Made with buttery oats, rich brown sugar, and warm cinnamon, these Soft and Chewy Oatmeal Cookies are the ultimate chewy cookies with incredible flavor that stays fresh for days.
Preheat the oven to 325 degrees Fahrenheit (163 degrees Celsius). Line 2–3 baking sheets with parchment paper, silicone baking mats, or spray with cooking spray.
In a large bowl or the bowl of a stand mixer, beat together the butter, brown sugar, and sugar until creamy. Add the eggs and vanilla and mix until smooth.
In a small bowl, whisk together the flour, baking soda, cinnamon, and salt. Add the dry ingredients to the wet ingredients and mix until almost combined. Add the oats and walnuts and mix by hand until combined.
Scoop the cookie dough in one-inch balls onto the prepared baking sheets. Bake for 12–14 minutes, until lightly browned on the bottoms. Let cool on a wire rack.
Notes
STORE Soft and Chewy Oatmeal Cookies in an airtight container at room temperature for up to 5 days, adding a slice of bread to help keep them soft.For longer storage, FREEZE baked cookies in a freezer-safe bag with parchment paper between layers for up to 3 months. To freeze cookie dough, scoop it into balls, flash freeze on a parchment-lined baking sheet, then transfer to an airtight container or freezer bag for up to 3 months. Bake frozen dough without thawing, adding an extra minute or two to the baking time. To REHEAT, microwave cookies for 8–10 seconds to restore their soft, chewy texture.
