Ingredients

Scale

Wet Ingredients

  • 1/2 cup butter
  • 1/2 cup milk
  • 1 cup smooth peanut butter
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1 1/2 cups brown sugar
  • 3 cups old fashioned oats
  • Pinch of salt

Instructions

  1. Prepare Work Surface: Cover a baking sheet with wax paper and set aside to prevent the cookies from sticking after shaping.
  2. Cook Sugar Mixture: In a large saucepan over medium heat, combine the brown sugar, butter, and milk. Stir frequently and bring the mixture to a rolling boil. Maintain the boil and continue stirring for one full minute to ensure the sugar dissolves fully and the mixture thickens slightly.
  3. Add Peanut Butter and Flavorings: Turn off the heat. Stir the smooth peanut butter into the hot sugar mixture until completely smooth. Then add the vanilla extract and mix well to incorporate all flavors.
  4. Combine with Oats: Add the old fashioned oats and a pinch of salt to the peanut butter mixture. Stir thoroughly until all oats are evenly coated and the mixture is uniform.
  5. Shape Cookies: Using a spoon or cookie scoop, drop 2-tablespoon portions of the mixture onto the prepared wax paper, spacing them apart to allow for minimal spreading.
  6. Chill Cookies: Place the baking sheet in the refrigerator for at least one hour or until the cookies are firm and set. Once chilled, enjoy them cold or allow them to reach room temperature before serving.

Notes

  • Use natural, smooth peanut butter for the creamiest texture.
  • Ensure to maintain the rolling boil for the full minute to properly set the cookies.
  • Store cookies in an airtight container in the refrigerator for up to a week.
  • For a nuttier texture, you can use old-fashioned rolled oats or quick oats as per preference.
  • If you prefer a sweeter cookie, adjust brown sugar slightly, but keep cooking times consistent.
