass that's perfect for binding your cereal together. Don't rush this process; it usually takes about 3-5 minutes for the marshmallows to melt completely.
If you're feeling adventurous, you can add a few drops of green food coloring at this stage to give your treats a spooky Frankenstein hue. Just remember, a little goes a long way!
Once your marshmallow mixture is smooth and free of lumps, you're ready to move on to the next step in creating your deliciously monstrous Rice Krispie treats.
Step 3. Add Green Food Coloring

Now that your marshmallow mixture is smooth and creamy, it's time to add the green food coloring for that perfect Frankenstein look.
Grab your bottle of green food coloring and carefully add a few drops to the melted marshmallow mixture. Start with just 3-4 drops, as you can always add more if needed. Remember, it's easier to add color than to take it away!
Using your spatula or wooden spoon, gently fold the food coloring into the marshmallow mixture. You'll see the white marshmallow slowly transform into a spooky green color.
Keep stirring until the color is evenly distributed throughout the mixture. If you want a darker, more monster-like green, add a drop or two more of food coloring and mix again.
Be careful not to overmix, as this can make your treats tough. Once you've achieved the desired shade of green, you're ready for the next step.
The green color will make your Frankenstein Rice Krispie Treats look extra creepy and perfect for Halloween parties or monster-themed events.
Get ready to impress your friends with these ghoulishly green treats!
Step 4. Add Rice Krispies Cereal

With your green marshmallow mixture ready, it's time to incorporate the star ingredient: Rice Krispies cereal. Grab your large mixing bowl and measure out 6 cups of Rice Krispies.
You'll want to work quickly, as the marshmallow mixture can start to set if left too long.
Pour the green marshmallow mixture over the Rice Krispies, making sure to scrape every last bit from the pot. Using a spatula or wooden spoon, gently fold the cereal into the marshmallow mixture.
It's important to be thorough but careful, as you don't want to crush the cereal. Keep folding until all the Rice Krispies are evenly coated with the green mixture.
As you mix, you'll notice the treats starting to come together. They should be sticky and hold their shape when pressed.
If the mixture seems too dry, you can add a bit more melted marshmallow. If it's too wet, toss in a handful more cereal.
Step 5. Press Into Greased Pan

Once you've thoroughly mixed your green Rice Krispie treat mixture, it's time to shape it. Grab a 9×13-inch baking pan and lightly grease it with butter or cooking spray. This will prevent your treats from sticking and make them easier to remove later.
Carefully transfer the warm, gooey mixture into the greased pan. Using a spatula or your hands (slightly dampened to prevent sticking), spread the mixture evenly across the pan. Press down firmly to create a compact, uniform layer. Make sure you're pushing the mixture into the corners and edges for a neat appearance.
As you press, aim for a consistent thickness throughout. This will ensure that your Frankenstein treats cook evenly and look their monstrous best.
Don't worry if it's not perfect – Frankenstein wasn't exactly a looker either! Once you're satisfied with the shape, let the treats cool at room temperature. This allows them to set properly, making them easier to cut and serve later.
In about an hour, your ghoulishly good Frankenstein Rice Krispie treats will be ready for the next spooky step!
