  • Line two large cookie sheets with parchment paper or wax paper.  Measure out all the ingredients.
  • Whisk together the granulated sugar and cocoa powder in a medium saucepan until blended.  Add the milk and butter and set over medium high heat, stirring constantly until all the butter has melted and it's evenly mixed.
  • Bring the fudge mixture up to a full boil, keeping the pot uncovered.  Insert a candy thermometer and let the mixture cook until it reaches 230 F, stirring frequently, then immediately take it off the heat.
  • Stir in the peanut butter, vanilla extract, and pinch of salt until thoroughly mixed, then gradually add enough oats to get a thick and fudgy, but not dry, consistency.
  • Drop the mixture by rounded tablespoonfuls onto the prepared cookie sheets.  Allow them to harden at room temperature, about 35 minutes to 1 hour, then serve.  Store the no bake cookies in an airtight container at room temperature.


  • Guarantee a good batch by using a digital thermometer to see if the fudge mixture is cooked to 230 F.  Otherwise, the no bake cookies may be too gooey or too dry.
  • Want a different texture?  Use old-fashioned rolled oats for a chewier texture or quick oats for a smoother texture.
  • Substitute the peanut butter with almond butter, Nutella, or homemade sunflower seed butter.
  • Failed batch?  Freeze gooey ones, and crumble up dry ones and sprinkle on ice cream.
  • Store the no bake cookies at room temperature for up to 3 days or the freezer for up to 3 months.
