These Peanut Butter Cookie Bars are SO good! They’re nice and chewy and packed with peanut flavor and dark chocolate chunks. The star of these cookie bars are the dark chocolate chunks. They add a bit of a sophistication to the humble peanut butter cookie bar.
I used dark chocolate in this recipe as opposed to milk chocolate because I like how the intense chocolate flavor cuts through the peanut butter. If you’re feeling super decadent, then I suggest sprinkling the top of the cookie dough with some chunky sea salt right before baking!
If you love the peanut butter and chocolate combination as much as I do, then you need to try some of my other recipes!

COOK’S NOTE – PEANUT BUTTER COOKIE BARS WITH DARK CHOCOLATE CHUNKS:
- Cooled and cut peanut butter bars can be stored in an airtight container at room temperature for up to 5 days.
- These peanut butter cookie bars are best served warm. I suggest heating individual cookie bars for 15 seconds at 50% power.
- You can double this recipe and bake the peanut butter cookies bars in a standard rimmed cookie sheet. You will need to increase the baking time by 4-8 minutes.
