Two amazing flavors combine to make these super easy and delicious Peanut Butter Chocolate Chip Cookie Bars. With easy ingredients and short on time, this is a perfect bar recipe.

Three stacked Chocolate Chip Cookie Bars.

I’m obsessed with the combination of peanut butter and chocolate chips and these Cookie Bars do not lack in that are at all. These chocolate chip cookie bars are perfect with peanut butter, peanut butter chips, and chocolate chips.

Cookie Bars are super fun and easy, quick to whip up, and require minimal time and effort. This recipe is perfect any time of year and for any type of function.

I love recipes that you can make whenever you want. They are perfect for gatherings, bake sales, or just because you want some sweets around the house.

These Chewy Chocolate Chip Cookie Bars really are what the name states; they are soft and chewy cookies turned into bar form.

If you don’t want to make individual cookies but want that cookie flavor, chewy Cookie Bars are the perfect compromise. I think they’re better than regular cookies.

These are a staple in our household, and we make lots of different flavors, but peanut butter and chocolate trump pretty much any flavor, in my opinion.

Once you try these chocolate chip cookie bars, they will automatically become part of your dessert rotation—and I’m not being biased on that one—just wait until you make them yourself!

Some of my other favorite bar/blondie desserts we have on our site include: Cinnamon Roll Blondies, Carmelitas and Lemon Bars.

FREQUENTLY ASKED QUESTIONS ABOUT THIS RECIPE:

Peanut butter cookie base loaded with peanut butter chips and chocolate chips!

This is the perfect treat for the peanut butter with chocolate lover.

Way easier than making a bunch of small cookies, just mix, bake, and cut! 

The cookie bars are thick, slightly crisp on the outside, and soft and chewy on the inside. 

If you like more of a gooey center, under-cook these for about 5 minutes.

If you want to use crunchy peanut butter, you can use it in place of the creamy peanut butter 1:1.

If you don’t want peanut butter in the cookie batter, just replace it with an equal amount of more butter.

You better believe it!

It’s always a good idea to experiment.

It’s a great way to upgrade any simple recipe.

  • Instant Espresso Powder: Add a teaspoon of instant espresso powder to the batter for enhanced chocolate flavor in your chocolate chip cookie dough.
  • Flaky Sea Salt: Sprinkle flaky sea salt on top of these peanut butter chocolate chip bars before baking for a sweet and salty combo that complements the semisweet chocolate chips.
  • White Chocolate Chips: Add 1 cup of white chocolate chips for a triple chocolate treat and an extra layer of sweetness.
  • Dark Chocolate Chunks: Mix in dark chocolate chunks for a richer, more intense chocolate flavor.
  • Chopped Nuts: Fold in 1 cup of chopped nuts like walnuts or pecans for added crunch and extra flavor.
  • Toffee Bits: Add 1 cup of toffee bits for a buttery, caramel-like addition that pairs well with the peanut butter.
  • Shredded Coconut: Mix in 1 cup of shredded coconut for a tropical twist and an interesting texture.
  • Cinnamon: Add 1 teaspoon of cinnamon to the flour mixture for a warm, spiced flavor that enhances the cookie bars.

Though I do think this is the perfect recipe for cookie bars, feel free to try out these ideas!

  • Crunchy Peanut Butter: Use crunchy peanut butter instead of creamy for added texture in the cookie dough.
  • Natural Peanut Butter: For a more wholesome option, substitute regular peanut butter with natural peanut butter, though this may slightly affect the texture.
  • Butter Substitute: For a dairy-free option, use margarine or a plant-based butter substitute without sacrificing the rich, buttery flavor.
  • Almond Butter: Swap peanut butter with almond butter for a different nutty flavor and to cater to peanut allergies.
  • Gluten-Free Flour: Use a gluten-free all-purpose flour blend in this chocolate chip cookie bar recipe instead of regular flour to make these bars gluten-free.

These can be stored in an airtight container where they will keep at room temperature for up to 5 days.

They can also be frozen, to do this you can individually wrap the bars in plastic wrap and place them in a freezer container where they will keep for up to 3 months.

To defrost, you can either place it on a countertop or in the refrigerator overnight until thawed.

DANA’S TIPS AND TRICKS:

  • You can halve this recipe if you’d like and bake in a 9×9-inch pan.
  • Use any of your favorite chocolate chips, we use semi-sweet but milk and dark chocolate will also work.
  • Other mix-ins can be added, see above for ideas.
  • You can use crunchy peanut butter instead of creamy if you’d like.
  • If you want less of a peanut butter flavor you can leave it out of the batter, see above on how to replace it.

  • These can be frozen, see above on how to do that.

  7. Girlfriend these are calling my name too. I want to make some.

  8. Thank you so much for linking this recipe up at Recipe Sharing Monday! The new link party is up and I’d love to see you back. Have a great week. 🙂

  9. Let’s talk about how amazing these look…I mean COME ON! I am seriously obsessed with anything that has peanut butter in it and these bars are so over the top scrumptious looking…I can’t stand it! Thanks for linking up at TGIF link party!!

  10. Quick question, this may sound stupid but is it two bags of chocolate chips and peanut butter chips or one bag of each mixed together?

  11. Definitely not stupid, I should have worded it better. I bought the bags where the peanut butter and chocolate chips are already mixed together. So you can just do like I did and buy those pre-mixed bags or get one peanut butter bag and one chocolate chip bag. Hope that makes sense!
