Grease a 13x9" baking pan with oil or butter and line the bottom with parchment paper.
In a large bowl, whisk together the 2 ½ cups oat flour, ¾ teaspoon fine sea salt, ¾ teaspoon baking powder, and ¾ teaspoon baking soda.
Melt the ¾ cup unsalted butter and let cool slightly. Then whisk in the 1 cup packed dark brown sugar, ½ cup granulated sugar, and 1 tablespoon vanilla extract until the sugar slightly dissolves. Whisk in the 2 large eggs one at a time until smooth.
Stir in the dry ingredient mix until a soft dough forms. Fold in the 1 ½ cups semisweet chocolate chips.
Spread the dough into the baking pan, using your hands or a rubber spatula to press it out into an even layer. Preheat the oven to 325°.
Rest the dough while the oven heats, then place the pan in the oven and bake until the top is golden brown and a tester inserted into the center comes out clean apart from any smudges of melted chocolate, 30–35 minutes.
Let cool in pan at least 1 hour before cutting into an 8x3 grid to make 24 rectangles.

Make them dairy-free - Swap your favorite non-dairy butter for the butter.
Egg substitute - I haven't tried to make these cookie bars with an egg substitute, but you could try 2 flax eggs in place of the eggs.
Go refined sugar-free - Instead of brown sugar and granulated sugar, use coconut sugar to make these bars refined sugar-free.
Rest the dough - As in all gluten-free bakes, dough or batter benefits from a short rest before it's baked to hydrate the flour. This is easily accomplished by letting the chocolate chip cookie bar dough rest in the pan while the oven preheats. Try not to skip this step - it really does help!
Add-ins - You can add to this recipe by stirring in some chopped walnuts or pistachios, 1 cup of unsweetened flaked coconut, chopped candy, and more.
Other chocolate options - A classic chocolate chip cookie features semisweet chocolate chips, and my recipe includes them as well. However, you can use milk chocolate chips, mini chocolate chips, white chocolate chips, a combination, chopped chocolate from your favorite chocolate bar, or M&Ms!
Salt - There's a good amount of salt in these bars, and if you like a sweet-salty combo, I encourage you to add up to 1 teaspoon of fine salt. Alternatively, you could lower the salt a bit if you like less of a salty flavor. And, you can always scatter flaked sea salt over the top of the bars!
