CHEWY OATMEAL COOKIES

Steps:

• Preheat the oven to 350 degrees F (175 degrees C), with racks in the upper and lower thirds. Line two baking sheets with parchment paper.
• In the bowl of a stand mixer fitted with the paddle attachment (or in a large bowl, using a hand mixer), cream the butter and sugars on medium-low speed until light and fluffy, 4 to 5 minutes.
• Add the eggs one at a time, mixing on medium speed until each one is fully incorporated. Add the vanilla and mix to combine. Scrape the bowl well.
• In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon. Add to the butter mixture and mix on low speed just until incorporated, 1 to 2 minutes. Add the oats and mix on low speed to combine, 30 seconds to 1 minute. Scrape the bowl well.
• Use a No. 16 (1/4-cup) scoop to portion the cookie dough onto the prepared baking sheets --stagger the cookies, leaving 1 1/2 inches between them to allow for spreading.
• Bake the cookies, rotating the sheets from front to back and top to bottom at the halfway mark, until evenly golden brown, 14 to 16 minutes. Transfer the cookies to wire racks to cool.
