Equipment

  • 8×8 baking pan

Ingredients
 
 

  • ½ cup butter salted or unsalted
  • ½ cup brown sugar light
  • ¼ cup granulated sugar
  • ½ cup peanut butter smooth, Skippy or Jif
  • 1 egg at room temperature
  • 1 teaspoon vanilla extract
  • 1 cup AP flour
  • ¼ teaspoon salt
  • 7 nutter butter cookies roughly chopped, 3 extra ones for topping
  • ½ cup mini semi sweet chocolate chips 2 extra tablespoons for topping

Instructions
 

Make the brown butter

  • In a small heavy-bottomed saucepan, over medium heat, melt the butter, making sure to stir continuously. Continue cooking it for 3-5 minutes or until the butter is foamy and turns medium golden brown.
  • This process is called browning the butter. Keep a close eye on it because it can burn easily. Remove from the heat, transfer to a medium bowl, and let the butter cool down to room temperature. It doesn't have to harden.

Make the nutter butter blondie

  • Preheat the oven to 350F then line an 8×8 inch baking pan with parchment paper.
  • When the butter is at room temperature, mix the melted brown butter, peanut butter, granultated sugar, and brown sugar together on medium speed until combined.
  • Add the egg, and the vanilla extract and mix to combine.
  • Mix in the flour and salt just until the flour disappears. You don't want to over-mix the brown butter blondie mix. Fold in the chopped-up nutter butters, and chocolate chips.
  • Spread the dough mixture in the prepared 8X8 inch baking pan, top with roughly chopped up utter butter cookies, and some mini or regular chocolate chips, and bake for 20 minutes.
  • Once baked, pull out the bars from the oven and allow them to cool down fully before slicing into them. I let them cool for an hour or two depending on my kitchen's temperature. They should be at room temperature. This will allow the bars to be fully set. Slice into 16 equal squares and enjoy.

    The best fix to a pb craving! Made these last night to take to a friend. My regret is not making a double batch! Even with allowing the butter to cool, this recipe is fast & so easy. I will make again, possibly even this weekend … so good!

    Just made these substituted chocolate covered nutter butters for the regular. This recipe was so easy to follow and the results were absolutely yummy. Only change is I need to make a double batch next time because my family and myself already ate them all. Thank you for the great recipe
