  • pot
  • Wooden spoon or Silicone Spoon
  • Silicone Mat or parchment paper
  • Sheet pan or cookie sheet


  • 1 3/4 cups of white granulated sugar 350g
  • 1/2 cup of milk 1%, 2%, Whole, etc. (125ml)
  • 1/2 cup of unsalted butter 115g
  • 3/4 cup of peanut butter 190g
  • 1 tsp. vanilla extract 5ml
  • 3 1/4 cups of old fashioned or quick oats 295g


  • Add the milk, butter, and sugar to a medium saucepot. With burner set to medium heat, bring the milk and sugar to a boil. After it comes to a rolling boil allow it to cook for 1 minute before removing it from the heat.
  • After you remove the pot from the heat pour it into a large bowl and then stir in the vanilla extract and the peanut butter. Once the peanut butter has melted, add in the oats. Stir the oats until completely coated.
  • Spoon the peanut butter oatmeal onto a cookie sheet lined with parchment paper or a silicone mat. They won't spread, so you can put them pretty close together. Shape the cookies with the spoons to get them more round if you like.
  • Chill the cookies in the fridge for at least 30 minutes until they have set. Enjoy!
