Preheat the oven to 350 degrees
Sift together flour, cream of tarter, baking soda, and salt; set aside.
In a stand mixer with paddle attachment (or hand mixer) cream together butter and sugar until light in color and fluffy.
Add eggs one at a time and mix until combined. Scrape down the sides of the bowl to make sure everything is evenly combined.
Stir in the vanilla.
With the mixer on low, slowly add the flour mixture and mix until just combined; being careful not to over-mix.
Scrape down the sides of the bowl again to make sure everything is evenly combined.
Scoop out the dough with a cookie scoop, or two spoons. I make mine about the size of two tablespoons.
Use your hands to roll the scooped dough into a smooth ball.
Combine the coating ingredients together in a small bowl.
Roll the dough ball in the sugar mixture until evenly coated.
Place on a cookie sheet lined with parchment paper.
Repeat with the rest of the dough. Be sure to space the dough balls out on the cookie sheet as they will spread and you don’t want them to touch each other.
Bake for about 9-12 minutes depending on the size, or until lightly golden and the tops start to have those classic cracks on them. Be careful not to over-bake!
Let the cookies cool on a a rack and enjoy! I love these cookies hot and fresh right out of the oven.
