How To Make A Rice Krispie Treat

  1. Melting Marshmallows and Butter: In a microwave, heat the marshmallows and butter together for 30 seconds. This softens them for easy mixing.
  2. Mixing with Cereal: Once melted, stir in the rice cereal until it’s fully coated with the marshmallow mixture.
  3. Setting in Dish: Transfer this mixture into a buttered baking dish, spreading it evenly.

For an extra zesty flavor, try spreading a layer of lemon curd on top – it’s a deliciously tangy addition!

Expert Tips

  • Remove Marshmallows Quickly: As soon as the marshmallows are melted, take them out of the microwave. Overcooking can make them hard and thick, affecting the treat’s texture.
  • Stir Gently: When mixing the cereal with the marshmallows, stir gently to avoid breaking the crispy rice cereal, which can change the treat’s texture.
  • Press Lightly: Press the mixture into your pan softly. You want a gooey, light treat, not one that’s too firm and compact.

Frequently Asked Questions
