Ingredients
- Holiday Rice Krispies: These seasonal boxes appear in stores in November and include red and green cereal pieces for a festive look. If you spot one, grab it—these can sell out quickly.
- Mini marshmallows: Mini marshmallows melt more easily and give a smoother marshmallow mixture.
- Butter: Salted butter works well; use unsalted if you prefer but add a pinch of salt to the marshmallow mixture.
- Vanilla extract: A small amount enhances the flavor without overpowering the treats.
Note: The instructions below show the stovetop method first. A microwave method is also included for convenience.
How to Make Christmas Rice Krispies Treats
Start by lining an 8×8 or 9×9 baking dish with overlapping pieces of parchment paper, folding the edges over to create “handles.” Lightly grease the dish so the parchment stays in place.
Add the butter to a large saucepan or high-sided skillet and melt over medium heat. Once melted, add the mini marshmallows and stir so they are coated with butter.
Continue stirring over gentle heat until the marshmallows are fully melted and smooth. Remove from the heat and stir in the vanilla extract.
Adding the Rice Krispies
Fold the cereal into the melted marshmallow mixture with a silicone spatula until every piece is coated. Work quickly—marshmallows can set as they cool, which makes the mixture harder to spread.
Immediately transfer the sticky mixture into the prepared pan and smooth it into an even layer. Be gentle when smoothing; pressing too hard compresses the cereal and results in a dense bar. A light touch keeps the treats chewy and soft.
Cooling the Treats
Cover the pan with a towel or plastic wrap and let the treats set at room temperature for at least 1 hour. Refrigeration speeds things only slightly and tends to make the bars firmer and denser, so room-temperature setting is preferred if you like a soft, gooey texture.
Cutting the Treats
After they have set, lift the parchment from the pan and use a sharp knife to cut the treats. For an 8×8 pan, cut into thirds horizontally and vertically to yield about nine treats. For a doubled batch in a 9×13 pan, cut into 18 pieces by slicing thirds across the short side and dividing lengthwise as described.
Storing Leftover Rice Krispies Treats
Place cooled, sliced treats in an airtight container. Store at room temperature for up to 3 days for the best texture. If stored in the refrigerator they will keep for up to 5 days but will be firmer. For longer storage, wrap each treat in plastic wrap, place in a freezer-safe bag, and freeze for up to 2 months. Thaw at room temperature before serving.
Microwave Method
- Melt the butter and marshmallows in a microwave-safe bowl in 30-second intervals, stirring between intervals until smooth.
- Stir in the vanilla extract once the marshmallows are fully melted.
- Fold in the cereal until fully coated.
- Transfer to a parchment-lined baking dish and smooth gently into an even layer.
- Allow to cool at room temperature for at least 1 hour before slicing and serving.
Holiday Variations
You can use seasonal cereals or tint the marshmallow mixture with food coloring. Top bars with holiday candies or chocolate for an extra festive finish. A few ideas:
- Valentine’s Day – Pink or red treats with conversation hearts.
- Spring – Pastel colors in blue or green.
- St. Patrick’s Day – Green treats with themed marshmallows or cereals.
- Easter – Soft pastel colors and seasonal candies.
- 4th of July – Red and blue with star-shaped candies.
- Halloween – Orange or yellow with candy corn.
- Thanksgiving – Warm autumn colors with fall-shaped candies.
- Christmas – Holiday Rice Krispies and seasonal candies as desired.
Frequently Asked Questions
Yes. They can be made up to 3 days ahead and stored at room temperature, though they’re best the day after making. Alternatively, freeze individual bars and thaw at room temperature when ready to serve.
Store treats at room temperature in an airtight container to keep them soft. Avoid pressing the cereal mixture firmly into the pan, and avoid refrigeration unless you prefer a firmer texture.
Yes. Press the mixture gently into greased molds, cover, and allow to set at room temperature for 1–2 hours before unmolding. Lightly greasing the molds helps with release.
Doubling the Recipe
To make a larger batch for a 9×13 pan, double all ingredients. Use a slightly deeper pan if possible and allow 1½ to 2 hours for cooling instead of the standard hour for smaller pans, as larger pans need more time to set.
