Instructions
Preheat your oven to 350 degrees Fahrenheit. Line two sheet pans with parchment paper or silicone baking mats.
In the bowl of a stand mixer with the paddle attachment, beat the butter, sugar, and brown sugar until light and fluffy, about 3 minutes.
Add the vanilla, egg, and the egg yolk to the butter mixture and beat until combined. Scrape down the sides of the bowl with a spatula.
Add the oat flour, rolled oats, cinnamon, baking soda, and kosher salt to the butter mixture. Beat until incorporated and a cookie dough forms.
Use a small cookie scoop to scoop 8 cookies onto each prepared sheet pan. Give the cookies space to spread!
Place the sheet pans in the oven and bake for 11 minutes, or until the edges are golden brown but the centers look underdone.
Remove the cookies from the oven and let them cool on the pans for at least 5 minutes. Once they are set up and easy to transfer, move them to a wire rack to cool completely.
