Ingredients for Perfect Oatmeal Cookies

- 1 cup (226 g) unsalted butter, softened (room temperature works best)
- 1 cup (200 g) light brown sugar, firmly packed
- ½ cup (100 g) granulated sugar
- 2 large eggs, room temperature preferred
- 1 ½ teaspoons vanilla extract
- 1 ¾ cups (215 g) all-purpose flour
- 2 teaspoons cornstarch (cornflour in the UK)
- 1 teaspoon baking soda
- ¾ teaspoon table salt
- ¾ teaspoon ground cinnamon
- 3 cups (285 g) old-fashioned rolled oats
- 1 ½ cups chocolate chips, chopped nuts, or raisins (optional, but delicious!)
Step-by-Step Instructions
- Beat the butter: In a stand mixer or with an electric beater, beat the softened butter for about 30 seconds until smooth.
- Add sugars: Add the light brown sugar and granulated sugar, then beat until light and fluffy. Scrape down the sides and bottom of the bowl as needed.
- Incorporate eggs: Add the eggs one at a time, beating until fully combined after each addition.
- Mix in vanilla: Stir in the vanilla extract until evenly distributed.
- Combine dry ingredients: In a separate bowl, whisk together the flour, cornstarch, baking soda, salt, and cinnamon.
- Add dry mixture: Gradually add the dry ingredients to the butter mixture, mixing until completely combined. Scrape the bowl to ensure even mixing.
- Fold in oats: Gradually stir in the rolled oats until fully incorporated. If using chocolate chips, nuts, or raisins, add them now.
- Chill the dough: Cover the dough with plastic wrap and refrigerate for at least 30 minutes (or up to 3 days).
- Preheat oven: Preheat your oven to 375°F (190°C) and line cookie sheets with parchment paper.
- Shape cookies: Drop the dough by rounded 2-tablespoon portions onto the prepared sheets, spacing them at least 2 inches apart. For uniform cookies, roll the dough into smooth balls.
- Bake: Bake for 10-12 minutes, or until the edges are lightly browned. The centers may look slightly underbaked but will set as they cool.
- Cool and enjoy: Let the cookies cool completely on the baking sheet before serving.
Creative Add-Ins for Your Oatmeal Cookies
While chocolate chips, nuts, and raisins are classic choices, don’t hesitate to get creative! Try adding dried cranberries for a tart twist, shredded coconut for a tropical vibe, or white chocolate chips for a sweeter flavor. For a crunchy texture, mix in toasted pecans or walnuts. The possibilities are endless—experiment to find your perfect combination!
How to Store and Keep Cookies Fresh
Once cooled, store your oatmeal cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze the dough balls on a baking sheet, then transfer them to a freezer-safe bag for up to 3 months. When ready to bake, simply pop them in the oven—no need to thaw! Baked cookies can also be frozen for up to 2 months.
Time-Saving Tips for Busy Bakers
Short on time? Skip the chilling step if you’re in a hurry—your cookies will spread a bit more but will still taste delicious. Alternatively, prepare the dough ahead of time and refrigerate it for up to 3 days. You can also use a cookie scoop to portion the dough quickly and evenly, saving you time and effort.
Perfect Pairings for Your Cookies
These oatmeal cookies pair wonderfully with a glass of cold milk or a cup of hot coffee or tea. For a special treat, serve them alongside a scoop of vanilla ice cream or drizzle them with caramel sauce. They’re also a great addition to a dessert platter with fresh fruit or other baked goods.
Common Questions Answered
Can I use quick oats instead of old-fashioned rolled oats? Yes, but the texture will be slightly softer. Can I make these cookies gluten-free? Absolutely! Substitute the all-purpose flour with a gluten-free blend. Why chill the dough? Chilling helps prevent the cookies from spreading too much and enhances the flavors. Happy baking!
