Ingredients
 

  • 1/4 cup salted butter
  • 1/3 cup milk
  • 1 cup sugar
  • 1 1/3 cups old-fashioned or quick cooking oats
  • 1/2 cup creamy peanut butter
  • 1 tsp vanilla extract

Instructions

  • In a medium saucepan over medium heat, melt the butter.
  • Once the butter is melted, add the milk, and granulated sugar to the saucepan. Stir until the mixture is smooth.
  • Increase the heat to medium-high and bring the mixture to a rolling boil. Let it boil for EXACTLY 1 minute, stirring constantly to prevent burning.
  • Remove the saucepan from the heat. Immediately stir in oats, creamy peanut butter, and vanilla extract until well combined and starting to thicken, about 30 seconds to 1 minute. Allow the mixture to rest 3 minutes.
  • Using a spoon or cookie scoop, drop spoonfuls of the cookie mixture onto parchment paper. Leave a little space between each cookie as they will spread slightly as they cool.
  • Allow the cookies to cool and set at room temperature for at least 30 minutes, or until firm to the touch.

Notes

Storage:
Store any leftover no-bake cookies in an airtight container for up to 3 days. If you keep them in the fridge, they will store for up to 5 days and retain their texture better.
These Peanut Butter No Bake Cookies also freeze like a dream. Freeze for up to 2 months, then thaw on the counter overnight.
Tips: 
  • Always stir constantly when the mixture is boiling. This is to prevent it from burning, but will allow the sugar to dissolve.
  • Add the vanilla at the end. If you add it too soon, then it will evaporate in the cookie dough mixture.
  • Use a cookie scoop to drop equal-sized cookies onto the baking sheet. They will spread a little bit as they cool, so leave about 1-inch of space in between.
  • Make sure the cookies cool for long enough before enjoying. The texture needs to set or else they will fall apart.
