Author Notes: Black and white cookies are the perfect marriage of chocolate and vanilla, cookie and cake. They are a classic deli treat, usually about 5 inches in diameter, but here I've made them mini which I find is a much more reasonable amount of cookie. The icing contains one tablespoon of light corn syrup (which is not the same as high fructose corn syrup), but if you’d like to avoid it, just leave it out. The icing on your cookies will just dry a bit harder and it won't be quite as shiny as it would with the corn syrup. This recipe is adapted from Gourmet. —Yossy Arefi
Makes about 3 dozen cookies
For the cookies
- 1 1/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/3 cup buttermilk
- 1 teaspoon vanilla extract
- 6 tablespoons unsalted butter
- 1/2 cup granulated sugar
- 1 large egg
For the icing
- 1 1/2 cups confectioner's sugar, sifted
- 1 tablespoon light corn syrup
- 2 teaspoons lemon juice
- 1/2 teaspoon vanilla extract
- 2 tablespoons water
- 1/8 teaspoon salt
- 6 tablespoons cocoa powder, sifted
- 1/4 teaspoon instant espresso powder
- Preheat oven to 350º F and line two baking sheets with parchment paper
- In a small bowl, whisk the flour, baking soda, and salt together.
- In the bowl of a stand mixer, beat the butter and sugar until creamy. Add in the vanilla extract and egg and mix until well combined. Scrape down the bowl.
- Alternate adding in the flour mixture and buttermilk in 3 additions. Mix until just combined.
- Use a tablespoon measure (or pastry bag) to portion the cookies 1 inch apart on the baking sheets. Bake the cookies for 6 to 8 minutes, or until the tops spring back when pressed gently and the cookies are a light golden brown around the edges. Cool completely.
- While the cookies are cooling, prepare the icing by whisking the confectioner’s sugar, corn syrup, lemon juice, vanilla, salt, and water together until very smooth. Remove half of the mixture to another bowl and whisk in the cocoa powder and espresso powder until very smooth. Add a few drops of water to the chocolate icing until it is a spreadable consistency. The icing should be thin enough that it is easily spreadable, but not runny. If it seems dry, add water 1/2 teaspoon at a time; if it is runny, add confectioner’s sugar 1 tablespoon at a time.
- Flip the cooled cookies so their flat sides are up. Use an offset spatula or knife to spread vanilla icing on half of the cookies, then spread chocolate icing on the other half.
- Let icing set for a few minutes, then dig in. Store the leftover cookies in an airtight container at room temperature for up to two days.
