Easy Oat Flour Chocolate Chip Cookies

Why I Keep Coming Back to This Recipe

It was a rainy afternoon in early spring when I first made these oat flour chocolate chip cookies. My toddler had just gone down for a nap, the house was quiet except for the gentle patter of rain on the windows, and I was craving something sweet but wholesome. I remember rummaging through my pantry and realizing I was out of all-purpose flour. But there, tucked behind a jar of quinoa, was a nearly forgotten bag of oat flour. That moment sparked what would become one of my favorite cookie recipes — a soft, chewy, subtly nutty twist on the classic chocolate chip cookie.

That first batch was warm and gooey, rich with dark chocolate, and just hearty enough to feel like an afternoon treat I could feel good about. Since then, these have become a staple in our house. My daughter now requests them as her “cozy cookies,” and every time I make them, I’m brought back to that peaceful, rainy afternoon.

What Makes These Oat Flour Chocolate Chip Cookies Stand Out

Unlike traditional chocolate chip cookies that rely on all-purpose flour for structure, these cookies use finely ground oat flour, which lends a delicate, tender crumb and a mild, earthy sweetness. Oat flour also makes them naturally gluten-free — provided you use certified gluten-free oats — making them a perfect treat for those with sensitivities.

The texture is what gets me every time. They’re soft in the middle with crisp, golden edges, and the oat flour gives them this almost buttery smoothness without feeling heavy. Combined with generous chunks of semi-sweet chocolate and a sprinkle of flaky sea salt, they strike that magical balance between indulgence and comfort. If you’re into gluten-free baking, don’t miss these Coconut Flour Cookies — another soft, chewy treat with a wholesome twist.

Plus, they’re easy. No chilling required, no fancy equipment — just a bowl, a spoon, and a craving for something cozy and chocolatey.

Let’s Talk Ingredients

Oat flour is the star here. You can buy it pre-ground or make your own by blending rolled oats in a high-speed blender until fine. If making your own, be sure to sift it for a smoother texture in your dough. According to Healthline, oat flour is packed with fiber and has a lower glycemic index than traditional white flour, making it a smart choice for more balanced snacking.

Brown sugar is key for chewiness, while a bit of white sugar helps crisp up the edges. I use unsalted butter, but you can sub in coconut oil for a dairy-free version. An egg binds everything together, and a splash of vanilla deepens the flavor.

For chocolate, I lean toward chopped dark chocolate or high-quality semi-sweet chips. The irregular pieces melt into gooey pockets that make every bite a little different — in the best way.

How to Make Oat Flour Chocolate Chip Cookies

Mixing the Wet and Dry Ingredients

Start by creaming together the butter and sugars until smooth and slightly fluffy — about two minutes by hand or with a hand mixer. Add the egg and vanilla and stir until combined. In a separate bowl, whisk the oat flour, baking soda, and salt. Then, gently stir the dry ingredients into the wet, mixing just until no streaks remain. The dough will feel a bit softer than traditional cookie dough.

Fold in your chocolate — chips or chunks, your choice — and resist the urge to overmix. That’s it. Your dough is ready.

Baking and Finishing Touches

Scoop generous spoonfuls of dough onto a parchment-lined baking sheet, leaving space for spreading. Bake at 350°F for 9 to 11 minutes, just until the edges are golden and the centers look slightly underdone. They’ll firm up as they cool, staying irresistibly soft inside.

Once out of the oven, I like to press a few extra chocolate pieces on top and finish with a pinch of flaky sea salt. It elevates the whole experience — trust me.

Expert Tips, Swaps & Storage Advice

If you’re avoiding dairy, substitute the butter with refined coconut oil and use dairy-free chocolate chips. For egg-free cookies, a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water) works beautifully.

You can make the dough ahead and keep it chilled for up to 3 days, or freeze individual scoops on a tray before storing them in a zip-top bag. They bake beautifully straight from the freezer — just add an extra minute or two to the bake time.

Stored in an airtight container, the baked cookies stay soft for 4 to 5 days at room temperature, though they rarely last that long in our house.

What to Serve These With

I love these cookies with a cold glass of oat milk or a hot cup of coffee in the morning. They also pair wonderfully with a scoop of vanilla ice cream for an easy dessert. My husband’s favorite combo? A warm cookie sandwiched with a smear of peanut butter.

They’ve also made appearances at picnics, lunchboxes, and cookie swaps — always met with, “Wait, these are gluten-free?” They’re that good.

Common Questions

Can I freeze these cookies?

Absolutely. Freeze the unbaked dough or the fully baked cookies. If freezing baked cookies, let them cool completely, then store in a sealed bag. They thaw quickly at room temp or can be warmed in the oven for a few minutes.

What kind of chocolate works best?

While you can use any chocolate chips you have on hand, chopped dark chocolate creates melty, rich pools that I personally think take these over the top. For a kid-friendly version, semi-sweet chips are a safe and delicious bet.

Save It for Later
