Make simple, quick peanut butter bars using rice cereal that require no oven time.

Ingredients

Scale
  • 1/2 cup butter
  • 1 cup creamy peanut butter
  • 1 cup granulated sugar
  • 1 cup packed light brown sugar
  • 1/2 cup milk
  • 1 teaspoon vanilla extract
  • 6 cups crisp rice cereal

Instructions

  1. Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
  2. In a large saucepan, melt the butter over medium heat.
  3. Stir in the granulated sugar, brown sugar, and milk. Bring the mixture to a boil, stirring constantly. Boil for exactly one minute.
  4. Remove the saucepan from the heat. Stir in the peanut butter and vanilla extract until completely smooth.
  5. Pour the hot peanut butter mixture over the crisp rice cereal in a large bowl. Mix gently until the cereal is evenly coated.
  6. Press the mixture evenly into the prepared baking pan using a spatula or wax paper. Do not pack too tightly.
  7. Allow the bars to cool and set completely at room temperature for at least 2 hours, or chill in the refrigerator for 30 minutes for faster setting.
  8. Use the parchment paper overhang to lift the bars from the pan. Cut into squares.

Notes

  • For easy cutting, lightly spray your knife with cooking spray before slicing the cooled bars.
  • Store the bars in an airtight container at room temperature for up to one week.
  • If you prefer a firmer bar, reduce the milk by 1 tablespoon.
