  • 2 cups sugar
  • ½ cup brown sugar, packed
  • 4 tablespoons butter
  • ½ cup milk
  • 1 cup peanut butter
  • 1 cup mini marshmallows


  • Start by boiling both sugars, butter, and milk in a pot until it reaches 236°F, then immediately stop.
  • Add in the peanut butter and marshmallows and whip until it starts to thicken.
  • Pour into a buttered 8x8-inch pan. You could also line the pan with parchment paper to make it even easier to lift the fudge out if you’d like to.
  • It takes about one to two hours for the fudge to harden completely. Wait until cooled to room temperature and slice into squares.


  • Make sure you have a good candy thermometer to precisely measure the temperature of the mixture.
  • You could also line the baking dish with parchment paper or aluminum foil to make it even easier to take out if you’d like to.
  • To help cut the fudge after chilling, score a grid on the top of the fudge when it is barely set but still warm.
