Vanilla Sugar Cookies

Preheat oven to 350 degrees. Whisk together flour, baking soda, and salt. Beat sugars and vanilla seeds with a mixer on medium speed for 1 minute. Add butter; beat until pale and fluffy, about 3 minutes. Add eggs, 1 at a time, beating well after each addition. Reduce speed to low. Add flour mixture; beat until well combined.

Using a 2-inch ice cream scoop (3 tablespoons), drop dough onto parchment-lined baking sheets, spacing2 inches apart (no more than 4 cookies per sheet).

Flatten cookies slightly using the palm of your hand; sprinkle with sanding sugar. Lightly brush tops of cookies with water using a pastry brush. Sprinkle with sanding sugar again.

Bake until light golden brown, 14 to 16 minutes. Transfer sheets to wire racks, and let cool for 5 minutes. Transfer cookies to racks, and let cool completely.
