Published by Kate
No-bake cookies are a sweet treat straight from grandma's recipe box. Don't miss the marshmallows, which form gooey puddles (!) or the shredded coconut!

  • ½ cup milk
  • ½ cup salted butter (1 stick)
  • 2 cups sugar
  • 3 tablespoons unsweetened cocoa
  • 3 cups quick oats
  • ½ cup peanut butter
  • 1 teaspoon vanilla
  • 1 cup miniature marshmallows
  • ½ cup unsweetened flaked coconut
  • ½ cup chopped walnuts


  • Place the milk, butter, sugar, and cocoa in a medium saucepan. Place over medium heat and bring to a boil, whisking occasionally. Boil for 2 minutes. Remove from the heat. 
  • In a large bowl, combine the oatmeal, peanut butter, vanilla, mini marshmallows, coconut, and walnuts. Pour the liquid mixture over the top and stir to combine.
  • Drop 2 tablespoons of the mixture onto parchment paper. Repeat with remaining mixture to create approximately 24 cookies. 
  • Let cool for 1 hour before serving.


Make sure to drop the cookies onto parchment paper to ensure they don't stick! Wax paper or foil would also work. 
If you're using unsalted butter, add a half teaspoon of salt to the mixture. It'll balance the sweetness of the rest of the ingredients nicely.
