1 cup salted butter at room temp
1 cup flour + 2 tablespoons
2/3 cup sugar + 1/2 cup for rolling
1 teaspoon Vain vanilla extract
Sprinkles are optional
Heat oven to 325. Line 2 large baking sheets with parchment paper.
With an electric handheld mixer in a medium bowl, mix together butter and 2/3 cup sugar until combined. Add flour and mix well. Blend in the vanilla.
Roll the dough into 1-inch balls. Roll them in the remaining 1/2 cup of sugar. Put on baking sheet 2 inches apart. Press the balls down with a glass or measuring cup to flatten. If using sprinkles add them now and lightly press down again. The dough should be about 1/4 inch thick.
Bake for 15-16 minutes or until they are slightly golden brown around the bottom and edges of the cookie. Remove from the oven and let them sit on the baking sheet for 15 minutes. Transfer to a cooling rack to cool completely.
