Oatmeal Cookies with Old-Fashioned Oats, Brown Sugar and Butter

Bake chewy homemade oatmeal cookies with old-fashioned oats, brown sugar and butter. Follow easy steps, ingredient tips and baking times for perfect results.

Oatmeal cookies are classic drop cookies characterized by a tender-chewy crumb and subtle nutty flavor derived from rolled oats blended with all-purpose flour, butter, brown and granulated sugars, and eggs. A small amount of baking soda leavens the dough, while vanilla extract and optional warm spices such as cinnamon enhance aroma; common mix-ins include raisins, chocolate chips, or chopped nuts for added texture and sweetness. Baked until the edges are lightly crisp and the centers remain soft, these cookies deliver a balanced combination of whole-grain heartiness and familiar dessert indulgence. Oatmeal cookies are typically served as an everyday snack, lunch-box treat, or casual dessert, and are especially popular during colder months and festive gatherings when homemade baked goods are in demand.

Notes

Chef’s Note: For deeper flavor, toast the rolled oats in a dry skillet until lightly golden before folding them into the batter—it adds a subtle, nutty crunch. If you like a thicker, chewier cookie, chill the portioned dough for at least 20 minutes; the colder butter slows spread in the oven. Finish the warm cookies with a pinch of flaky sea salt to sharpen the caramel notes.

Frequently Asked Questions

Can I use quick-cooking oats instead of old-fashioned rolled oats in this oatmeal cookie recipe?
Yes—quick-cooking oats will work, but they absorb liquid faster and break down more during baking, so the cookies will be a bit softer and less chewy. If you substitute them 1:1, watch the bake time (they may set a minute sooner), or hold back a tablespoon or two of the oats to prevent the dough from becoming overly thick.
What’s the best way to freeze the cookie dough so I can bake fresh cookies later?
Scoop the finished dough into tablespoon-sized mounds on a parchment-lined sheet pan, flatten slightly, and freeze until solid (about 1–2 hours). Transfer the frozen portions to a zip-top freezer bag or airtight container, label with date and bake temp/time, and keep frozen up to 3 months. Bake straight from frozen at 350 °F, adding 1–2 extra minutes to the original baking time.
How can I adapt this oatmeal cookie recipe for a gluten-free version?
Substitute the 1½ cups of all-purpose flour with an equal amount of a cup-for-cup gluten-free baking blend that contains xanthan gum (or add ½ teaspoon xanthan gum if your blend is gum-free). Be sure to use certified gluten-free rolled oats—and keep all tools and work surfaces free of wheat flour—to prevent cross-contamination; the rest of the recipe and bake time remain unchanged.
