These Chocolate Peanut Butter Skillet Brownies have a rich, fudgey interior with peanut butter chips scattered throughout and are topped off with a peanut butter drizzle and vanilla ice cream!
Meanwhile, to make the peanut butter drizzle, combine the powdered sugar, milk, and peanut butter in a small bowl and stir until well combined (add additional milk if you want a thinner consistency.
Using a spoon, drizzle the peanut butter mixture over the brownies. You can also use a small Ziploc or pastry bag and cut off the end to drizzle.
Top with vanilla ice cream, if desired, and enjoy!
