Adapted from Genuine Pizza
2 sticks cold unsalted butter, cut into several pieces
3/4 cup +2 tablespoons granulated sugar
3/4 cup +1 tablespoon packed dark brown sugar
2 large eggs, cold
2 teaspoons vanilla extract
3 1/2 cups all purpose flour
1 1/2 teaspoons kosher salt
1 1/2 teaspoons baking soda
12-24 miniature Snickers, Milky Way, or Three Musketeers bars, unwrapped
Preheat oven to 350° F. Line 2 cookie sheets with parchment; set aside.
In a stand mixer fitted with a paddle attachment, cream together butter and sugars on medium-high speed until light and fluffy. Add eggs, one at a time, until fully incorporated. Pause the mixer motor to scrape the sides and bottom of the bowl between each addition. Add the vanilla and mix to incorporate.
In a separate bowl, whisk together flour, salt, and baking soda until combined. Add the flour mixture to the butter-egg mixture and mix on low speed until just combined. Do not over mix
Using a cookie scoop (see note below) scoop dough into your hand, and roll into a ball. With your thumb, shove an unwrapped miniature candy bar into the ball, and roll again to seal. Place two inches apart on parchment-lined cookie sheet and flatten slightly. Bake for 20 to 22 minutes, or until they are golden brown and about 1/2 inch thick. Remove from oven and transfer to a wire rack to cool. Allow to cool completely, then transfer to a container with a lid and store at room temperature for up to a week.
NOTE: If you use a 2-ounce cookie scoop, as directed, you will get 24. For larger cookies, use a 4-ounce ice cream scoop, bake for 28-30 minutes, yielding 12 cookies.
