- 2 1/2 cups white sugar
- 2/3 cup light corn syrup
- 1/3 cup water
- 2 egg whites
- 1 tablespoon confectioners' sugar, or as needed
- 1/2 cup peanut butter, or as needed
- Mix sugar, corn syrup, and water together in a deep pan; bring to a boil. Heat to 250 degrees F (120 degrees C), or until a small amount of syrup dropped into cold water forms a rigid ball (hard ball stage), about 15 minutes.
- Beat egg whites in a glass or metal bowl until stiff peaks form. Lift your beater or whisk straight up: the egg whites will form sharp peaks.
- Slowly pour sugar mixture over egg whites while beating with an electric mixer. Beat until candy clings to a spoon and loses some of its shine. Spread candy mixture onto a sheet of waxed paper; sprinkle with confectioners' sugar. Generously spread peanut butter over candy mixture. Roll candy into one large roll; cut into 2 rolls. Slice each roll into desired pieces.
