Chewy Peanut Butter Cookie Bars Recipe

These Chewy Peanut Butter Cookie Bars are sweet, soft, chewy and SO peanut buttery! Bake the batch in one pan, so you get 36 bars all at once. No waiting for batches of cookies to bake when you make these bars!

I made the most delicious peanut butter cookie bar recipe for you! The. Most. Delicious. I seriously cannot stop eating these little bars of peanut butter deliciousness. Peanut butter is one of my biggest weaknesses, and combine it with a cookie batter, I can’t stop. Won’t stop. I hope you enjoy this easy cookie bar recipe as much as we do!

If you are a peanut butter lover, then you will love these Chewy Peanut Butter Cookie Bars. These cookie bars are sweet, soft, and so peanut buttery. Bake them in an 9 x 9 inch pan, then cut the cookie slab into about 36 squares. But really, you can cut them as big or small as you like. There’s just something so great about making cookies in an easy cookie bar form…everything is done and made in one batch.

If you like your cookies soft and chewy, the key is to slightly under bake them. The same tip applies to these peanut butter cookie bars. We LOVE our cookies and bars soft and chewy, and under baking them makes them just perfect.

Peanut Butter Cookie Bars Recipe Tips

  • PEANUT BUTTER: Use creamy peanut butter or crunchy peanut butter. I have never made these with natural peanut butter (or any other type of nut butter) so I’m not sure if that would work.
  • PEANUT BUTTER CHIPS: If you don’t have peanut butter chips, you can easily substitute them with chocolate chips (milk chocolate chips, semi-sweet chocolate chips or dark chocolate chips) or even Reese’s pieces or white chocolate chips…then you will have Peanut Butter Chocolate Chip Cookie Bars…yum!
  • ADD-INS: You can add chopped nuts too (chopped peanuts, pecans or walnuts).
  • STORAGE: Store these bars in an airtight container at room temperature for about 4 days. They will dry out if left out too long.
  • FREEZING: These cookie bars freeze well. Keep in an airtight container or plastic freezer bag in the freezer for up to 3 months.
  • SERVING IDEA: These delicious bars are perfect on their own, but if you want to serve them as a dessert, add a scoop of vanilla ice cream and you’ve got crowd pleaser dessert bars! Yum.
