Chewy, bakery-style oatmeal chocolate chip cookies with crisp edges, warm cinnamon, and melty chocolate in every bite. Easy to make and perfect for sharing.
Preheat oven to 350°F. Line 2 baking sheets with parchment paper.
In a large bowl, beat softened butter, brown sugar, and granulated sugar until light and fluffy, about 2 minutes.
Beat in eggs one at a time, then mix in vanilla extract until smooth.
In a separate bowl, whisk together flour, baking soda, cinnamon, and salt.
Add dry ingredients to the wet ingredients and mix on low just until combined; do not overmix.
Stir in rolled oats, then fold in chocolate chips and nuts (if using).
Scoop dough into 1.5 tablespoon portions and place 2 inches apart on prepared sheets. For thicker cookies, chill scooped dough for 20 minutes (optional).
Bake 11 to 12 minutes, until edges are golden and centers look just set.
Cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
Store in an airtight container at room temperature for up to 5 days or freeze up to 2 months.
Notes
For chewier cookies, slightly underbake and let them finish setting on the hot baking sheet. Swap chocolate chips with raisins for a classic oatmeal raisin variation.
