Make classic Rice Krispie Treats better by using nutty, browned butter for a deeper flavor.

Ingredients

Scale
  • 6 tablespoons unsalted butter
  • 1 package (10 ounces) miniature marshmallows
  • 1 teaspoon vanilla extract
  • 6 cups crispy rice cereal
  • Pinch of salt

Instructions

  1. Line an 8×8 inch baking pan with parchment paper, leaving an overhang on two sides for easy removal. Lightly grease the paper.
  2. Place the butter in a medium saucepan over medium heat. Cook the butter, swirling the pan occasionally, until it melts, foams, and then brown bits form at the bottom and it smells nutty. This takes about 5 to 7 minutes. Watch carefully to prevent burning.
  3. Remove the saucepan from the heat immediately once the butter is browned.
  4. Add the marshmallows and salt to the hot brown butter. Stir constantly until the marshmallows are completely melted and smooth.
  5. Remove the pan from the heat. Stir in the vanilla extract.
  6. Add the crispy rice cereal to the marshmallow mixture. Fold gently until the cereal is evenly coated.
  7. Transfer the mixture to the prepared baking pan. Lightly press the mixture into an even layer using a piece of wax paper or lightly greased spatula. Do not press too firmly, as this makes the bars hard.
  8. Let the bars cool completely at room temperature for at least 1 hour before lifting them out using the parchment overhang.
  9. Cut into 16 squares.

Notes

  • For chewier bars, use fresh marshmallows. Older marshmallows result in harder treats.
  • If you press the mixture too hard into the pan, the bars will set too densely and lose their chewiness. Press just enough to level the surface.
  • Store the finished bars in an airtight container at room temperature for up to 3 days.
