Ingredients

  • 1 stick (8 tbsp) salted butter
  • 1 cup dark chocolate peanut butter cups, chopped 
  • 2 large eggs
  • 1/4 cup creamy peanut butter 
  • 2/3 cup granulated sugar
  • 1/3 cup brown sugar
  • 1 tsp vanilla extract
  • 1 and 1/3 cup all purpose flour
  • 1/4 tsp salt

Instructions

  1. Preheat the oven to 350 degrees.

  2. Add the stick of butter and peanut butter to a bowl. Microwave for 30-40 seconds and then stir until it's fully melted and stir until smooth. Let this cool for a couple of minutes.

  3. In a large bowl, add the 2 eggs, vanilla extract, granulated sugar, brown sugar and salt. Whisk together for about 10 seconds, until combined.

  4. To this mixture, add in the peanut butter/butter mixture and mix until fully combined.

  5. Next, add in the flour. Mix with a large spoon (not whisk!) until it's fully combined. The texture should be like very thick frosting. 

  6. To the batter, gently fold in about 2/3 cup of the chopped peanut butter cups.

  7. Line an 8x8 glass baking dish with parchment paper.

  8. Add the batter directly to the pan, spreading it out evenly. Top with the extra PB cups.

  9. Bake for 35-40 minutes.  If you stick a toothpick in the brownies, it still might not be fully clean but that's okay because the brownies will continue to cook longer in the pan after you take them out. This is what makes them extra fudgy! Note: If you overbake them - they will be dry and cakey. Please trust me on this one!

  10. Let them cool in the pan for 10 minutes and then gently remove them onto a cooling rack.

  11. Let cool for another 10-15 minutes and then slice them into cookie bars. Top with flaky sea salt if desired and enjoy!
