Tips from leigh Anne
- Use regular creamy peanut butter. Brands like Jif or Skippy work best for these peanut butter chocolate chip bars. Natural peanut butter that separates can affect the texture of the bars.
- Line your loaf pan with parchment paper. Leave a little overhang on the sides so you can easily lift the bars out of the pan once they’ve cooled.
- Don’t overbake. The secret to soft and chewy peanut butter cookie bars is to remove them from the oven when the edges are lightly golden brown and the center is just set. They will continue to firm up as they cool.
- Add extra chocolate chips. If you like, sprinkle a few extra chocolate chips over the top of the dough before baking. It makes the bars look pretty and gives you a little extra chocolate in every bite!
- Let them cool before cutting. I know it’s tempting to dig right in, but allowing the bars to cool will help them hold together when sliced.
- Warm them up. For that fresh-from-the-oven taste, pop a bar in the microwave for a few seconds. The chocolate gets nice and melty again!

Frequently Asked Questions
Can I use crunchy peanut butter instead of creamy?
Yes! Crunchy peanut butter works well if you like a little extra texture in your bars. I recommend using a regular commercial brand rather than natural peanut butter for the best results.
How do I know when peanut butter chocolate chip cookie bars are done?
Look for lightly golden edges and a center that appears just set. The bars may look slightly soft in the middle when you remove them from the oven, but they will firm up as they cool. Overbaking can make them dry instead of soft and chewy.
Can I use a different kind of chocolate chip?
Absolutely! Semi-sweet chocolate chips are my favorite because they balance the sweetness of the peanut butter cookie dough. Milk chocolate, dark chocolate, or even peanut butter chips would also be delicious.
Can I freeze leftover cookie bars?
Yes! These bars freeze beautifully. Wrap the cooled bars individually in plastic wrap and place them in a freezer-safe bag or container. Freeze for up to 3 months. When you’re ready to enjoy one, let it thaw at room temperature or warm it briefly in the microwave.
How do I store leftover small batch peanut butter chocolate chip cookie bars?
Keep the bars in an airtight container at room temperature for up to 3–4 days. Make sure they are completely cooled before storing so they don’t become soggy.
