Ingredients

  • 1 ½ sticks (12 tablespoons) unsalted butter
  • cup creamy peanut butter
  • 1 ½ cup packed brown sugar
  • 1 ½ cups all-purpose flour
  • 1 tsp baking powder
  • ½ tsp fine grain kosher or sea salt
  • 1 tsp vanilla extract or paste
  • 2 large eggs, lightly beaten
  • ½ cup chocolate chips (whatever you like most. I used milk chocolate this time)
  • ½ peanut butter chips (optional, but delicious. If you can’t find them just add another ½ cup of chocolate chips)
  • 8 - 10 peanut butter cup candies

Instructions

  • Preheat oven to 350°. Spray an 8x8” baking pan with non-stick spray. Line the pan with parchment paper, leaving some paper to hang over the sides to use as a handle for lifting out the blondies later. Spray the parchment with non-stick spray as well. Set aside.
  • In a small bowl whisk together the flour, baking soda and salt. Set this aside too.
  • In a medium saucepan (big enough to add your dry ingredients to later), melt the unsalted butter. Allow to cool for a few minutes, then stir in the peanut butter. Add the brown sugar and whisk together until fully combined. Add the vanilla and eggs and whisk until they are completely incorporated.
  • Add the dry ingredients into the wet ingredients, being careful not to over mix. Just barely fold everything together until there are no more streaks of flour. Fold in the chips. Pour the batter into your prepared pan and smooth the top. Scatter the chopped peanut butter cups over the top and lightly press into the batter.
  • Bake at 350° for 25-30 minutes or until the top is a lightly golden brown. A toothpick or skewer inserted in the middle should come out with just a few crumbs. Let cool on a wire rack for at least an hour. Go do a puzzle or watch an episode of that show. Remove from the pan (using your handy dandy parchment handles 😊) and either allow to cool completely or go absolutely mad and just start munching.
