National Oatmeal Cookie Day: Chewy Oatmeal Cookies

Celebrate National Oatmeal Cookie Day with chewy, buttery cookies made with rolled oats, brown sugar, and a touch of cinnamon. This straightforward drop-cookie recipe bakes up tender in the middle with lightly crisp edges, and it’s easy to customize with raisins or chocolate chips.

Ingredients

1 cup (226 g) unsalted butter, softened
1 cup (220 g) packed light brown sugar
½ cup (100 g) granulated sugar
2 large eggs, at room temperature
2 teaspoons vanilla extract (10 ml)
1½ cups (190 g) all-purpose flour, spooned into the measuring cup and leveled
1 teaspoon baking soda (5 g)
½ teaspoon fine salt (3 g)
1 teaspoon ground cinnamon (2.5 g)
3 cups (270 g) old-fashioned rolled oats
1 cup (150 g) raisins or chocolate chips (optional)

Instructions

Heat the oven to 350°F (175°C). Line two baking sheets with parchment paper. Let the butter soften until it yields to a light press but is not melted; this helps it cream evenly.
In a large bowl, beat the butter, brown sugar, and granulated sugar with a hand mixer on medium speed for 2–3 minutes, scraping the bowl once, until creamy and slightly fluffy. You can use a sturdy spoon and some elbow grease if you don’t have a mixer.
Beat in the eggs one at a time, mixing until each is incorporated. Add the vanilla and mix briefly. If the mixture looks a little curdled, continue; it will come together when the dry ingredients are added.
In a separate bowl, whisk the flour, baking soda, salt, and cinnamon. Add this mixture to the butter mixture and stir on low speed or by hand just until no dry streaks remain. Avoid overmixing, which can make the cookies firm.
Stir in the oats and, if using, raisins or chocolate chips. The dough should be thick and scoopable. For more evenly shaped cookies, use a tablespoon measure or a 1½-tablespoon cookie scoop.
Drop rounded portions of dough onto the lined sheets, leaving about 2 inches (5 cm) between them. Bake one sheet at a time for 10–12 minutes, until the edges are golden and the centers look set but still soft. Rotate the pan once if your oven browns unevenly.
Leave the cookies on the baking sheet for 5 minutes to firm, then transfer them to a wire rack to cool. Bake remaining dough in batches, using a cool baking sheet. The cookies continue to set as they cool, so don’t wait for the centers to look completely dry in the oven.

Tips

Measure flour lightly. Spoon it into the cup and level the top rather than packing it down. Too much flour can make oatmeal cookies dry and cakey.
Use old-fashioned rolled oats. They provide the familiar chewy texture. Quick oats absorb moisture differently and can make the cookies softer and less distinct; steel-cut oats are too tough for this recipe.
Control the spread. If the butter has become greasy or the dough feels very soft, chill it for 20–30 minutes before scooping. Don’t melt the butter as a shortcut.
Check early. Ovens and cookie sizes vary, so look at the first batch at 10 minutes. Pull the cookies when the edges are golden; baking until the centers are fully browned can leave them hard once cooled.

Serving Suggestions

Serve the cookies warm or at room temperature with a glass of milk, coffee, or tea. For a simple dessert, pair one with vanilla ice cream or crumble it over yogurt or pudding just before serving. If offering them as part of a cookie platter, let them cool fully so they hold their shape and don’t soften neighboring cookies.

Variations

For classic raisin oatmeal cookies, use the optional cup of raisins; plump, soft raisins blend particularly well into the chewy dough. For a chocolate version, use semisweet or dark chocolate chips instead, or combine half raisins and half chips while keeping the total add-ins to about 1 cup (150 g).

Chopped walnuts or pecans add crunch; substitute up to ¾ cup (90 g) of nuts for some of the raisins or chips. For a warmer spice profile, add ¼ teaspoon (0.5 g) ground nutmeg with the cinnamon. You can also replace the vanilla with an equal amount of maple extract, though the flavor will be more pronounced and less classic. Keep the flour, oats, and leavening amounts unchanged for the most dependable texture.

Storage and Reheating

Cool the cookies completely, then store them in an airtight container at room temperature for up to 5 days. To keep them soft, add a small piece of plain bread to the container and replace it when dry; don’t let the bread touch any toppings that could become damp. Refrigeration is unnecessary and may make cookies firm.

For longer storage, freeze cooled cookies in a freezer-safe airtight container, with parchment between layers, for up to 3 months. Thaw at room temperature. To warm a cookie, microwave it for about 8–12 seconds, checking before adding more time, or heat it in a 300°F (150°C) oven for 4–5 minutes. You can also freeze scoops of unbaked dough for up to 3 months; bake from frozen at 350°F (175°C), adding about 1–3 minutes and checking for golden edges.

Frequently Asked Questions

Why did my oatmeal cookies turn out dry?
Common causes include too much flour, overbaking, or measuring oats by packing them tightly into a cup. Spoon and level the flour, weigh the oats if possible, and remove cookies when the edges are golden and the centers are just set.

Can I make the dough ahead?
Yes. Cover and refrigerate it for up to 24 hours, then let it sit at room temperature for about 10–15 minutes if it is too firm to scoop. Chilled dough may need an extra minute or two in the oven; judge by the edges and centers rather than the clock alone.

Can I use quick oats instead of rolled oats?
You can, but the texture will be softer and less chewy, and the cookies may spread differently. For the result this recipe is designed for, choose old-fashioned rolled oats and don’t substitute steel-cut oats.

How do I know when the cookies are done?
The edges should look set and lightly golden, while the centers remain a little soft. They will continue to firm on the hot baking sheet for 5 minutes, so avoid waiting until the whole surface is browned.

Can I make these without raisins or chocolate?
Yes. Leave out the optional add-ins for a simple cinnamon-oat cookie. The dough may make slightly smaller cookies overall, but the baking method and timing remain the same.

Can I make the cookies gluten-free?
Use a cup-for-cup gluten-free flour blend that includes a binder, and choose oats labeled gluten-free if avoiding gluten due to cross-contact concerns. Results can vary by blend, so bake a small test batch first and check for doneness at the early end of the timing range.
