Rice Krispie Treats

This classic Rice Krispie Treats recipe brings back the warm, gooey, nostalgic dessert you remember from childhood. Soft, chewy marshmallow pulls meet light, crispy rice cereal for a texture contrast that is both airy and satisfying. The aroma of melted butter and vanilla fills the kitchen as you stir, creating a homey scent that invites hungry hands. These bars are best when served within a day or two for peak chewiness, but they also travel well to potlucks, school lunches, or movie nights. If you love variations, you can find related ideas in our Rice Krispie Treats guide to inspire seasonal twists and presentation tips.

Ingredients

3/4 cup unsalted butter (1 1/2 sticks)
Use unsalted butter so you can control the salt level in the recipe. It melts quickly and helps the marshmallows become silky.
Two 10-ounce bags mini marshmallows (total of 20 ounces)
Mini marshmallows melt evenly and give the bars their classic chew and glossy finish.
1/2 teaspoon pure vanilla extract
Adds a warm, fragrant depth that lifts the sweetness of the marshmallows.
Pinch of salt
Balances sweetness and enhances the flavors of butter and vanilla.
9 cups crispy rice cereal
Provides the light, crispy structure. Measure loosely to keep the texture perfect and avoid packing.

Step-by-step Instructions

Line a 9×13-inch baking pan with parchment paper and lightly grease it.
Tip: Let the parchment hang over the edges to lift the set bars out easily.
In a large pot, melt the unsalted butter over medium heat.
Watch carefully so the butter does not brown.
Once the butter is melted, add the mini marshmallows to the pot and stir until completely melted and combined.
Stir constantly for a smooth, lump-free mixture.
Remove the pot from heat and stir in the vanilla extract and a pinch of salt.
Stir briefly so the vanilla is evenly distributed.
Fold in the crispy rice cereal, mixing until all the cereal is evenly coated with the marshmallow mixture.
Work quickly while the mixture is warm so the marshmallow coats evenly. For a firmer bar, add the cereal a bit at a time.
Transfer the mixture to the prepared baking pan and gently spread it out, pressing down lightly without packing it too tightly.
Use a lightly greased spatula or another sheet of parchment to press down smoothly.
Allow the treats to set at room temperature for at least 1 hour.
Do not refrigerate, as that can make them overly firm.
Once set, lift the treats out of the pan using the parchment paper, cut into squares, and store in an airtight container.
Tip: For clean cuts, use a sharp knife warmed in hot water and wiped dry between slices.
