There’s something irresistible about the nostalgic charm and aroma of freshly baked chewy oatmeal chocolate chip cookie bars. They take everything we love about classic chocolate chip cookies — melty chocolate, buttery richness, and sweet vanilla — and elevate it with the hearty chew of oats and the simplicity of a bar format. Unlike drop cookies that require batch after batch of scooping, these bars bake in one pan, slice beautifully, and are ready in under an hour.
According to recent baking trend reports, oat-based desserts have surged in popularity due to their health benefits and comforting texture. These chewy oatmeal chocolate chip cookie bars are a prime example of why. They’re soft yet sturdy, indulgent yet wholesome, and universally loved by adults and kids alike.

🧑🍳 Step-by-Step Recipe for Chewy Oatmeal Chocolate Chip Cookie Bars
1. Preheat and Line the Pan
Set your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, letting it overhang for easy lifting later. Lightly butter the sides if not using parchment.
2. Cream the Butter and Sugars
In a large mixing bowl, beat together the softened butter, brown sugar, and granulated sugar using an electric mixer until light and fluffy. This aerates the batter and creates the foundation for that chewy bite we crave in chewy oatmeal chocolate chip cookie bars.
3. Mix in the Wet Ingredients
Add eggs one at a time, beating well after each. Stir in vanilla extract. Make sure everything is well emulsified for even baking.
4. Combine Dry Ingredients Separately
In another bowl, whisk together flour, baking soda, and salt. Gradually add this dry mix to the wet ingredients and stir gently.
5. Add the Oats and Chocolate
Fold in the oats and chocolate chips. The dough will be thick and sticky — that’s perfect! For extra decadence, try mixing in chunks of dark chocolate or toasted pecans.
6. Bake to Golden Perfection
Spread the dough evenly in the pan. Bake for 25 to 30 minutes, or until the edges are golden brown and the center is just set. For extra chewy oatmeal chocolate chip cookie bars, remove when the middle still looks a bit soft — it will firm as it cools.
7. Cool, Slice, Enjoy
Let the bars cool in the pan for at least 10–15 minutes. Lift out with parchment and slice into squares. These chewy oatmeal chocolate chip cookie bars are at their best slightly warm or at room temperature.
