1Preheat oven to 375°. Line a muffin pan with 12 paper liners.
2In a medium bowl, whisk together the flour, baking powder, salt and brown sugar. Set aside.
3In a large bowl, whisk together the melted butter, peanut butter, eggs and milk until smooth. Add in the flour mixture and stir until just combined. Stir in chocolate chips. Divide batter evenly between prepared muffin tins, filling each to the top.
