Homemade Rice Krispie Treats:
Classic No-Bake Cookie Recipe

Homemade Rice Krispie Treats are the classic no-bake cookie recipe. The treats have become immensely popular not only because they are easy to make, but also because variations of the original recipe abound. And they're inexpensive to make.

This original version is simple to make at home. With just three ingredients – crisp rice cereal, marshmallows, and melted butter or margarine – it is an easy cookie recipe for kids to make. As an added bonus, the bars are a gluten-free cookie!

The original Rice Krispies Treats are said to have been invented in by Kellogg co-workers Mildred Day and Malitta Jensen in 1939, possibly inspired by an earlier recipe that used puffed wheat and molasses. When the Camp Fire Girls organization contacted Kellogg for ideas for fundraiser, the company directed their attention to Day’s easy cookie recipe made from the popular rice cereal.

Homemade Rice Krispie Treats

Prep time: less than 10 minutes

Chilling time: 15-30 minutes

Makes about 20-24 bars


3 tablespoons butter or margarine

1 10-ounce bag large marshmallows (about 40)

6 cups crisp rice cereal (such as Rice Krispies®)

Directions for Homemade Rice Krispie Treats

  1. Line a 13 x 9 baking pan with foil, allowing the ends of the foil to drape over the ends of the pan. Spray the foil lightly with cooking spray.

  2. Set butter and marshmallows in a large, microwave-safe bowl. Microwave on high for 1 minute. Remove the bowl from the oven and stir. Return bowl to the oven. Microwave in 30-second increments, removing the bowl and stirring the marshmallow mixture each time until it is smooth.

  3. While marshmallow mixture is cooking in the microwave, measure rice cereal into a mixing bowl.

  4. When the marshmallow mixture is ready, pour it into the rice cereal. Stir quickly, mixing thoroughly to coat the cereal. With a spatula or wet fingers, press cereal mixture in the prepared baking pan.

  5. Allow cookies to sit for 30 minutes to set. You can place the pan in the refrigerator 15-30 minutes or longer to speed up the process.

  6. Place a cutting board across the top of the baking pan. Flip pan over. Peel back the foil. Use a long bread knife to cut bars into 2-inch squares.

  7. Store bars in an airtight container with waxed paper in between layers.
