Ingredients
For this fun-filled treat, you’ll need:
- 6 cups Rice Krispie cereal: The backbone of our treats, providing that iconic crunch and texture.
- One 10 oz bag of mini marshmallows: Sweet, gooey, and sticky—the heart of this dessert!
- 4 tbsp unsalted butter: To meld everything fabulously and add a touch of richness.
- 10 oz green candy melts: To create that signature Frankenstein hue. Honestly, how can you resist that vibrant green!
- 3 oz black candy melts: For the spooky dimension and the stitches that give our little monster character.

- Black jimmies sprinkles: To add texture and a bit more fun!
Now for the tips: opt for high-quality ingredients when you can. It makes a difference in taste. I rap my hands on the counter when I realize I’ve used stale marshmallows before—oops! Don’t forget to grease that casserole dish well; nothing’s worse than risking a rice treats massacre during removal.
How to Make It Step-by-Step
Okay, so let’s dive into the joyful (and somewhat chaotic) process of creating our Frankenstein Halloween Rice Krispie Treats. Let’s be real—it’s a path of goo and grins.
-
Butter Up Your Dish: First things first, grab that 9" x 13" casserole dish and butter it generously. I like to think of this step as preparing a cozy bed for our treats.
-
Melt the Butter: Over low-medium heat, toss in your 4 tablespoons of unsalted butter in a large pot. As it begins to melt, the kitchen starts smelling cozy—like a warm hug on a brisk autumn day.
-
Add Marshmallows: Once your butter melts, pour in the 10 oz bag of mini marshmallows. Stir continuously until you achieve a smooth consistency. Honestly, this step is pure magic. The melting marshmallows transform into creamy goo, and it’s a sight to behold.
-
Combine with Rice Krispies: Now comes the fun part: gently fold in 6 cups of Rice Krispie cereal. Use a spatula to mix everything together. Don’t fret if you see a few marshmallows that refuse to blend in; it just adds character! Press the mixture firmly into the prepared casserole dish, smoothing the top.
-
Let it Set: Allow your mixture to cool and set for about 30 minutes. This is the time when I try to stay out of the kitchen. It’s so hard to resist making "taste tests” as you wait!
-
Cut and Prepare to Dip: Once cooled, remove the entire Rice Krispie treat from the dish. I often make this process a bit of a spectacle, requiring a family effort to delicately lift the gooey slab out—there’s danger of it breaking apart, so watch out! Cut into rectangles of varying sizes, and be prepared for a happy dance as you survey your creations.
-
Melt the Green Candy: In a heat-safe bowl set over a pot of simmering water (a double boiler works wonders here), melt the green candy melts. Stir until it’s silky smooth—if your mixture is too thick, adding a teaspoon of vegetable shortening can save the day.
-
Dip Those Treats: Once your candy melts are ready, dip the top of each treat into the colorful green goodness. Roll gently in black jimmies sprinkles, and let them be overtaken by the spookiness!
-
Add Eyes and Stitches: Top each treat with two royal icing eyes—because no monster is complete without a personality! For the finishing touch, melt the black candy melts in the microwave (10–15 second increments, please!). Use a piping bag to carefully add stitches on each treat. Your Frankenstein is practically complete—screams of delight are imminent!
-
Setting the Stitches: Allow everything to set completely before packaging. You wouldn’t want your Frankenstein running away now, would you?
Taking pride in a treat like this brings unhealthy doses of joy. You’ll find the sounds of laughter, along with taste-testing, fill the kitchen as the kids admire their (seemingly) goblin-like creations!
Tips for Best Results
- Get Creative: Don’t be shy! Experimenting with visible toppings—think gummy worms or crushed-up Halloween candies—adds a personal touch.
- Cooling Time Matters: Allow sufficient cooling time before cutting. It minimizes any crumbles and keeps the treats intact.
- Pop it in the Fridge: If you’re in a hurry, placing your assembled Rice Krispie treats in the fridge for a short while helps them firm up faster.
Ingredient Substitutions & Variations
Feel free to get experimental with these treats! Here are a few swaps or variations to consider:
- Nut Butters: For a nutty twist, use peanut butter or almond butter in place of some of the butter when melting your marshmallows.
- Flavored Extracts: Add a splash of vanilla or almond extract to give your marshmallow mix a flavor depth.
- Festive Colors: You can always switch up the colors based on any holiday—you might find love for red for Christmas or orange for fall!
Serving Suggestions
Pair your Frankenstein Halloween Rice Krispie Treats with a big glass of milk, a steaming cup of apple cider, or perhaps some spooky-themed juice. Picture this: you, a plate of treats, and your favorite rom-com, all while basking in the delight of being spellbound by the moment. It’s bliss, I dare say!
How to Store and Reheat Leftovers
Here’s the practical advice I needed when I was a beginner: store leftover treats in an airtight container (preferably separated by parchment paper) at room temperature. They’ll last for about a week if you can resist the temptation. To reheat, try using the microwave in short bursts to regain a bit of gooeyness, but don’t go overboard, or you’ll be left with more marshmallow soup than treat!
Make-Ahead and Freezer Tips
You can also make these ahead of time. The treats freeze surprisingly well! Just wrap them securely, and they can last up to three months. When you’re ready to enjoy, let them thaw at room temperature for a little while, or pop them in the microwave for a quick warm-up.
Common Mistakes to Avoid
- Skipping the Butter: It’s a common rookie mistake. Not greasing the pan or the spatula leads to a sticky disaster!
- Overheating Chocolate: Avoid melting the chocolate too quickly; it’ll seize up on you!
- Not Letting Them Set: I’ve fallen victim to the urge to cut them too soon. Trust me; patience pays off!
Frequently Asked Questions (FAQ)
Can I use regular marshmallows instead of mini ones?
Yes, although mini ones melt more evenly, regular marshmallows work just fine!
How can I make them gluten-free?
Check that your Rice Krispies are gluten-free, and you’re all set!

Absolutely! Experiment with different sprinkles, crushed candies, or even edible glitter for a festive touch!

For sure! You can use cookie cutters to shape them after they’ve set, if you want to get fancy.

Stick to the recipe’s measurements, and store them well to keep them fresh; moisture is your pal here!
