Make about 2 dozen cookies
Ingredients
- 1/2 cup (1 stick) unsalted butter
 - 1 cup sugar
 - 1/4 teaspoon kosher salt
 - 3 eggs
 - 1/2 teaspoon pure vanilla extract
 - 1/4 cup sour cream
 - 1 1/4 cups all-purpose flour
 - 1/2 teaspoon baking powder
 
Vanilla Glaze
Ingredients
- 1 1/4 cups confectioners’ sugar, sifted
 - 2 tablespoons light corn syrup
 - 1 tablespoon milk
 - 1/4 teaspoon pure vanilla extract
 
Chocolate Glaze
Ingredients
- 1 1/4 cups confectioners’ sugar, sifted
 - 2 tablespoons light corn syrup
 - 1 tablespoon milk
 - 1 tablespoon water
 - 1/4 teaspoon pure vanilla extract
 - 1/4 cup cocoa powder
 
Directions
- Preheat the oven to 400°F. Line two baking sheets with parchment paper.
 - In the bowl of a stand mixer fitted with the paddle attachment, cream the butter, sugar, and salt on medium speed until light and fluffy, 3 to 4 minutes.
 - Add the eggs one at a time, scraping down the bowl after each addition. Add the vanilla and sour cream and mix to combine.
 - In a medium bowl, combine the flour and baking powder. Slowly add to the creamed mixture, mixing on low speed just until combined. Scrape down the bowl as needed.
 - Scoop the dough onto the prepared baking sheets using a #40 scoop (about 2 tablespoons) about 1 1/2 inches apart.
 - Bake until just golden around the edges, 8 to 10 minutes. Rotate and switch the baking sheets as necessary for even baking.
 - Allow the cookies to cool for a minute on the baking sheets then transfer, using a spatula, to a cooling rack and allow to cool completely.
 - While the cookies are cooling, make the vanilla glaze: In a small bowl, combine the confectioners’ sugar, corn syrup, milk, and vanilla. In another small bowl, make the chocolate glaze: Combine the confectioners’ sugar, corn syrup, milk, water, vanilla, and cocoa.
 - Using a spatula, spread half of the top of each cookie with the vanilla glaze. Let sit for 10 minutes to level and set slightly.
 - Spread the chocolate glaze on the other half of the cookie tops, to the edge of the vanilla glaze. Let sit to level and for the glaze to become firm.
 - Store the cookies in an airtight container.
