Oatmeal Chocolate Chip Cookie Bars are the ultimate blending of oatmeal cookies and chocolate chip cookies… made incredibly easy baked into bars. Oozing with melty chocolate, chewy and crisp with oats, and irresistible with a sprinkling of flaky sea salt.
They are… so good. And so easy.
If you bake a lot of cookies, you find yourself asking the family (all the time), “Chocolate chip or oatmeal?” when it’s cookie making time.
For me, it’s always a quandary because we love both (I love both!). And often those cookie baking sessions do produce the always popular oatmeal chocolate chip cookies.
But these Oatmeal Chocolate Chip Cookie Bars deserve their place on the cookie baking schedule too. They are just as crave-worthy as the regular cookies, but honestly, simpler and easier to make!
So for those times when you’re craving a warm from the oven cookie, try these!
What to Love About Oatmeal Chocolate Chip Bar Cookies
- Fuss-free and easy to make in 1 bowl, 1 pan, with a spatula.

Cookie Bar Ingredients
Go gather these ingredients to make the most delicious cookie bars… ever! The exact measurements are in the recipe card at the bottom of this post.
- Butter– melted for easy cookie making.
- Sugar– both brown sugar and granulated sugar are used for maximum flavor and texture.
- Eggs– I’m using 1 large egg.
- Vanilla extract– I can’t imagine any cookie without a splash of pure vanilla extract!
- Flour– All-purchase flour for this recipe, but if you want the cookie bars to be gluten-free, substitute all-purpose gluten-free flour.
- Baking powder and baking soda– for rise.
- Sea salt– For most baking, I find myself using fine sea salt for the best flavor. But I also love flaky sea salt and do sprinkle some on top of the bars too.
- Oats– Use old-fashioned oats. If you’re making them gluten-free, be sure to use gluten-free oats along with GF flour.
- Chocolate Chips– I’m using semi-sweet chocolate chips, which are always stocked in my pantry, but milk or dark chocolate would be super delicious too!
How to Make Oatmeal Chocolate Chip Bars
Much like making cookies, these bar cookies contain similar ingredients. But instead of dolloping mounds of cookie dough and baking individually, it’s made super easy by baking in one pan.
Here’s how I bake these bar cookies.
- Preheat the oven and line a square baking pan with parchment paper for easy removal.
- Melt the butter.
- Stir both sugars into the melted butter. Once combined, stir in the egg and vanilla.
- Add the flour, baking powder, baking soda, and salt; just until just combined.
- Fold in the oats and chocolate chips.
- Press cookie dough into the prepared pan – be sure to get them into the corners too!
- Bake until the bars are set and golden.
- Remove from the oven and sprinkle with flaky sea salt if desired. Let them cool before cutting into squares.

- 3/4 cup butter, cut into tablespoon pieces
- 1 1/4 cups packed brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 2 teaspoons vanilla extract
- 1 1/4 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon sea salt
- 1 cup old fashioned oats
- 3/4 cup semi-sweet chocolate chips
Preheat oven to 325 degrees F. Line a 9×9-inch square baking pan with parchment paper and set aside.
Place the butter in a medium saucepan and melt over medium heat, stirring often, until it foams, smells nutty, and browns. This will take about 5 to 7 minutes. Scrape the browned butter into a large bowl and let cool for 5 minutes.
Add the brown sugar and sugar to the brown butter and stir with a wooden spoon or spatula until smooth. Add the egg, and vanilla. Stir until combined.
Add the flour, baking powder, soda, and salt. Stir until just combined, don’t over-mix.
Stir in the oats and chocolate chips.
Pour the dough into the prepared pan and spread with a spatula. You can use your fingers to lightly press the dough into the corners of the pan to make sure the dough is evenly spread.
Bake for 25 to 35 minutes or until the bars are set and golden brown. Don’t over bake the bars will continue setting up as they cool.
Remove from the oven and sprinkle with flaky sea salt. Let the bars cool before cutting into squares.
