This is the cookie for cinnamon-lovers! This delicious recipe is a mashup between a cinnamon roll, a snickerdoodle, and a sugar cookie. Soft and chewy sugar cookies with an incredible brown sugar-cinnamon swirl marbled all throughout.
Preheat oven to 350°F with racks near the center. Line two baking sheets with parchment paper and set aside.
Mix together all ingredients (I use a small rubber spatula or fork) until well combined. Place in the freezer for about 10 minutes while you prepare the cookie dough.
Using an hand mixer, or stand mixer fitted with the paddle attachment, beat butter and sugar until light and creamy. Add vanilla, egg, and egg yolk, and beat until combined, scraping the sides of the bowl as necessary.
