Oatmeal Cookies Using Old-Fashioned Oats

Oatmeal cookies using old-fashioned oats are chewy-centered, lightly crisp-edged cookies made with rolled oats, butter, brown sugar, and warm cinnamon. The large flakes give them a satisfying texture and help the dough hold its shape; enjoy them plain or add raisins or chocolate chips.

Ingredients

1 cup (227 g) unsalted butter, softened
1 cup (220 g) packed light brown sugar
½ cup (100 g) granulated sugar
2 large eggs (about 100 g without shells), at room temperature
1 teaspoon (5 ml) vanilla extract
1½ cups (190 g) all-purpose flour, spooned into the measuring cup and leveled
1 teaspoon (5 g) baking soda
1 teaspoon (2 g) ground cinnamon
½ teaspoon (3 g) fine salt
3 cups (270 g) old-fashioned rolled oats
¾ cup (110 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 still feels cool; melted butter can make the cookies spread too much.
In a large bowl, beat the butter, brown sugar, and granulated sugar for about 2 minutes, until creamy and evenly combined. A hand mixer or stand mixer makes this easiest, but a sturdy spoon and a little elbow grease also work.
Beat in the eggs one at a time, scraping down the bowl as needed, then mix in the vanilla. The mixture may look slightly curdled after the eggs go in; it will come together when the dry ingredients are added.
In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt. Add this mixture to the butter mixture and stir just until no dry flour remains. Fold in the old-fashioned oats and, if using, the raisins or chocolate chips. Avoid prolonged mixing, which can make the cookies firm.
Scoop rounded tablespoons of dough, about 1½ tablespoons (30 g) each, onto the prepared sheets, leaving roughly 2 inches (5 cm) between portions. For more evenly shaped cookies, gently roll each portion into a ball; do not flatten it.
Bake one sheet at a time for 10–12 minutes, until the edges are lightly golden and the centers still look a little soft. Rotate the sheet once if your oven browns unevenly. The cookies firm as they cool, so avoid waiting for the centers to look completely dry in the oven.
Leave the cookies on the baking sheet for 5 minutes, then transfer them to a wire rack to cool. Bake the remaining dough in batches, using a cool baking sheet so the dough does not start melting before it reaches the oven. The recipe makes about 24 cookies.

Tips

Measure flour lightly. Spoon it into the cup and level the top rather than scooping directly from the bag. Too much flour can make the cookies dry and cakey.
Use old-fashioned oats for texture. Quick oats are more finely cut and absorb moisture differently, so cookies made with them will be less distinct and can turn softer or denser. Steel-cut oats are not a suitable direct substitute.
Keep the dough consistent. A tablespoon measure or small cookie scoop helps the portions bake evenly. If the kitchen is warm and the dough feels greasy or very soft, chill it for 20 minutes before scooping.
Check early. Ovens and sheet materials vary. Start checking at 10 minutes; remove the cookies when the edges are set and the centers remain tender rather than waiting for deep browning.

Serving Suggestions

Serve the cookies slightly warm or fully cooled with a glass of milk, coffee, or tea. For a simple dessert, sandwich a small scoop of vanilla ice cream between two cooled cookies, or crumble one over yogurt or a bowl of fruit just before serving. If serving them warm from the oven, allow enough time for the centers to set so they do not break apart when lifted.

Variations

Raisin and spice: Use raisins and increase the cinnamon to 1½ teaspoons (3 g); a pinch of nutmeg is also a good fit. Chocolate chip: Use semisweet or dark chocolate chips instead of raisins, or combine half of each. Nutty: Replace up to ½ cup (55 g) of the oats with chopped walnuts or pecans. Less sweet: Reduce the granulated sugar to ⅓ cup (67 g); the cookies will be a little less sweet and may spread slightly differently. For a dairy-free batch, use a firm baking stick made for baking rather than a soft tub spread, which can lead to excess spreading.

Storage and Reheating

Cool the cookies completely before storing them in an airtight container at room temperature for up to 5 days. For food safety, refrigerate perishable foods within 2 hours; these plain cookies are shelf-stable, but any serving that includes a perishable filling or topping should be refrigerated promptly. To freeze baked cookies, pack them airtight for up to 3 months and thaw at room temperature. You can also freeze scooped, unbaked dough portions for up to 2 months; bake from frozen at 350°F (175°C), adding about 1–3 minutes and checking for set edges. To warm a baked cookie, microwave it for about 8–10 seconds; longer heating can make it tough.

Frequently Asked Questions

Can I make the dough ahead?
Yes. Cover and refrigerate the dough for up to 24 hours. Chilled dough is firmer and may spread less, so let it stand for about 10 minutes if it is too hard to scoop. The required chilling time is additional to the recipe’s listed preparation time.

Can I use quick oats instead of old-fashioned oats?
You can, but the texture will change. Quick oats are smaller and make a more compact, less chewy cookie. Use the same volume as a practical swap, and check the first batch early because the finished texture may differ.

Why did my oatmeal cookies spread too much?
Common causes are butter that was melted or too warm, a warm baking sheet, or flour that was undermeasured. Chill soft dough for 20 minutes and bake each batch on a cool sheet. Check that your baking soda is fresh, too.

Why are the cookies dry or hard?
Too much flour, overmixing after adding flour, or baking until the centers are completely firm can all make cookies dry. Measure flour by spooning and leveling, mix only until combined, and take the cookies out when their centers still look soft.

Do I need to chill the dough?
No; the dough can be baked right after mixing. Chilling is useful if the dough feels very soft or if you want to prepare it ahead, but it may reduce spreading, so the cookies can come out thicker.

How can I tell when they are done?
Look for lightly golden, set edges and centers that still appear slightly underbaked. Let the cookies rest on the hot baking sheet for 5 minutes; carryover heat finishes setting them without drying them out.
