Rich, indulgent, and satisfyingly chewy, these Chocolate Oat Cookie Bars are the ultimate treat for dessert lovers. Crafted with wholesome rolled oats and loaded with gooey semi-sweet chocolate chips, these bars strike the perfect balance between hearty and decadent. A hint of vanilla and the optional addition of crunchy nuts like walnuts or pecans elevate the flavor, while the buttery dough bakes to golden perfection in under 30 minutes. Whether you’re hosting a cozy gathering or craving a quick make-ahead snack, these cookie bars are easy to prepare and guaranteed to impress. Perfect for sharing—or keeping all to yourself!
Preheat your oven to 175°C (350°F) and line a 9x9-inch baking dish with parchment paper, leaving an overhang to make removing the bars easier.
In a large microwaveable bowl, melt the unsalted butter. Allow it to cool slightly so it doesn’t cook the eggs when added.
Stir in the brown sugar and granulated sugar until well combined and smooth.
Add the eggs and vanilla extract to the butter-sugar mixture. Mix until fully incorporated and the mixture is creamy.
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
Fold in the rolled oats, semi-sweet chocolate chips, and chopped nuts (if using) until evenly distributed.
Spoon the dough into the prepared baking dish, spreading it out evenly with a spatula.
Bake in the preheated oven for 20-25 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few crumbs.
Remove from the oven and allow the bars to cool completely in the pan before lifting them out using the parchment overhang.
Once cooled, cut into 16 equal squares or bars. Serve and enjoy!
