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
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.
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.
3. Add Eggs and Vanilla
Beat in the eggs one at a time, ensuring each is fully incorporated. Add the vanilla extract and mix until combined.
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.
5. Fold in Oats
Using a spatula, gently fold in the rolled oats and raisins or chocolate chips (if using) until evenly distributed.
6. Scoop and Bake
Drop rounded tablespoons 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.
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
- Room Temperature Butter: Ensure your butter is softened but not melted for the perfect cookie texture.
- 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 a unique twist.
- Even Baking: Rotate the baking sheets halfway through baking for evenly golden cookies.
FAQ
Can I use quick oats instead of old-fashioned oats?
Yes, but the texture will be slightly different. Quick oats yield a softer cookie, while old-fashioned oats provide a chewier texture.
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 make these cookies gluten-free?
Absolutely! Substitute the all-purpose flour with a gluten-free flour blend. Ensure your oats are certified gluten-free as well.
