Make bakery-style oatmeal cookies with chewy centers and crisp edges right at home. This easy recipe uses simple pantry ingredients like oats, brown sugar, butter, and vanilla for a classic flavor that never goes out of style. Customize your cookies with mix-ins such as raisins, chocolate chips, or nuts for the perfect homemade treat. These soft oatmeal cookies are great for snacking, lunch boxes, or holiday baking, and the dough can be chilled or frozen for make-ahead convenience.

Ingredients

1 ½ cups old-fashioned oats
¾ cup all-purpose flour
1 teaspoon ground cinnamon
¾ teaspoon fine sea salt*
½ teaspoon baking soda
½ cup unsalted butter, room temperature
⅔ cup packed light brown sugar
1 large egg
1 teaspoon vanilla extract
(Optional) Up to 1 cup mix-ins: raisins, chocolate chips, chopped nuts, M&Ms, dried fruit, or other baking chips

*You can adjust the salt slightly depending on your preference.

Instructions

1. Combine the dry ingredients

In a medium bowl, whisk together oats, flour, cinnamon, salt, and baking soda until well combined.

2. Cream the butter and sugar

In a large mixing bowl, using a stand mixer or hand mixer, beat the softened butter and brown sugar on medium-high speed until light and fluffy, about 2 minutes. Scrape down the sides of the bowl as needed.

3. Add egg and vanilla

Mix in the egg and vanilla extract, beating until just combined, about 30 seconds.

4. Mix in dry ingredients

Gradually add the dry mixture to the wet mixture, mixing on low speed until combined.

5. Stir in add-ins

Fold in any optional mix-ins by hand until evenly distributed.

6. Chill the dough

Cover and refrigerate the dough for 1–2 hours until firm. (For quicker chilling, you can spread the dough on a baking sheet and place it in the freezer for 20–30 minutes.)

7. Shape the cookies

Preheat the oven to 350°F (180°C) and line a baking sheet with parchment paper. Use a medium cookie scoop to portion the dough into 2-tablespoon balls, spacing them a few inches apart.

8. Bake

Bake for 10–12 minutes, or until the edges are lightly golden and the centers look set.

9. Cool and serve

Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack. Sprinkle with flaky sea salt if desired. Serve warm or store for later.

Tips

For chewier cookies, do not overbake. They will continue to set as they cool.
Chilling the dough prevents spreading and enhances flavor.
Use room temperature butter and egg for best results.
For thicker cookies, scoop taller mounds of dough instead of flattening.

FAQs
