  • Fold the krispies in 4-5 large strokes (we want there to be thick swirls, not completely mixed). Transfer it to a greased and parchment paper lined 9x13 large pan.
  • Use a rubber spatula to spread the krispies out into the prepared pan. Top with the remaining 2 tablespoons of melted peanut butter in a drizzle.
  • Allow to cool for an hour-ish, or transfer to the fridge/freezer to expedite the process. Cut into 16 squares to enjoy!
