Nutty cinnamon sugar cookies (Print Version)

# Ingredients:

01 - 12 Tbsp unsalted butter, softened to room temperature and divided
02 - 1¼ cups granulated white sugar
03 - 1/2 cup light brown sugar, lightly packed
04 - 1 large egg
05 - 1 large egg yolk
06 - 1 Tbsp pure vanilla extract
07 - 1 tsp baking soda
08 - 2 tsp cream of tarter
09 - 1/2 tsp salt
10 - 2 cups all-purpose flour
11 - 1/4 cup granulated white sugar
12 - 3 tsp ground cinnamon

# Instructions:

01 - Preheat the oven to 350℉.
02 - In a small saucepan, add in 8 Tbsp (1 stick) unsalted butter over medium-low heat and allow the butter to melt. Once melted, the butter will bubble and sizzle. After about 5 minutes, it may become foamy. Swirl the pan occasionally. Remove from heat when the butter is amber in color and smells nutty.
03 - Pour the brown butter into the bowl of a stand mixer with the remaining 4 Tbsp softened butter. Allow to sit for 5 minutes. Then, add in the sugars and beat with the paddle attachment until combined, about 1 minute. Add in the egg, followed by the egg yolk, mixing well, followed by the vanilla.
04 - Add in your baking soda, cream of tarter, salt, and flour and mix until just combined; set aside. Meanwhile, in a small bowl, mix together the remaining granulated sugar and cinnamon.
05 - Line two baking sheets with parchment paper. Using a Tablespoon-size cookie dough scoop, portion out dough balls one at a time. Drop a rounded dough ball into the cinnamon sugar mixture and toss gently to coat. Place the dough balls 2" apart on the baking sheets.
06 - Bake for 10-12 minutes, rotating the pans halfway through baking time to ensure even baking. Remove from the oven and allow to cool on the baking sheets for 5 minutes before carefully transferring to a wire rack to cool completely.
07 - If you have any leftover cinnamon sugar, sprinkle it over the still-warm cookies.

# Notes:

01 - Cookies may appear puffy and deflate; this is normal as they are a crisper cookie than a traditional puffy one.
02 - These cookies have a deliciously nutty flavor from the brown butter.
