Soft and Chewy Sugar Cookies (Drop-Style)

In a large mixing bowl, cream together the butter, granulated sugar, and brown sugar at medium speed until light and fluffy, about 3 minutes, scraping down the sides of the bowl with a rubber spatula as needed. Add the egg and vanilla; beat at medium speed until combined, about 30 seconds. Add the dry ingredients and beat at low speed until just combined, about 30 seconds, scraping down the bowl as needed.

Place the ½ cup sugar for rolling in a shallow bowl. Fill a medium bowl halfway with cold tap water. Dip your hands in the water and shake off any excess (this will prevent the dough from sticking to your hands and ensure that the sugar sticks to the dough). Roll a heaping tablespoon of dough into a 1½-inch ball between moistened palms, roll the ball in the sugar, and then place it on the prepared baking sheet. Repeat with the remaining dough, moistening your hands as necessary, and spacing the balls about 2 inches apart. Butter the bottom of a drinking glass and then dip the bottom of the glass in the remaining sugar. Flatten the dough balls with the bottom of the glass until they are about ¾ inch thick, dipping the glass in sugar as necessary to prevent sticking (after every 2 or 3 cookies).

Bake until the cookies are light brown around the edges and their centers are just set and very lightly colored, 10 to 13 minutes. Cool the cookies on the baking sheets about 3 minutes; using a wide metal spatula, transfer the cookies to a wire rack and cool to room temperature. Store in an airtight container at room temperature for up to 5 days.
