Prep Time 10 minutes
Cook Time 10 minutes
Total Time 20 minutes
Servings 20 squares

Ingredients

  • 1 cup sugar
  • 1 cup brown sugar firmly packed
  • ¾ cup milk
  • 2 tablespoons corn syrup
  • 2 ounces bittersweet chocolate chopped
  • 3 tablespoons unsalted butter
  • pinch salt
  • 1 teaspoon vanilla extract
  • cup peanut butter creamy
  • ¾ cup mini marshmallows or large ones cut into bites

Instructions

  • Line an 8-inch (20cm) square pan with parchmente paper or aluminum foil.
  • In a heavy medium saucepan, combine 1 cup sugar, 1 cup brown sugar, ¾ cup milk and 2 tablespoons corn syrup.
  • Add 2 ounces bittersweet chocolate and cook over medium heat, stirring constantly, until the mixture boils. Attach a candy thermometer and let it boil slowly, stirring occasionally, until it reaches 236ºF/113°C, or soft ball stage.
  • Remove from the heat, add 3 tablespoons unsalted butter on top, but don't stir. Let cool to lukewarm (110ºF/43°C), like warm tap water.
  • Add pinch salt, 1 teaspoon vanilla extract, ⅓ cup peanut butter and mix well. Add ¾ cup mini marshmallows and pour into the prepared pan, spreading evenly.
  • Put in the fridge until cold. Cut into squares and serve.
  • Keep refrigerated, well wrapped.

Notes

Saucepan: make sure it has high sides, about 4 inches, to let the mixture climb up while cooking.
Add-ins: you can also add a handful of peanuts, pecans, or walnuts. Decrease the marshmallows by ⅓ cup and add the same amount of nuts.
