Preparation

• In a medium bowl, whisk the flour, cinnamon, baking soda, and salt together. Set aside.
• In a large bowl using a hand mixer or a stand mixer fitted with a paddle attachment, beat the butter, brown sugar, and granulated sugar together on medium-high speed until combined and creamed, about 3 minutes.
• Add the eggs, molasses, and vanilla and beat on high speed until combined, about 1 minute. Scrape down the sides and bottom of the bowl and beat again as needed to combine.
• Add the dry ingredients to the wet ingredients and mix on low speed until combined. Beat in the oats and chocolate chips. Dough will be thick and sticky.
• Cover and refrigerate the dough for at least 45 minutes in the refrigerator (and up to 4 days).
• Preheat oven to 350°F (177°C). Line baking sheets with parchment paper or silicone baking mats. Set aside.
• Use a medium cookie scoop to scoop the cookie dough, about 2 Tablespoons (40g) of dough per cookie, and place 3 inches apart on the baking sheets.
• Bake for 13–14 minutes or until lightly browned on the sides. The centers will look very soft.
• Remove from the oven and allow cookies to cool on the baking sheet for 5 minutes before transferring to a cooling rack to cool completely.
• While the cookies are still warm, press a few more chocolate chips into the tops and sprinkle with flaky sea salt—both are optional!
