The Story Behind My Frankenstein Halloween Rice Krispie Treats
A Family Halloween Tradition with a Twist
A few years ago, my twins were invited to a classroom Halloween party, and we had exactly one night to whip up something festive. Exhausted, I almost reached for store-bought treats—but then I remembered how quick rice krispie bars are. That night, we made them spooky: green faces, candy eyes, chocolate stitches. Frankenstein Halloween Rice Krispie Treats were born in our kitchen, complete with googly eyes and giggles.
That little late-night kitchen session became an annual thing. The kids love dipping them and making each face different. Now every October, it’s our go-to treat. These Frankenstein Halloween Rice Krispie Treats have become a neighborhood hit—easy, creepy-cute, and great for class parties or bake sales.
Why These Treats Work for Every Halloween Gathering
These Frankenstein treats check every Halloween box: they’re no-bake, microwave-friendly, and require just a few pantry basics. They’re festive without being too fussy. Whether you’re prepping for a haunted house party or just want something fun after school, these bars offer a balance of fun and flavor. The bright green candy melts create that classic Frankenstein look, while the black jimmies and chocolate “stitches” add just the right amount of spooky detail.
And let’s not forget—they hold up well in lunchboxes and containers. They’re the kind of treat that looks amazing without needing bakery skills, making you feel like a Halloween rockstar with minimal effort.
Frankenstein Halloween Rice Krispie Treats
Ingredients
- 6 cups rice krispie cereal
- One 10oz bag mini marshmallows
- 4 tbsp unsalted butter
- 10 oz green candy melts
- 3 oz black candy melts
- Royal icing eyes
- Black jimmies sprinkles
Instructions
- Butter a 9″ x 13″ casserole dish.
- In a large pot over low-medium heat, melt the butter.
- Add the marshmallows and stir until smooth.
- Pour in the rice krispie cereal and, with a spatula, stir until the cereal is evenly coated with marshmallows.
- Spoon the mixture into the prepared casserole dish and press until the rice krispies fill the dish and the top is flat.
- Allow to set for 30 minutes.
- Remove the cooled rice krispie treats from the dish and cut into rectangles of various sizes.
- Place a bowl over a small pot of boiling water and add the green candy melts to it.
- Stir until melted. If the chocolate is too thick for dipping, adding a teaspoon of vegetable shortening.
- Dip the top of each rice krispie treat into the green candy melts and then into the black jimmies sprinkles.
- Add two royal icing eyes.
- In a small bowl, melt the black candy melts in the microwave using 10 – 15 second increments.
- Pour into a piping bag and pipe stitches onto the treats.
- Allow to set completely before packaging.
Notes
Keep your kitchen equipment/utensils free of water when melting the chocolate. Getting water in the melting/melted chocolate will cause it to seize.
Using chocolate in place of candy melts: If you’d prefer to use chocolate in place of the candy melts, you can use white chocolate with green gel food coloring and dark chocolate with black gel food coloring to replace the green and black candy melts.
Don’t have a double boiler? You can melt your chocolate in the microwave using 10 second increments. Just be careful, it’s very easy to over-cook chocolate this way.
If the chocolate is too thick: You can thin it by adding a little bit of vegetable shortening. Stir a little bit in, stirring until it’s completely melted and test to see if it’s the consistency you want. A little bit goes a long way.
Storage: Rice krispie treats can be stored in an air tight container at room temperature and are best when eaten within three days. Nutrition

How to Make Frankenstein Halloween Rice Krispie Treats Step-by-Step
Gathering Your Ingredients & Tools
To make Frankenstein Halloween Rice Krispie Treats, you don’t need a huge list of ingredients or fancy kitchen tools. Here’s exactly what you’ll need:
Ingredients:
- 6 cups Rice Krispie cereal
- One 10 oz bag mini marshmallows
- 4 tbsp unsalted butter
- 10 oz green candy melts
- 3 oz black candy melts
- Royal icing eyes
- Black jimmies sprinkles
Tools:
- 9″x13″ casserole dish
- Spatula or wooden spoon
- Double boiler or microwave-safe bowls
- Piping bag (for stitches)
You can substitute green and black candy melts with white chocolate dyed with gel food coloring (green and black), especially if that’s what you already have on hand. Just be cautious with water near melting chocolate—it’ll seize fast.
Cooking & Decorating: Tips for Success
Start by buttering a 9×13 casserole dish to avoid sticking. Then melt your butter in a large pot over low-medium heat. Stir in marshmallows until smooth. Once melted, remove from heat and immediately fold in the Rice Krispies. Mix well and press into your prepared dish. Let it cool for 30 minutes.
Once firm, cut into rectangles—these are your Franken-heads.
To create Frankenstein’s signature look:
- Melt green candy melts using a double boiler or microwave (short bursts: 10–15 seconds).
- Dip the tops of your bars into the green coating, then quickly press into black jimmies for hair.
- Add two icing eyes to each bar while the candy melt is still tacky.
- Melt the black candy melts, transfer to a piping bag, and draw on stitches.
Let everything set before serving or packaging. If your candy melt feels too thick, add a teaspoon of vegetable shortening to loosen it up.
These bars hold shape well, and the decorations stay intact for a couple of days, making them perfect for make-ahead parties.
Fun Variations & Creative Twists on Frankenstein Halloween Rice Krispie Treats
Customize the Look for Every Little Monster
One of my favorite things about Frankenstein Halloween Rice Krispie Treats is how easy it is to personalize them. While the classic version has green candy melts and spooky stitches, you can let your creativity run wild with these fun alternatives:
- Color swap: Try purple, orange, or even blue candy melts to create a whole cast of Halloween creatures—think monsters, zombies, or vampires.
- Different expressions: Use extra black candy melt to pipe quirky smiles, fangs, or even angry brows.
- Mini Frankensteins: Cut the bars smaller for bite-sized versions, perfect for party platters or trick-or-treat bags.
If you’re making these with kids, turn it into a decorating station. Set out bowls of candy eyes, melted chocolate, and sprinkles—and let them each design their own “monster bar.”
Allergy-Friendly and Storage Tips
Need to make your treats safe for everyone? Here are a few simple swaps:
| Allergen | Swap Suggestion |
|---|---|
| Dairy (butter) | Use a vegan butter or coconut oil |
| Marshmallows | Look for gelatin-free or vegan marshmallows |
| Candy melts | Use allergy-friendly chocolate + food coloring |
For storage, keep your Frankenstein treats in an airtight container at room temperature. They stay soft and tasty for up to three days—though they usually vanish much faster at our house.
Avoid storing them in the fridge unless your home is very warm, as condensation can cause the candy melts to sweat and the sprinkles to bleed.
And if you’re prepping ahead, undecorated Rice Krispie bars freeze well. Just thaw, decorate, and enjoy!
