Peanut Butter Brownies are rich, fudgy chocolate brownies stuffed with Reese’s Peanut Butter Cups and topped with a creamy peanut butter swirl. Every bite has that classic chocolate and peanut butter combination.

These brownies start with a boxed brownie mix, making them incredibly easy to put together. I first had them when my sister made them for Christmas, and I knew I had to make them myself.

Tips I Found Helpful 💙

  • Don’t overmix the batter – Mix the brownie batter just until combined.
  • Use a single layer of Reese’s – This gives you peanut butter in every slice without making the brownies too thick.
  • Warm the peanut butter – Melting it makes it much easier to mix with the powdered sugar and swirl.
  • Don’t overbake – Check the brownies around the 30-minute mark so they stay soft and fudgy.
  • Let them cool before cutting – The brownies will slice much cleaner once they’ve had time to set.

Questions Readers Ask Most

Yes. Crunchy peanut butter will work if you want a little extra texture.

Insert a toothpick near the center. It should come out with a few moist crumbs rather than wet batter.

Store the brownies in an airtight container at room temperature for up to 3 days or refrigerate them for longer storage.

  8. I don’t have a cast iron pan. Would it work the same with a regular pirex dish that I normally make my brownies in? Thank you!
