How to Make It

Butter Your Dish

Start by buttering a 9″ x 13″ casserole dish. This step is super important to prevent sticking and makes serving a breeze later!

Melt the Butter

In a large pot over low-medium heat, melt your butter. Let that comforting aroma fill your kitchen—it’s a sign that cozy magic is about to happen.

Add the Marshmallows

Once melted, add the mini marshmallows and stir until smooth. The smell of the marshmallows just starting to melt is heavenly—savor it!

Stir in the Rice Krispie Cereal

Pour in the Rice Krispie cereal and use a spatula to gently fold and stir until every bit of cereal is smothered in that gooey marshmallow goodness. Feel free to get in there with your hands for a more tactile experience!

Press into the Dish

Spoon the mixture into the prepared casserole dish. With a spatula or your hands, press down firmly until it’s nice and flat across the top. This is where the magic sets in! Let it rest for about 30 minutes.

Cut the Treats

Once cooled, carefully remove the treats from the dish and cut them into rectangles of various sizes. The kids will love that each piece is a little different!

Melt the Green Candy Melts

Using a double boiler (or placing a bowl over a pot of boiling water), melt the green candy melts. If the chocolate seems too thick, a teaspoon of vegetable shortening can work wonders to thin it out for a smooth dip!

Dip in Green and Sprinkle

Dip the top of each Rice Krispie treat into the green candy melts, then immediately into the black jimmies. Make sure to coat generously—they need to be flashy!

Add the Eyes

Finish your spooky creation with two royal icing eyes. You can place them wherever you like—don’t forget, these monsters can have personality!

Add Stitches

In a small bowl, melt the black candy melts in the microwave, using 10–15 second increments to avoid burning. Once melted, pour it into a piping bag, and pipe on some fun stitches to give each treat character! Allow to set completely before moving on.

Pro Tips for Success

  • Room Temperature Ingredients: Make sure your butter and marshmallows are at room temperature for the best melting results.
  • Don’t Rush the Setting: Allow the treats plenty of time to cool and firm up so they don’t fall apart when you cut them.
  • Clean-Up Tip: Keep a bowl of warm water nearby for cleaning sticky tools and your hands—it’s a lifesaver!
  • Experiment with Colors: Feel free to use any color of candy melts to match your unique Halloween theme. Who says monsters need to be green?

Flavor Variations

  • Spice it Up: Add a sprinkle of cinnamon or nutmeg when melting the marshmallows for an autumnal twist!
  • Add Extracts: A drop of vanilla or almond extract can elevate the flavor and give depth to your treat.
  • Try Different Sprinkles: Switch it up with themed sprinkles according to your favorite Halloween characters or colors!

Serving Suggestions

These treats are best served fresh, but they’re just as lovely packaged in fun treat bags for party favors. Serve on a spooky platter or alongside a festive punch for an enchanting dessert table!

Make-Ahead & Storage

You can prep these treats a day in advance! Store them in an airtight container at room temperature. They last about 3-4 days, keeping the magic alive for as long as possible!

Leftovers

Got leftovers? Crumble them up and sprinkle over ice cream for a delightful sundae topping. Or, chop them into smaller bits and use them in trail mix—who doesn’t love a little Rice Krispie crunch on the go?

Freezing

Can you freeze them? Yes! Wrap them tightly in plastic wrap, then foil, and store them in a zippered bag. When you’re ready to enjoy, simply let them thaw at room temperature for a few hours.

Reheating

While these treats are best enjoyed fresh, if you want to soften them, place them in the microwave for 5-10 seconds. Just be careful not to overheat!

FAQs

Can I use different cereals?
Absolutely! Feel free to substitute with different cereals like Cocoa Krispies or Fruity Pebbles for a unique twist.

What is the best way to cut them?
Use a sharp knife, wet with warm water, to slice through the treats. This prevents sticking!

Can I color the white candy melts?
Of course! Just make sure to use oil-based food coloring specifically made for candy melts.

What if my candy melts are lumpy?
Don’t worry! Just keep stirring and apply gentle heat. A little vegetable shortening can help regain a smooth consistency.
