Ingredients You’ll Need

2 cups (248g) all-purpose flour: This is the foundation of the cookie, giving it structure. For a gluten-free alternative, you can use a 1-to-1 gluten-free flour blend.
½ teaspoon baking soda: This helps the cookies rise and achieve a soft texture, so make sure it’s fresh.
½ teaspoon salt: A pinch of salt amplifies the flavor of the cookies. Don’t skip it!
10 tablespoons (140g) unsalted butter, softened: Using unsalted butter allows you to control the salt level. Make sure it’s at room temperature for easy creaming.
1 cup (200g) granulated sugar: This sweetens your cookies and helps achieve a tender crumb.
2 large eggs, room temperature: Eggs add moisture and richness to the dough, so bring them to room temperature for better incorporation.
2 teaspoons vanilla extract: Pure vanilla extract enhances the flavor of the cookies; it’s worth the splurge!
⅓ cup (82g) sour cream, room temperature: Sour cream adds moisture and tanginess, keeping the cookies soft and flavorful.
2 ¾ cups (301g) powdered sugar, divided: This is for both the white and chocolate frostings, giving them their sweet and smooth texture.
2 tablespoons light corn syrup, divided: Corn syrup adds shine and helps the frostings set without becoming hard.
1 teaspoon vanilla extract, divided: This is used in the white frosting for vanilla flavor.
2-5 tablespoons warm water, divided: Water ensures your frosting reaches the perfect spreading consistency; adjust as needed.
¼ cup (20g) unsweetened cocoa powder: This gives the chocolate frosting its rich flavor and color.

How to Make Authentic Black and White Cookies

Preheat the Oven: Set your oven to 350°F (175°C) and prepare two cookie sheets by lining them with parchment paper or silicone mats for easy removal.
Mix Dry Ingredients: In a small bowl, whisk together 2 cups of all-purpose flour, ½ teaspoon baking soda, and ½ teaspoon salt. This mixture helps distribute the leavening agent evenly throughout the dough.
Cream Butter and Sugar: In a stand mixer fitted with the paddle attachment or using an electric hand mixer, beat 10 tablespoons of softened unsalted butter and 1 cup of granulated sugar on medium-high speed until the mixture is light and fluffy, usually about 3 minutes. Scrape down the sides and bottom of the bowl to ensure all ingredients are combined.
Add Eggs and Vanilla: Mix in 2 large eggs and 2 teaspoons of vanilla extract until smooth. This step incorporates air, giving the cookies a lovely texture.
Incorporate Dry Ingredients: With the mixer on low speed, add half of the flour mixture until just combined. Then add ⅓ cup of sour cream and mix until combined. Finally, add the remaining dry ingredients and mix until just incorporated; the dough will be soft and slightly sticky.
Scoop the Dough: Using a large cookie scoop (about 3 tablespoons), drop the dough onto the prepared cookie sheets, spacing them about 3 inches apart. This will allow for expansion during baking.
Bake the Cookies: Place the cookie sheets in the preheated oven and bake for 15 to 18 minutes, or until the edges are a light golden brown, and the centers are just set. Remove them from the oven and let the cookies cool completely on a wire rack.
Prepare the White Frosting: Once the cookies have cooled, turn them over to their flat side. In a medium bowl, whisk together 1 ¼ cups of powdered sugar with 1 tablespoon of corn syrup, ½ teaspoon of vanilla extract, and 1 to 2 tablespoons of warm water until it reaches a smooth, spreadable consistency.
Frost with White Icing: Frost half of each cookie with the white frosting, using a spatula or knife to help spread it evenly.
Prepare the Chocolate Frosting: In another bowl, mix together 1 ½ cups of powdered sugar, ¼ cup of unsweetened cocoa powder, 1 tablespoon of corn syrup, ½ teaspoon of vanilla extract, and 1 to 3 tablespoons of warm water until smooth. This will give you a luscious chocolate frosting.
Frost with Chocolate Icing: Use the chocolate frosting to cover the other half of each cookie, ensuring a beautiful half-and-half appearance.
Set and Serve: Allow the frosted cookies to sit for about 20 minutes to let the frosting set before serving.

Storing & Reheating

To store your authentic black and white cookies, place them in an airtight container with sheets of wax paper between the layers to prevent sticking. They’ll stay fresh at room temperature for about 3 days. If you want to keep them longer, freeze them in a single layer on a baking sheet, then transfer them to a freezer-safe bag or container where they can last up to 3 months. The texture may slightly change after thawing, but you can refresh them in the microwave for 10-15 seconds to enjoy that soft, fresh-baked goodness again.

Chef’s Helpful Tips

Be sure your butter is at room temperature for easier creaming; cold butter will not incorporate well, leading to denser cookies.
If your dough seems too sticky, you can chill it for 15-20 minutes before scooping.
For beautifully smooth frosting, mix until no lumps remain; this will give your cookies that professional look.
If you find yourself short on time, you can skip the frosting and enjoy the cookies plain—they’re delicious on their own!
Experiment with flavor variations by adding citrus zest or almond extract for a twist.

The beauty of authentic black and white cookies lies in their simplicity and versatility. They bring joy not just in their taste, but also in the memories they create as friends and family gather to enjoy them. There’s something special about sharing a sweet treat that beautifully bridges different flavor traditions. So, whether it’s for a birthday party, a rainy day snack, or just a delightful moment for yourself, these cookies are sure to impress and satisfy.

Recipe FAQs

How do I know when my cookies are done baking?

Your cookies are done when their edges are light golden brown and the centers look set but might still appear slightly soft. They will firm up as they cool, so avoid overbaking to keep that delightful texture.

Can I freeze the frosting?

While it’s best to frost the cookies fresh for optimal taste and texture, you can freeze the leftover frosting in an airtight container. Just be sure to re-mix it thoroughly once thawed, as it may separate.

What can I use instead of sour cream?

Greek yogurt or buttermilk can be great substitutes for sour cream in this recipe. Both will maintain the moisture and tanginess that sour cream provides.

Can I make these cookies in advance?

Absolutely! You can make the cookie dough ahead of time and refrigerate it for up to 2 days before baking. Just be sure to let it sit at room temperature for a bit before scooping, as cold dough can be difficult to work with.
