Instructions

  • Preheat oven to 425 degrees F and grease a standard 12-slot non-stick muffin tin with cooking spray. Set aside.
  • In a large bowl, whisk together brown sugar, peanut butter, and butter until smooth, then whisk in buttermilk, eggs, and vanilla until incorporated.
  • Add in flour, powdered peanut butter, baking powder, baking soda, and salt, then fold in with a rubber spatula until *just* combined.
  • Gently stir in peanut butter chips.
  • Divide batter evenly into the prepared muffins slots, then top with additional peanut butter chips and raw sugar, if desired.
  • Bake in preheated oven for 5 minutes.
  • Keeping the muffins in the oven, lower heat to 350 degrees F and bake for an additional 15 minutes or until an inserted toothpick comes out practically clean (it’s ok if a few crumbs stick).
  • Cool slightly, then remove from muffin tin and enjoy!
