Ingredients:

  • 16 oz creamy peanut butter
  • 1/2 cup unsalted butter, cubed
  • 14 oz sweetened condensed milk
  • 1 tsp pure vanilla extract
  • 1/2 tsp sea salt
  • 3 cups powdered sugar, sifted

Instructions:

  1. Line an 8x8 inch square baking pan with parchment paper, leaving an overhang on two sides to act as a sling for easy removal.
  2. In a medium heavy-bottomed saucepan over medium-low heat, combine the cubed butter and sweetened condensed milk. Stir constantly until the butter is fully melted and the mixture is steaming, but do not allow it to reach a boil.
  3. Remove the saucepan from the heat. Whisk in the creamy peanut butter, vanilla extract, and sea salt until the mixture is completely uniform and glossy.
  4. If using powdered sugar for a firmer set, gradually fold it into the peanut butter mixture until fully incorporated and no white streaks remain.
  5. Pour the mixture into the prepared pan and smooth the top with a silicone spatula. Allow to cool at room temperature, then refrigerate for at least 2 hours until firm before slicing into 36 squares.
