  • 1 cup white sugar
  • ½ cup light corn syrup
  • 1 ½ cups peanuts, or more to taste
  • 1 tablespoon butter
  • 1 teaspoon baking soda
  • 1 teaspoon vanilla extract


  1. Spray a baking sheet and a wooden spoon with cooking spray.
  2. Mix sugar and corn syrup together in a microwaveable bowl safe for high temperatures.
  3. Heat sugar mixture in microwave on high for 5 minutes.
  4. Stir peanuts and butter into sugar mixture. Heat in microwave until mixture becomes a caramel color, 3 to 4 minutes.
