Step 1

In a medium bowl, whisk flour, cinnamon, baking soda, and salt. Set aside.

Step 2

In the bowl of an electric mixer, beat butter and sugars on med-high until pale and fluffy (approx. 3 minutes).

Add eggs one at a time, fully incorporating after each addition, and beat on high for 1 minute. Add vanilla.

Step 4

Turn mixer to low and add flour mixture, mix until combined.

Step 5

Add oats and chocolate chips. Mix until just combined.

Step 6

Chill dough in the fridge for an hour (optional, but yields better results).

Step 7

Preheat oven to 350F and line a baking sheet with parchment or a Silpat.

Step 8

Using a small cookie scoop, place cookies on baking sheet 2" apart. I did 11 cookies per sheet.

Step 10

Cool for 5 minutes on baking sheet, then transfer to cooling rack to cool completely.
