Preheat the oven to 350° and have ready a greased, 8"x8" square baking dish.
Melt the butter in a microwave-safe pitcher or bowl, and set aside to cool.
In a medium-sized mixing bowl, combine flour, cocoa powder, baking powder, and salt. Whisk and set aside.
Add the eggs to a large mixing bowl, and whisk. Add the sugar and vanilla, and with a handheld mixer on medium speed (or a sturdy wooden spoon), mix until well combined. Slowly stream in the melted butter, mixing all the while.
Add the dry ingredients and slowly mix until just combined. Add in a ½ cup of the chocolate chips and mix once more.
Add the batter to baking dish, spread to the edges and smooth over the top.

To make the peanut butter swirl, add the peanut butter to a microwave-safe bowl, and microwave for about 30 seconds, just until the peanut butter has liquified.
Remove from the microwave and stir in the powdered sugar, vanilla, and salt until smooth.
Drop tablespoons-sized mounds of the peanut butter mixture across the top of the brownie batter. Use the tip of a sharp knife to swirl the peanut butter into the batter, ever so slightly digging into the batter in an up-and-over swirly motion. Sprinkle the top with the remaining ¼ cup of chocolate chips.

Bake for 35 minutes for a soft and chewy brownie or 40 minutes for a brownie with crispier edges and a more-done center.
