A batch of Peanut Butter Chocolate Chip Cookie Bars

Is there even a better flavor combination than chocolate and peanut butter?  I’m not sure that there is, and any recipe that combines these two flavors is a winner in my book.

So, it probably won’t surprise you that these peanut butter chocolate chip cookie bars are among my latest baking obsessions.  Recently I’ve been going through peanut butter like mad (fortunately I’d stocked up on jars over the holidays when I made dozens and dozens of peanut butter blossoms and a pan of peanut butter lasagna!), and the craze has continued as I’ve been making a batch of peanut butter chocolate chip cookie bars once a week.

They’re soft and chewy, made with a dash of cornstarch and creamy peanut butter (I don’t recommend using natural peanut butter).  These cookie bars can be made with milk, semisweet, or dark chocolate chips (or even white chocolate chips, it just depends on your chocolate preferences, I always prefer semisweet chocolate).

While I love a great chocolate chip cookie, these peanut butter chocolate chip cookie bars might be even better, and not just because they add peanut butter into the mix.

How to Make Peanut Butter Chocolate Chip Cookie Bars

Making the dough is as simple as making classic cookie dough, but the actual production requires half the effort because there’s no need to scoop the cookie dough into even-sized balls, wait to cook pan after pan of cookie dough, and repeat over and over until all of the cookie dough is gone.

Also, unlike with so many of my favorite cookie recipes, there’s absolutely no chilling required to make these cookie bars.  Just spread the batter into the pan and you’re good to go!

This recipe can be made in a 13×9 pan if you prefer, but I like to bake it in my smaller 9×9 pan instead for extra thick and chewy peanut butter chocolate chip cookie bars (like I said… big peanut butter & chocolate fan over here, so the bigger and fatter the squares the better!).

Keep in mind that if you do opt for the larger pan you will need to shave five minutes or so off of the cook time, as the thinner bars will bake much faster than their deep dish counterparts.
