Some people call them Half Moons. Others call them Black and Whites. Still other have called them Half and Halfs. But, they are just plain delicious!
I have been wanting to make these for a while; basically, ever since I purchased my copy of
Junior's Dessert Cookbook. I LOVE these tasty treats. They are not really a cake, nor a cookie, but a scrumptious circle of wonderfulness all their own! They even had their 15 minutes of fame in a Seinfeld episode.
Anyway, I finally decided to make these yesterday. While the process of putting them together is a little bit of work, the result is well worth it, as my co-workers can attest to, as I brought some of these in to work today. Try for yourself!
Junior's Black and White Cookies (from the Junior's Dessert Cookbook)
Cookies
2 1/2 cups cake flour
2 cups all-purpose flour
2 teaspoons baking powder
2 teaspoons salt
1 1/2 cups unsalted butter
2 cups granulated sugar
4 large eggs
1 tablespoon pure vanilla extract
1 teaspoon lemon extract
2/3 cup heavy cream
Frostings
10 cups confectioners' sugar (2 1/4 pounds)
1/2 cup light corn syrup
3 tablespoons fresh lemon juice
1 1/2 tablespoons pure vanilla extract
1/2 hot water, cup plus
3 tablespoons hot water, plus more as needed
5 ounces bittersweet chocolate, melted (at least 60% cacao)
For the Cookies:
Preheat the oven to 375 degrees F.
Grease 2 baking sheets and line with parchment paper.
Sift both the flours, the baking powder, and salt together into a
medium bowl. Then, sift the mixture again into another medium bowl.
In a large bowl with an electric mixer on medium, cream the
butter and granulated sugar together until light yellow and creamy. Add
the eggs, one at a time, beating well after each one. Beat in the
extracts.
Sift about one-third of the flour mixture over the batter and,
using a wooden spoon, stir in, then add about one-third of the cream and
stir until mixed. Repeat until all the flour and cream is mixed in
well.
Using a 1⁄4-cup ice cream scoop or 1/4 measuring cup scoop about
1⁄4 cup batter onto the prepared baking sheets for each cookie. Spread
out with a small metal spatula into a 3-inch circle. Space the cookies
about 3 inches apart to bake.
Bake just until the edges begin to turn light golden and the
tops are puffed and spring back when touched, 12 to 13 minutes. The
cookies should be only light golden on the bottom, not golden brown. A
pick inserted into the center should come out clean. (Do not overbake!)
Let the baked cookies cool for 5 minutes on the baking sheets, then
transfer, upside down (bottom side up), to wire racks and cool
completely.
For the Frosting:
Sift confectioners' sugar into a medium bowl.
Stir in the corn syrup, lemon juice, vanilla, and 1⁄2 cup hot water
until smooth. Add more hot water, if needed, a little at a time, until
the frosting is spreadable.
Transfer 11⁄4 cups frosting to another bowl; stir in the melted chocolate and the 3 tablespoons hot water.
Cover the frostings with a damp paper towel to keep them fresh
and spreadable as you work; if the frostings stiffen too much, stir in a
few more drops of hot water.
Using a small metal spatula,, spread white frosting over the
entire flat bottom side of each cookie. When the frosting feels set,
frost half of each cookie a second time, this time with chocolate
frosting, layering it on top of the white and making the center line as
straight as possible. Let the icing dry until it is no longer soft to
the touch, at least 2 hours, and store the cookies, between sheets of
parchment or waxed paper, in an airtight container at room temperature
for up to 4 days. Do not refrigerate or freeze these cookies.
