Ingredients

  • 1/2 cup milk
  • 1/2 cup butter (1 stick)
  • 1 cup granulated sugar
  • 1 cup brown sugar light or dark
  • 3/4 cup creamy peanut butter
  • 1 teaspoon vanilla extract
  • 3/4 teaspoon fine sea salt
  • 3 cups old-fashioned rolled oats

Instructions

  • Lay a large sheet of parchment paper or wax paper on the counter. This is where the cookies will cool and set.
  • In a medium saucepan over medium-high heat, combine the milk, butter, granulated sugar, and brown sugar. Stir occasionally until the butter is melted and everything is well combined.
  • Once the mixture comes to a full rolling boil, stop stirring. Continue boiling until the mixture reaches 234–240°F on a candy thermometer (soft-ball stage), about 1-2 minutes of steady boiling. This step ensures the cookies will set properly.
  • Remove from heat. Stir in the peanut butter, vanilla, and salt until smooth.
  • Add the rolled oats and stir until evenly coated and thickened.
  • Drop heaping tablespoons of the mixture onto the prepared paper. Allow to cool and set at room temperature for 20–30 minutes, until firm. Enjoy!
