Equipment

Ingredients

  • 12 oz white chocolate chopped bars or chips
  • cups creamy peanut butter 400g
  • 14 oz sweetened condensed milk 1 can
  • 6-7 oz marshmallow fluff
  • ¼ cup creamy peanut butter melted, for topping (80g)
  • cup roasted shelled peanuts for topping
  • flaky sea salt for topping

Instructions

  • Line an 8x8 inch baking pan with parchment paper and set aside.
  • In a large microwaveable bowl, add the white chocolate and peanut butter and microwave in 30 second bursts, stirring in between each, until the mixture is completely melted.
  • Add in the sweetened condensed milk and stir to combine. The mixture will start to thicken. Transfer to the baking pan and press it down and out so it almost meets the edges.
  • Add the fluff in dollops, working the fluff into the fudge and swirling as you push the mixture to the meet the sides and corners.
  • Drizzle the melted peanut butter over the top and use chopsticks or a toothpick to swirl it into the fluff.
  • Top the mixture with roasted peanuts and flaky salt.
  • Allow the fudge to set in the fridge for about 30 minutes, then slice into 16 pieces and serve.

Notes

Store the fudge tightly covered in the fridge for one week. The fudge is best enjoyed at room temperature, though. 
Chocolate chips have added ingredients that prevent melting. It's best to use a chocolate bar, however, if using chocolate chips, you may need to strain the mixture to remove any leftover chunks.
The peanut butter and white chocolate can also be melted over a double boiler.
Note the mixture will be very thick, so do your best to work some of the fluff into the fudge. It won't look appealing at this point. Adding the peanut butter drizzle and swirling in adds the aesthetics.
