Copy Cat Junior’s Black and White Cookies

The first time I saw a Black and White cookie, I was mesmerized. As a child visiting my grandparents in New York, the sheer size and perfect dichotomy of the icing was a marvel. It was more than just a cookie; it was a statement, a perfect harmony of chocolate and vanilla, a taste of the city itself. I remember carefully biting each side, savoring the flavors separately before finally indulging in the beautiful blend when they met in the middle. Recreating that childhood magic is what I hope to achieve with this recipe.

3 tablespoons hot water, plus more as needed
5 ounces bittersweet chocolate, melted (at least 60% cacao)

Equipment Needed

2 baking sheets
Parchment paper
Medium bowls
Large bowl
Electric mixer
Wooden spoon
1⁄4-cup ice cream scoop or 1/4 measuring cup
Small metal spatula
Wire racks

Instructions

Preheat your oven to 375 degrees F (190 degrees C). This precise temperature is crucial for the cookies to bake evenly and achieve the right texture.
Grease 2 baking sheets and line them with parchment paper. This prevents the cookies from sticking and makes for easy cleanup. The parchment paper also aids in even baking.
Sift together the cake flour, all-purpose flour, baking powder, and salt into a medium bowl. Then, sift the mixture again into another medium bowl. Double sifting ensures a light and airy texture for the cookies by evenly distributing the baking powder and eliminating any clumps.
In a large bowl with an electric mixer on medium speed, cream the butter and granulated sugar together until light yellow and creamy. This step is critical; it incorporates air into the batter, resulting in a tender crumb. Be patient and allow the mixture to become truly light and fluffy.
Add the eggs, one at a time, beating well after each addition. Incorporating the eggs gradually ensures they emulsify properly with the butter and sugar.
Beat in the vanilla extract and lemon extract. These extracts provide essential flavor notes that define the classic Black and White cookie taste.
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 are mixed in well. It’s important to alternate adding dry and wet ingredients to prevent the gluten in the flour from overdeveloping, which would result in a tough cookie. Use a gentle hand when mixing to avoid overmixing.
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. Even spacing is important for uniform baking.
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!) Overbaking will result in dry, hard cookies. Look for the specified visual cues to ensure doneness.
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. Cooling the cookies upside down helps to flatten the tops slightly, providing a better surface for icing.
For the Frosting: Sift the confectioners’ sugar into a medium bowl. Sifting the sugar prevents lumps and ensures a smooth frosting.
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. The hot water helps to dissolve the sugar and creates a glossy, smooth frosting.
Transfer 1 1⁄4 cups frosting to another bowl; stir in the melted chocolate and the 3 tablespoons hot water. The melted chocolate must be smooth and fully incorporated into the frosting.
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. Maintaining the correct frosting consistency is key for easy and even spreading.
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. A steady hand and patience are required for achieving a clean, professional-looking division between the two icings.
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, as this can alter the texture of the icing.

Expert Tips & Tricks

For an extra burst of lemon flavor, add a teaspoon of lemon zest to the cookie dough.
If you find your frosting is too thick, add hot water, one teaspoon at a time, until you reach the desired consistency.
To prevent the chocolate frosting from hardening too quickly, keep it in a warm water bath while you are icing the cookies.
For a more uniform cookie size, use a kitchen scale to weigh each portion of dough before baking.
If you don’t have cake flour, you can make a substitute by removing 2 tablespoons of all-purpose flour per cup and replacing it with cornstarch.

Serving & Storage Suggestions

Serve these Black and White cookies at room temperature with a glass of cold milk or a cup of hot coffee. They are perfect for afternoon tea, potlucks, or as a sweet treat after dinner.

Store the cookies in an airtight container at room temperature for up to 4 days. Place sheets of parchment or waxed paper between the cookies to prevent them from sticking together. Do not refrigerate or freeze the cookies, as this can affect the texture of the icing.

FAQs (Frequently Asked Questions)

Q: Why are my cookies flat and spread out too much?
A: The butter may have been too soft when creaming with the sugar, or the oven temperature may be too low. Ensure the butter is softened but still cool, and verify your oven temperature with an oven thermometer.

Q: My frosting is too thick. What can I do?
A: Add hot water, one teaspoon at a time, until you reach the desired consistency. Be careful not to add too much, or the frosting will become too thin.

Q: Can I use margarine instead of butter?
A: While margarine can be used, butter provides a richer flavor and better texture. For the best results, stick with unsalted butter.

Q: How do I get a perfectly straight line between the chocolate and vanilla frosting?
A: Use a small offset spatula and a steady hand. You can also use a piece of parchment paper as a guide.

Q: Can I make the dough ahead of time?
A: Yes, you can make the dough ahead of time and store it in the refrigerator for up to 24 hours. Bring it to room temperature slightly before scooping and baking.
