When I challenged myself to make every single recipe in America's Test Kitchen's Best-Ever Christmas Cookies (not in one day, of course), these cookies jumped out to me quite quickly. The ingredients were simple enough, and I wanted to buy some flaky sea salt anyway. Even though the title might suggest something healthier than the typical cookies, let me warn you that in just 24 cookies, I used 2 sticks of butter and 2 full cups of sugar. Yes, you read that right.
So with that, the cookies came out just as well. The buttery and sweet taste, along with the semi-crunch from the oats, these cookies were fun and different to eat. The flaky sea salt definitely took the top spot, and catapulted the entire thing. It created such a fun and nice contrast to the buttery and sweet taste that made these cookies so much fun to eat.
On a side note, the magazine said that you can substitute kosher salt for the flaky salt, just lesson the amount that is sprinkled onto the cookies. However, don't substitute the rolled oats for quick or instant oats.
