Perfectly chewy and dense, these High Altitude Chocolate Chip Cookie Bars are my current jam. I made them no less than a dozen times over the summer and they received rave reviews every single time I shared!

I love a simple chocolate chip cookie. In fact, aside from pie, it’s my dessert of choice. You just can’t beat a perfect chocolate chip cookie. So much beauty in it’s simplicity, you know? I guess that’s why you’ll find so many chocolate chip cookie recipes on my site! But lately I’ve found myself making cookie bars instead. It’s not like making a batch of cookies is tough or anything but bars are SO much less time intensive. So I guess they seem easier. I’m not tethered to the oven and the bars are just as tasty as a cookie in my opinion.

Apparently my boys and their friends would agree. You know the old adage ‘eating me out of house and home’? I’m starting to get it. Both the boys had playdates last Friday and between the 5 boys, they went through 1/2 gallon of milk, 3/4 bag of gold fish, 4 bananas, 3 apples and 1/2 a pan of these cookie bars. You guys. I can’t even. They’re eating food like it’s their life’s work. I can’t imagine what it’s going to be like when they’re teenagers. Sheesh!

One of the little boys just happened to be here the last time I made these and he felt like he’d hit the jackpot! He told my son that he’s “so lucky” his mom is always making chocolate chip cookies. It’s so not the case but I let him believe otherwise, taking any extra credit I can. Even if it’s a bit of a stretch!

Like any high altitude baking, it’s a whole lotta trial and error until you find the perfect recipe and then spend time and money tweaking the recipe until you get it to work in your kitchen. These bars bars were no different. I love this recipe because it’s heavy on the brown sugar which creates a chewier, more flavorful cookie. The extra egg yolk gives a little bit of richness and moisture. I like that the bars are dense and chewy in the middle but the outsides are a little more crispy and cookie like. Obviously you could swap the mini chips for regular chips or even chunks of your favorite chocolate bar but I like how the mini chips ensure a little bit of chocolate in every bite!

    UGHHH I live in Denver and love baking. I was diagnosed with Celiac disease last year and it sucks trying to figure everything out haha. These look amazing, if I try them with some kind of gluten free flour I’ll check back in. 🙂

    Thank you for an outstanding bar cookie.  This heavenly sweet treat is soft & chewy. At 26 minutes they were barely barely starting to brown on tops & edges.  I took a leap of faith & removed them from the oven.  Just over 1 hour later they were almost cool & I cut them, smaller then suggested, into 48 bite size pieces.  Beyond amazing.  So much less labor then drop cookies.  Can see these often in my future.
