These easy oatmeal cookies use quick oats, butter, brown sugar, and a touch of cinnamon for soft centers and lightly crisp edges. The oats make a tender, chewy cookie without needing a mixer, and the dough comes together with everyday pantry ingredients.
Ingredients
- 1 cup (226 g) unsalted butter, softened but not melted
- 1 cup (200 g) packed light brown sugar
- ½ cup (100 g) granulated sugar
- 2 large eggs (about 100 g without shells), at room temperature
- 2 teaspoons (10 ml) vanilla extract
- 1½ cups (188 g) all-purpose flour, spooned into the measuring cup and leveled
- ½ teaspoon baking soda (about 2.5 g)
- ½ teaspoon fine salt (about 3 g)
- ½ teaspoon ground cinnamon (about 1.3 g)
- 3 cups (240 g) quick oats
- ½ cup (75 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 gentle press but still feels cool; butter that is melted or greasy can make the cookies spread too much.
- In a large bowl, beat the softened butter with the brown sugar and granulated sugar until creamy and evenly combined, about 2 minutes by hand with a sturdy spoon or 1–2 minutes with a hand mixer. Scrape down the bowl so no thick patches of butter remain.
- Beat in the eggs one at a time, mixing until each is incorporated. Stir in the vanilla. If the mixture looks slightly curdled, continue with the recipe; 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 just until no dry flour is visible. Fold in the quick oats and, if using, raisins or chocolate chips. Avoid prolonged mixing, which can make the cookies firm.
- Scoop level portions of dough, about 1½ tablespoons (roughly 30 g) each, onto the prepared sheets, leaving about 2 inches (5 cm) between them. For more evenly shaped cookies, roll each portion lightly between your palms. The dough should be thick and scoopable; if your kitchen is warm and it feels greasy, chill it for 15 minutes before baking.
- Bake one sheet at a time for 10–12 minutes, until the edges are lightly golden and set while the centers still look soft. Rotate the sheet once if your oven browns unevenly. The cookies will finish setting as they cool, so avoid waiting for the centers to turn deeply brown.
- 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. For consistent results, let a hot baking sheet cool before putting another batch on it.
Tips
- Measure flour carefully. Spoon it into the cup and level the top rather than packing flour into the cup. Too much flour can make oatmeal cookies dry and thick.
- Use softened, not melted, butter. If the butter is too soft, briefly chill the dough before scooping. If it is too cold, it will not cream smoothly with the sugar.
- Keep the oats quick. Quick oats are thinner and smaller than old-fashioned rolled oats, so they blend into the dough and give a more uniform, tender texture. Rolled oats work in a pinch, but the cookies will be chewier and more textured.
- Check early. Ovens and cookie-scoop sizes vary. Begin checking at 10 minutes; pale centers are fine as long as the edges are set. For food safety, the USDA FSIS safe minimum temperature for egg dishes is 160°F (71°C); the cookies’ centers should reach that temperature, which can be checked with a suitable food thermometer if needed.
Serving Suggestions
Serve the cookies warm or at room temperature with a glass of milk, coffee, or tea. They are also good alongside fresh fruit, or crumbled over a bowl of vanilla ice cream. If serving warm cookies with ice cream, let them cool for a few minutes first so they stay pleasantly chewy rather than falling apart.
Variations
For a classic raisin version, use the optional raisins; plump, soft raisins work best. Chocolate chips make a sweeter cookie, while chopped walnuts or pecans add crunch—replace some or all of the raisins with up to ½ cup (60 g) nuts. You can also add ½ teaspoon (about 1 g) ground nutmeg alongside the cinnamon for a warmer spice flavor.
To make the recipe without raisins or chocolate, simply leave them out; no other adjustment is needed. For a dairy-free version, use a firm dairy-free baking stick in place of the butter rather than a soft tub spread, which may cause excess spreading. A gluten-free all-purpose flour blend labeled as a 1:1 baking substitute can replace the flour, but check that the oats are certified gluten-free if avoiding gluten is necessary; texture can vary by blend.
Storage and Reheating
Cool the cookies completely, then store them in an airtight container at room temperature for up to 4 days. Refrigeration is not needed for plain cookies and can make them firm. For food safety, refrigerate cooked foods within 2 hours; if the cookies are kept in a hot environment above 90°F (32°C), do not leave them out for more than 1 hour.
To freeze baked cookies, place them in a freezer-safe airtight container with parchment between layers and freeze for up to 3 months. Thaw at room temperature for about 30–45 minutes. To warm a cookie, microwave it for 8–12 seconds, or heat it in a 300°F (150°C) oven for about 4–5 minutes. Avoid overheating, which can dry it out. 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.
Frequently Asked Questions
Can I use old-fashioned oats instead of quick oats?
Yes. Use the same quantity by volume, 3 cups (240 g), but expect a more pronounced oat texture and chewier cookies. Do not use instant oatmeal packets, which may contain added sugar, salt, or flavorings.
Do I need to chill the dough?
Not usually. The dough can be baked as soon as it is mixed. Chill it for 15–30 minutes if it is very soft, your kitchen is warm, or you prefer slightly thicker cookies; allow the oven to stay at the specified temperature.
Why did my oatmeal cookies spread too much?
Common causes include melted butter, warm dough, a hot baking sheet, or too little flour. Use softened butter, measure flour by spooning and leveling, and bake on a cool sheet. Chilling the scooped dough for 15 minutes can also help.
How do I keep the cookies soft?
Take them out when the edges are set and lightly golden but the centers still look a little soft. Let them rest on the sheet for 5 minutes, then store fully cooled cookies in an airtight container. Overbaking is the most common cause of dry cookies.
Can I make the dough ahead?
Yes. Cover the bowl and refrigerate the dough for up to 24 hours, then scoop and bake. Chilled dough may need an extra minute or two in the oven. For longer storage, freeze individual portions and bake from frozen as directed above.
Can I reduce the sugar?
You can reduce either sugar by about 2 tablespoons (25 g), but the cookies may spread less and have a less tender texture. Sugar affects structure as well as sweetness, so a large reduction can make the finished cookies dry or crumbly.
