Introduction

Mint Chocolate Rice Krispie Treats bring a festive twist to a classic favorite. These chewy, chocolaty bars are topped with a creamy mint frosting, making them perfect for holidays or any time you crave a refreshing dessert.

The image shows a rectangular dessert cut into 20 even squares, arranged in 4 rows and 5 columns on a wooden board. The dessert has two visible layers: a dark brown, textured bottom layer that looks like a chocolate or rice crispy base, and a thick, smooth, pale green layer of frosting spread evenly on top with slight swirls. Around the dessert, there are scattered chocolate chips, a white bowl filled with puffed cereal, and some white marshmallows on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

1/2 cup butter
10 ounces mini marshmallows

3 tablespoons unsweetened cocoa powder
1 cup semi-sweet chocolate chips

6 1/2 cups rice krispies cereal
3/4 cup butter (room temperature)

3 cups powdered sugar
1 1/2 tablespoons water
1/2 teaspoon peppermint extract

6 drops green food coloring

Instructions

Step 1: Line a 9-inch by 13-inch baking dish with parchment paper, leaving some foil hanging over the edges. Spray the foil with non-stick cooking spray and set aside.
Step 2: In a large pot over medium heat, melt 1/2 cup butter. Add the mini marshmallows and cocoa powder, stirring frequently until the marshmallows are completely melted and smooth.

Step 3: Remove the pot from heat and stir in the chocolate chips until fully melted and combined.
Step 4: Pour in the rice krispies cereal and stir until all the cereal is evenly coated with the chocolate marshmallow mixture.
Step 5: Transfer the mixture to the foil-lined baking dish and press it into an even layer using your hands or a rubber spatula. Be careful if using your hands, as the mixture will be hot.

Step 6: Allow the treats to cool completely, about 30 minutes to 1 hour.
Step 7: For the mint frosting, add 3/4 cup room-temperature butter to a stand mixer or large bowl. Beat on low speed while gradually adding the powdered sugar, one cup at a time, mixing well between additions.
Step 8: Once the frosting starts to pull away from the sides of the bowl, increase the speed to high and beat until light and fluffy.

Step 9: Mix in the water, peppermint extract, and green food coloring until the frosting is evenly colored. Adjust food coloring as needed to reach your desired shade.
Step 10: Spread the mint frosting evenly over the cooled rice krispie treats.
Step 11: Use the foil edges to lift the treats from the dish and cut into squares. A 4 by 5 grid will yield 20 pieces.

Tips & Variations

To make the treats extra festive, sprinkle crushed peppermint candies on top of the frosting before it sets.
Use white chocolate chips instead of semi-sweet for a sweeter, milder chocolate flavor.
If you prefer a stronger mint flavor, add an extra 1/4 teaspoon of peppermint extract to the frosting.

Storage

Store the treats in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week. Bring to room temperature before serving for the best texture. These treats do not freeze well due to the frosting.

FAQs

Can I use regular-sized marshmallows instead of mini marshmallows?

Yes, you can use regular marshmallows. Just be aware they may take slightly longer to melt and incorporate evenly.

What can I substitute if I don’t have peppermint extract?

If you don’t have peppermint extract, you can use vanilla extract for a different but still delicious flavor, or try a few drops of mint-flavored syrup if available.
