How to Make Grinch Rice Krispie Treats?
Step 1: Melt the Butter 🧈
Start by melting three tablespoons of unsalted butter over low-medium heat in a large saucepan. Stir occasionally, making sure it doesn’t brown. You want it perfectly melted for smooth mixing.
Step 2: Add Marshmallows 🥣
Once the butter is melted, pour in a pack of mini marshmallows. Stir the mixture constantly until the marshmallows are almost completely melted. Then, add a few drops of green food coloring and mix quickly. Adjust the color until you get that signature Grinch green. Remove the pan from heat when everything is smooth and vibrant.
Step 3: Mix in the Rice Krispies 🌟
Add six cups of Rice Krispies cereal to the green marshmallow mixture. Stir gently but thoroughly, ensuring every piece of cereal is coated in the gooey goodness. Be quick here, as the mixture begins to firm up as it cools.
Step 4: Spread and Shape 🎄
Lightly coat your 13×9-inch baking pan with cooking spray. Pour the cereal mixture into the pan and gently press it down with a spatula to create an even surface. Don’t press too hard; you want the treats to remain fluffy and light.
Step 5: Add the Grinchy Touch ❤️
While the mixture is still sticky, gently press jumbo red heart quins onto the surface. Space them out so every square gets its own adorable heart. Allow the treats to cool and set for about 10-15 minutes before cutting them into squares. Enjoy the festive bites!

Tips for Making the Recipe
- Work Quickly: Once the marshmallows are melted, you’ll want to move fast to mix and press the treats before they set.
- Use Fresh Marshmallows: Fresh marshmallows melt better and lead to softer, chewier treats. Skip the stale ones hanging out in your pantry!
- Double the Batch: These disappear quickly, so you might want to double the recipe from the start.
- Non-Stick Tip: Lightly spray your spatula with cooking spray to avoid sticking when pressing the mixture into the pan.
- Cool Completely: Make sure the treats have set before cutting to get clean, neat squares.
How to Serve Grinch Rice Krispie Treats?
These treats deserve a little extra holiday magic! Arrange them on a festive platter, and sprinkle the tray with red and green sprinkles for added decorations. You can also wrap individual squares in clear plastic wrap tied with holiday ribbons for party favors or gifts. For ultimate nostalgia, serve them alongside a warm mug of hot cocoa topped with whipped cream. Bonus points if you’re watching The Grinch!
Make Ahead and Storage
Got leftovers? (Highly unlikely, but just in case!) Here’s how to store them:
- Room Temperature: Store the treats in an airtight container at room temperature for up to four days. Make sure they’re tightly sealed to keep them soft and chewy.
- Refrigeration: If you want them to last a little longer, pop the container in the fridge for up to a week. Be aware that refrigeration may make them firmer.
- Freezing: Need treats for next week’s party? You can freeze the cut pieces! Wrap each square individually in plastic wrap, then store them in a freezer-safe bag. To serve, just bring them back to room temperature for about 30-60 minutes, and they’ll taste as good as new.
With these Grinch Rice Krispie Treats, you’ll have a simple and festive dessert that will make your holiday season even sweeter. I hope this recipe brings as much joy to your kitchen as it did to mine! ❤️🎅
