Classic Rice Krispie Treats

Yes; store them in an airtight container at room temperature for up to 5 days. They do not require refrigeration. You can also wrap individual treats in plastic wrap and freeze for up to 1 month.

The marshmallow-to-cereal ratio is off. Use exactly 4 cups Rice Krispies to 4 cups marshmallows; if the mixture seems too thin, you overcooked it or the heat was too high. Stir only until melted, then stop.

Yes; add ½ teaspoon vanilla extract, almond extract, or a few drops of food colouring to the melted marshmallow mixture before adding the cereal. For chocolate versions, use chocolate-flavoured marshmallows or cocoa cereal instead of Rice Krispies.

Use an equal amount (by volume, not weight) of other crispy cereals: Cocoa Krispies, Frosted Flakes, or even popcorn (air-popped or lightly buttered). The treats will have a slightly different texture and flavour.

Yes; the butter helps the marshmallows melt smoothly and adds flavour. If you omit it, the treats become sticky and difficult to cut. Alternatively, use coconut oil or a tiny amount of vegetable oil.

Yes; spray your knife or kitchen scissors with cooking spray or dip them in water and wipe dry between each cut. Warm knives cut more cleanly than cold ones.
