Traditional oatmeal cookies are chewy, warmly spiced cookies made with rolled oats, butter, brown sugar, and a little vanilla. This straightforward American-style version has crisp edges and a tender center, with the option to add raisins for a familiar finish.
Ingredients
- 1 cup (227 g) unsalted butter, softened
- 1 cup packed (220 g) 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 cup and leveled
- 1 teaspoon (5 g) baking soda
- ½ teaspoon (3 g) fine salt
- 1 teaspoon (2 g) ground cinnamon
- 3 cups (270 g) old-fashioned rolled oats
- 1 cup (150 g) raisins, optional
Instructions
- Set a rack in the center of the oven and heat it 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 oily or melted.
- In a large bowl, beat the butter, brown sugar, and granulated sugar with a hand mixer on medium speed for about 2 minutes, until creamy and evenly combined. Scrape down the bowl once if needed. A sturdy spoon works too, though mixing will take a little longer.
- Beat in the eggs one at a time, mixing until each is incorporated, then mix in the vanilla. The mixture may look slightly curdled; it will come together when the dry ingredients are added.
- In a separate bowl, whisk together 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 prolonged mixing, which can make the cookies firm.
- Fold in the oats and, if using, the raisins. Stir only until they are distributed through the dough. Let the dough stand for 15 minutes so the oats can absorb some moisture; this helps the cookies hold their shape.
- Scoop rounded tablespoons of dough, about 1½ tablespoons (roughly 30 g) each, onto the prepared sheets. Leave about 2 inches (5 cm) between portions. For more uniform cookies, use a cookie scoop and keep the portions similar in size.
- 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 continue setting on the hot pan, so do not wait for the centers to look completely dry.
- Cool the cookies on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely. Repeat with the remaining dough, using a cool baking sheet. The recipe makes about 24 cookies, depending on scoop size.
Tips
- Measure flour by spooning it into the cup and leveling the top, rather than scooping directly from the bag. Too much flour can make the cookies dry and cakey.
- Use old-fashioned rolled oats for a distinct, pleasantly chewy texture. Quick oats absorb moisture differently and produce a softer, less textured cookie; steel-cut oats are too firm for this dough.
- If the dough spreads too much, check that the butter was softened rather than melted and that the baking sheet was cool. You can chill the scooped dough for 20 minutes if your kitchen is warm, though the cookies may need an extra minute to bake.
- For a dairy-free batch, use a firm plant-based baking stick in place of butter; avoid soft tub spreads, which contain more water and may cause excess spreading. The flavor and browning will differ slightly.
Serving Suggestions
Serve the cookies once they have cooled enough to hold their shape, or enjoy one slightly warm with a glass of milk, tea, or coffee. They also make an easy dessert alongside sliced apples or a scoop of vanilla ice cream. For a simple cookie sandwich, spread a thin layer of frosting or softened ice cream between two completely cooled cookies.
Variations
Raisins are optional, not essential: leave them out for a plain cinnamon-oat cookie, or replace them with 1 cup (170 g) of semisweet chocolate chips. Chopped walnuts or pecans add crunch; use ¾ cup (85 g) and fold them in with the oats. For a brighter flavor, add 1 teaspoon of finely grated orange zest. Keep the total add-ins close to 1 cup so the dough still holds together.
For a slightly deeper spice profile, increase the cinnamon to 1½ teaspoons and add ¼ teaspoon ground nutmeg. If using salted butter instead of unsalted, reduce the added salt to ¼ teaspoon. These are flexible flavor changes; avoid reducing the sugar substantially, since it affects both spread and texture.
Storage and Reheating
Cool baked cookies completely, then store them in an airtight container at room temperature for up to 5 days. Keep them away from direct sunlight and heat. If adding a piece of bread to the container to soften the cookies, replace it daily and discard it if it becomes stale or damp.
For longer storage, freeze cooled cookies in a freezer-safe airtight container, separated with parchment, for up to 3 months. Thaw at room temperature for about 30 minutes. To serve them warm, heat a cookie in a 300°F (150°C) oven for 3–4 minutes, or microwave one for about 8–10 seconds; avoid overheating, which can make it tough. Refrigeration is not necessary for these cookies, and the dough can be frozen in scoops for up to 3 months; bake from frozen at the same temperature, adding roughly 1–2 minutes.
Frequently Asked Questions
Can I use quick oats instead of rolled oats?
Yes, but expect a softer cookie with less oat texture. Old-fashioned rolled oats give the most traditional chewy bite. Do not substitute steel-cut oats, which will remain too hard.
Why did my oatmeal cookies spread too much?
Butter that is melted or overly warm is a common cause. Measuring too little flour, using a hot baking sheet, or placing dough too close together can also lead to thin cookies. Chill the next batch briefly and bake it on a cool, lined sheet.
Can I make the dough ahead?
Yes. Cover and refrigerate it for up to 24 hours, then let it sit at room temperature for 10–15 minutes if it is too firm to scoop. You can also freeze portioned dough for up to 3 months and bake it from frozen, allowing a little extra time.
How do I know when the cookies are done?
Look for lightly golden edges and centers that appear set around the outside but still soft in the middle. They firm up as they cool on the baking sheet. Baking until the entire surface looks dry usually produces a crisper cookie.
Can I make these without raisins?
Yes. Simply omit them; no other change is needed. You may leave the cookies plain or replace the raisins with chocolate chips or chopped nuts in a similar amount.
Can I make the cookies gluten-free?
Use a cup-for-cup gluten-free flour blend formulated for baking and certified gluten-free oats if gluten cross-contact is a concern. Texture can vary by blend, so check the cookies at the early end of the baking range and let them cool fully before moving them.
