Preparation
Step 1
Using a hand mixer or a stand mixer fitted with paddle attachment, cream the softened butter and both sugars together on medium speed until smooth, about 2 minutes. Add the eggs and mix on high until combined, about 1 minute. Scrape down the sides and bottom of the bowl as needed. Add the vanilla and molasses and mix on high until combined. Set aside.
Step 2
In a separate bowl, whisk the flour, baking soda, cinnamon, and salt together. Add to the wet ingredients and mix on low until combined. Beat in the oats and chocolate on low speed. Dough will be thick, yet very sticky. Chill the dough for 30-60 minutes in the refrigerator (I always chill this dough for only 30 minutes). If chilling for longer (up to 2 days), allow to sit at room temperature for at least 30 minutes before rolling and baking. The cookies won’t spread as much if chilled for longer than 1 hour.
Step 3
Preheat oven to 350°F (177°C). Line two large baking sheets with parchment paper or silicone baking mats. Set aside.
Step 4
Roll balls of dough (about 1 and 1/2 Tablespoons of dough per cookie) and place 2 inches apart on the baking sheets. I recommend using a cookie scoop since the dough can be sticky. Bake for 11-12 minutes or until lightly browned on the sides. The centers will look soft and under-baked. Remove from the oven, immediately sprinkle each with sea salt (if using), then let cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely. The cookies will continue to “set” on the baking sheet during this time.
Step 5
Cover and store leftover cookies at room temperature for up to 1 week.
Step 6

Chef's notes
Make Ahead & Freezing Instructions:
Baked cookies freeze well up to three months. Unbaked cookie dough balls freeze well—up to three months. Bake frozen cookie dough balls for an extra minute, no need to thaw.
Special Tools (affiliate links):
Electric Mixer (Handheld or Stand) | Baking Sheet | Silicone Baking Mat or Parchment Paper | Medium Cookie Scoop | Cooling Rack
Molasses:
If you don’t have molasses, you can leave it out. It’s used to add a little extra flavor, and won’t affect the texture if you skip it. You could also replace it with pure maple syrup.
Oats:
For these oatmeal cookies, I use and recommend old-fashioned whole oats. They provide the ultimate hearty, chewy, thick texture we love!
Eggs:
Room temperature eggs preferred. Good rule of thumb
Chocolate:
Though chocolate chips work just fine, if you want big chunks of melty chocolate, use pure baking chocolate. See Best Chocolate to Use in the blog post above. I prefer semi-sweet or bittersweet chocolate here. Chop chocolate into chunks around the same size or slightly larger than chocolate chips.
