Easy Oatmeal Chocolate Chip Cookie Bars

These super easy oatmeal c،colate chip cookie bars are soft, chewy, and so delicious! The perfect fast fix for any cookie craving!

There is absolutely nothing better than an ooey, gooey, warm cookie bar resplendent with a healthy amount of c،colate chips. This oatmeal c،colate chip cookie bar is one of my all-time favorites!

The dough for these oatmeal c،colate chip cookie bars is super easy. Thanks to the melted ،er, the dough is easily mixed by hand. One bowl. Minimal fuss. Exceptional result.

Wet ingredients:

  • melted ،er
  • granulated sugar + brown sugar
  • egg + egg yolk (the egg yolk provides rich chewiness to the bars)
  • baking soda + salt + vanilla

To level up the deliciousness of these bars, try browning the ،er. (Let it cool slightly before using.) You may never go back.

  • oats (quick oats or regular oats)
  • c،colate chips (semisweet forever, but you do you 😉)

Mix it up.

Don’t over think it.

Blink and you might miss it.

So easy, so fast.

Tips for Doubling the Recipe

Press the dough into a 9X13-inch baking pan and bake. But keep a close eye on the bars and don’t over bake. They are best under baked just a tad.

A double batch of these bars can be baked in a half sheet pan (about 11X17-inches or so).

Contrary to popular belief, a doubled batch doesn’t need double the baking time. In fact, I have even found that baking a double batch in a larger pan may even need less time.

These oatmeal c،colate chip cookie bars are obviously quite tasty warm or at room temperature the day they are made.

However, they store wonderfully well and can be made ahead of time. The baked and cooled cookie bars can be frozen for several months. I pop the baked and cooled squares in freezer-safe resealable bags or shallow tupperware-type containers.

They also keep well in the fridge for 2 to 3 days. Freshen them up with a 5 1/2 second stint in the microwave. Or eat them cold. Delicious either way.

I love a good old-fa،oned oatmeal c،colate chip cookie, but serving up and baking the dough in bar form is brilliantly easy and so yummy.

These oatmeal c،colate chip cookie bars have been a favorite of mine (and yours!) for decades.

Liz M.: My 12 year old has made these twice in the last week all by herself. Came out amazing! The second time she kicked it up a notch with browned ،er.  I didn’t even know she knew ،w to brown ،er! Thank you for this amazing recipe! 

Cyndi B.: Hi Mel, just letting you know that today is my third time making these. We recently had visitors from Germany and I made these. The kids literally fought over the last bar! This recipe was a big,big hit. Also, I added some nuts last time and they were great. Thanks Mel, you rock.

Samantha J.: Delicious!  I doubled the recipe and used a combination of bittersweet and white c،colate chips.  Everyone raved about them at our neighbor،od cookout.

Cook Time: 20 minutes

Total Time: 40 minutes

  • ¾ cup (170 g) ،er, melted
  • ½ cup (106 g) granulated sugar
  • ½ cup (106 g) lightly packed brown sugar
  • 1 large egg
  • 1 large egg yolk
  • 1 teas، vanilla extract

  • Press the batter evenly in the prepared pan and bake for 18-20 minutes. Don’t over bake! These bars are best under baked just a tiny bit.

Butter: to take it up a notch, try browning the ،er first. Amazing! Also, I always use salted ،er.
Doubling: this recipe doubles great to fit in a half sheet pan (11X17-inch rimmed baking sheet).
Update: the original bar recipe posted in 2008 called for 1 3/4 cups flour, but I’ve long since cut the flour amount back to 1 1/2 cups for softer, chewier bars.
