Step-by-Step Instructions
Step 1: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
Step 2: In a large mixing bowl, combine the softened butter, brown sugar, and granulated sugar. Use a wooden spoon or spatula to mix until well combined and creamy.
Step 3: Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Step 4: Add the flour, baking soda, salt, and cinnamon directly into the same bowl. Mix until just combined – don’t overmix.
Step 5: Fold in the oats and any optional add-ins like raisins or chocolate chips until evenly distributed.

Expert Tips
For the chewiest cookies, slightly underbake them – they’ll continue to set as they cool on the baking sheet. If you love variety, try adding different mix-ins like dried cranberries, chopped nuts, or white chocolate chips. These cookies freeze beautifully – just place cooled cookies in an airtight container with parchment between layers.

FAQ
Can I make these cookies gluten-free?
Yes! Simply substitute the all-purpose flour with your favorite gluten-free flour blend.
How long do these cookies stay fresh?
Store in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months.
Can I use quick oats instead of old-fashioned?
Yes, but the texture will be slightly different. Quick oats will make a denser, less chewy cookie.
