Equipment

  • 8x8 pan

Ingredients

  • 135 grams rice krispies
  • 56 grams unsalted butter
  • 283 grams marshmallows
  • 113 grams peanut butter melted
  • ½ teaspoon kosher salt
  • ¼ teaspoon vanilla extract
  • 40 grams pretzels chopped
  • 55 grams peanut butter cups chopped

Instructions

  • Line a 8x8 inch pan with parchment paper.
  • Cut your peanut butter cups and pretzels into ½ inch segments. Pour into a large bowl with the rice krispies.
  • In a microwave, melt the peanut butter for 20-30 seconds
  • Place butter in a large saucepan and melt. Allow the butter to begin to brown, with small brown flakes at the bottom. Add the marshmallows, vanilla and salt and stir until melted, about 3 minutes.
  • Pour the butter marshmallow mixture over the cereal, and then add melted peanut butter. Fold, but you don’t want to over mix as we still want thick swirls of peanut butter in the mix
  • Pour into the prepared pan. Using a spatula, gently press down. Don’t press down too hard or they’ll be too compact
  • Let sit at room temperature for at least two hours then slice

Notes

Butter: I use European style butter, like Kerry Gold, in my recipes. This will make your finished bake much creamier and richer.
Salt: If you don't have kosher salt, halve the amount of salt called for in the recipe. 1 teaspoon kosher salt = ½ teaspoon fine salt.
Storage: slice the treats into 16 bars and keep in an air tight container for up to 5 days. I do not recommend freezing these as it will alter the texture.

My recipes have been developed and tested in metric grams. I highly recommend using a weighing scale and measuring out your ingredients the metric way. I have provided a conversion to US cups but please note that I haven't tested the recipe with this method.
