Print Recipe


  • 1 cup dry-roasted peanuts
  • 1 cup 200gr sugar
  • 1/8 teaspoon salt
  • ½ cup light corn syrup
  • 1 tablespoon margarin*
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon baking soda


  • First check your microwave power. (Mine was written at front when you open the door.) The time directions in this recipe for microwaves with 1000Watts.
  • Measure and prepare all the ingredients before moving forward.
  • Prepare a baking sheet and spray with non-stick spray.
  • In 1-quart microwave-safe bowl with a lid (stay away from plastic container though, I prefer a glass bowl), combine peanuts, sugar, salt and corn syrup.
  • Cover the bowl and microwave the mixture for 3 minutes. (Leo’s tip: If you don’t cover the mixture, it’ll get burnt.)
  • Take it out and give it a nice stir.
  • Then cover and microwave for another 3.5 minutes.
  • Take it out and stir in margarine and vanilla extract.
  • Cover and microwave again for 2.5 minutes.
  • Take it out and add baking soda.
  • Quickly stir, as the mixture foams.
  • Pour the mixture onto the prepared baking sheet.
  • Using 2 forks, spread it out into even layer.
  • Let it cool and harden, about 30-45 minutes. Store in a ziplock bag for up to a week.

*You can’t substitute butter for margarin. I tried and got rock hard brittles.
