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 light and fluffy. This should take about 2-3 minutes using an electric mixer.
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.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon. Gradually add the dry ingredients to the wet mixture, mixing just until combined.
Step 5: Fold in Oats and Add-Ins
Using a wooden spoon or spatula, fold in the rolled oats and raisins or chocolate chips (if using). Ensure the oats are evenly distributed throughout the dough.
Step 6: Shape and Bake
Scoop the dough into 2-tablespoon-sized balls and place them on the prepared baking sheets, spacing them about 2 inches apart. Flatten each ball slightly with the palm of your hand.
Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown and the centers look slightly underbaked. Do not overbake; this ensures the cookies stay chewy.
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: The key to chewy cookies is removing them from the oven while the centers are still soft.
- Chill the Dough: For thicker cookies, chill the dough for 30 minutes before baking.
- Customize Add-Ins: Swap raisins for dried cranberries, nuts, or white chocolate chips for variety.
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 these cookies?
Store in an airtight container at room temperature for up to a week. For longer storage, freeze the dough balls and bake fresh as needed.
Can I use quick oats instead of old-fashioned oats?
While you can use quick oats, the texture will be slightly different. Old-fashioned oats provide a chewier result.
