My daughter loves brownies and usually she will make brownies at least twice a week! I love brownies but I also love cookies. This is the best of both worlds.

These little bars have so much flavor and it will satisfy any sweet tooth craving. I seriously think that homemade treats like these are SO much better than what you can buy at any cookie store!




  • PEANUT BUTTER: I used smooth peanut butter but crunchy would be fabulous!
  • BROWNIE: The brownie batter is a simple mix but you can substitute a brownie mix instead.
  • STORAGE: Leftovers can be kept in an airtight container for up to 3 days. You can also freeze these little gems in an airtight container for up to 3 months. 
  • DO NOT OVER MIX: When your mixing remember, less is more! You don’t want to over work the batter.
  • BUTTER: Brown the butter! Seriously, it makes such a difference to the flavor of your dessert. What does it mean to brown the butter? When melting the butter, let it cook a little longer, while stirring, until it becomes a caramel color.
