Ingredients

- 1 cup (2 sticks) unsalted butter, softened
- 1 cup packed brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 3 cups old-fashioned rolled oats
- 1 cup raisins or chocolate chips (optional)
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats to prevent sticking.
Step 2: Cream Butter and Sugars
In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy. This step is crucial for creating a chewy texture.
Step 3: Add Eggs and Vanilla
Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract for a warm, aromatic flavor.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon. Gradually add this dry mixture to the wet ingredients, mixing just until combined.
Step 5: Fold in Oats and Add-Ins
Gently fold in the rolled oats and any optional add-ins like raisins or chocolate chips. The oats give these cookies their signature chewy texture.
Step 6: Scoop and Bake
Using a cookie scoop or tablespoon, drop rounded portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown and the centers look slightly underbaked. This ensures a soft and chewy result.
Step 7: Cool and Enjoy
Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. Enjoy warm or store in an airtight container for up to a week.
Expert Tips
- Use Room Temperature Butter: Softened butter creams more easily with the sugars, creating a lighter texture.
- Don’t Overbake: Pull the cookies out of the oven when the edges are set but the centers still look soft. They’ll continue to firm up as they cool.
- Customize Your Cookies: Swap raisins for dried cranberries, chopped nuts, or white chocolate chips for a unique twist.
- Chill the Dough: For thicker cookies, refrigerate the dough for 30 minutes before baking.
FAQ
Can I make these cookies gluten-free?
Yes! Substitute the all-purpose flour with a gluten-free flour blend. Ensure your oats are certified gluten-free as well.
How do I store chewy oatmeal cookies?
Store cookies in an airtight container at room temperature for up to a week. For longer storage, freeze them in a sealed bag for up to 3 months.
Can I use quick oats instead of old-fashioned oats?
While quick oats can be used, they may result in a slightly less chewy texture. Old-fashioned oats are recommended for the best results.
