Black and White Cookies
Ingredients*
Cookies:
1 ¼ cups all-purpose flour
½ teaspoon baking soda
½ teaspoon salt
1/3 cup well-shaken buttermilk
½ teaspoon vanilla extract
5 1/3 tablespoons unsalted butter, softened
½ cup granulated sugar
1 large egg
Icing:
1 ½ cups confectioners’ sugar
1 tablespoon light corn syrup
2 teaspoons fresh lemon juice
¼ teaspoon vanilla extract
1-2 tablespoons water
¼ cup unsweetened Dutch-process cocoa powder
Instructions*
Put a rack in middle of oven and preheat oven to 350 degrees Fahrenheit
Whisk together flour, baking soda, and salt in a bowl
Stir together buttermilk and vanilla in a cup
Beat together butter and sugar in a large bowl with an electric mixer at medium speed until it is pale and fluffy, about 3 minutes
Add egg, beating until well combined
Reduce speed to low and add flour mixture and buttermilk mixture
Spoon ¼ cup amounts of batter about 2 inches apart onto a buttered baking sheet
Bake until the tops are puffed and pale golden and cookies spring back when touched, 15-17 minutes. Transfer to rack to cool
Stir together confectioners’ sugar, corn syrup, lemon juice, vanilla, and 1 tablespoon water in a small bowl until smooth
Transfer half the icing to another bowl and stir in cocoa, adding more water ½ teaspoon at a time to thing to the same consistency as the white icing
Turn cooled cookies upside down
With a small spatula, spread white icing over half of each cookie and then spread chocolate icing over the other half
Let cookies stand still until icing is set, about 2 hours
