   Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish.

   Beat peanut butter, sugar, butter, flour, vanilla extract, and 1 egg together in a bowl with an electric mixer until thoroughly combined. Spread half the brownie batter into the bottom of the prepared baking dish and top with 1/4-cup dollops of peanut butter mixture in an even pattern. Pour remaining brownie batter between the dollops. Use a knife to lightly swirl the peanut butter mixture into the brownie batter; do not overmix.
