Rice Krispie Treats Recipe

You only need three ingredients to make perfect Rice Krispie treats: cereal, marshmallows, and butter.
Prep Time 5 minutes
Cook Time 10 minutes
Total Time 15 minutes
Servings 9 bars

Ingredients

  • 6 tablespoons butter, salted or unsalted (3 ounces; 85 grams)
  • 1 (10 ounce) bag mini or regular marshmallows
  • 5 cups Rice Krispies cereal (about 8 ounces; 226 grams)

Instructions

  1. Prepare your pan. For thick bars: Grease an 8x8x2-inch pan with nonstick cooking spray or softened butter. For thin bars: grease a 9x13 inch pan with nonstick cooking spray or butter.

    For the easiest removal, line the pan with two pieces of crisscrossed parchment paper.

  2. Melt the butter. In a large pot, melt 6 tablespoons of butter over low heat.

  3. Add the marshmallows. Add one 10-ounce bags of marshmallows. Stir until marshmallows are melted.

  4. Add the cereal. Remove the pot from the heat and stir in 5 cups of crispy rice cereal until coated.

  5. Press into pan. Gently press the mixture into the prepared pan.

  6. Cut into squares. Allow the bars to set for an hour or so and then cut into bars.

  7. Store at room temperature. Cover the leftovers and store at room temperature.

Recipe Notes

Butter. For the best flavor, use salted butter. Unsalted butter, margarine, and coconut oil can also be used.

Marshmallows: Mini-marshmallows melt the easiest. Regular marshmallows also work. 

Store: Cover the bars and store on the counter. Rice Krispie treats may be refrigerated or frozen. Place a piece of waxed paper between the bars before chilling. For the best texture allow the bars to come to room temperature before serving.
