Peanut Butter and Jelly Fudge

16 2-inch squares

If fudge is overcooked, even a little, it will be dry and crumbly; it's always better to err on the side of undercooking. To ensure success, remove fudge from heat just before it reaches the soft-ball stage.


  • 2 tablespoons unsalted butter, chilled, plus more for pan

  • 3 tablespoons light corn syrup

  • 1 cup granulated sugar

  • ¾ cup packed light-brown sugar

  • ¾ cup milk

  • 1 pinch baking soda

  • ½ teaspoon salt

  • 6 tablespoons creamy peanut butter

  • 1 teaspoon pure vanilla extract

  • 2 tablespoons red-currant or Concord grape jelly


  1. Lightly butter an 8-inch-square baking pan and set aside. Combine corn syrup, both sugars, milk, baking soda, and salt in a medium-heavy saucepan. Bring to a boil over medium-high heat, stirring occasionally. Insert a candy thermometer. Cook, stirring frequently, until temperature registers 236 degrees (just below soft-ball stage); don't overcook.

  2. Immediately remove saucepan from heat, and add chilled butter, then peanut butter and vanilla, stirring until smooth. Pour the mixture into prepared pan. Set aside in a cool, dry place, and let fudge set.

  3. Before the fudge cools completely, cut into desired shapes. Using a small melon baller, scoop out a small hole in the center of each fudge shape. Set shapes aside to cool completely. Fill a resealable plastic bag with jelly; close, and cut off a corner. Squeeze the jelly into holes. Store fudge in an airtight container up to one week.
