I made these “Art Deco” vanilla & chocolate shortbread cookies as part of my Christmas cookie assortment, but the colorful sanding sugar edge could easily be modified to suit any occasion. Pink and red would be amazing for Valentine’s Day! 🙂
This recipe was adapted from Bon Appétit, contributed by Chris Morocco. I doubled the recipe, in two separate batches, making the process even easier because I kept one batch to use for the vanilla stripes and the second batch for the chocolate stripes. I also used egg yolks to coat the cookies instead of a whole egg. Wonderful.
Yield: Makes 40-48 cookies
2⅓ cups all-purpose flour, divided
1½ tsp Kosher salt, divided
⅓ cup Dutch-process cocoa powder, sifted
1¼ cups (2½ sticks) unsalted butter, room temperature
⅔ cup granulated sugar
¼ cup powdered sugar
1 large egg yolk
1 tsp vanilla extract or paste
1 egg yolk or 1 large egg, beaten to blend
¼ cup sanding sugar (any color)
- Whisk 1⅓ cups flour and ¾ tsp. salt in a medium bowl. Whisk cocoa powder, remaining 1 cup flour, and remaining ¾ tsp. salt in another medium bowl. These are the bases for your chocolate and vanilla doughs.
- Beat butter, granulated sugar, and powdered sugar in the bowl of a stand mixer on medium-high speed until light and fluffy, about 4 minutes. (Do in 2 separate batches if doubling the recipe, making the vanilla dough first.)
- Add egg yolk and vanilla to the butter and sugar mixture and beat until smooth.
- Divide (for 1 batch) mixture between the 2 bowls of dry ingredients (about 1 cup in each). Scrape vanilla mixture back into stand mixer bowl (save the mixing bowl) and beat on low-speed just until combined. Return to reserved bowl.
- Repeat process with chocolate mixture.
- Arrange 2 large sheets (per batch) of plastic wrap or parchment paper on a work surface. Dollop one-quarter of chocolate dough in the center of each sheet and pat into rough 6×2″ rectangles. Dollop one-quarter of vanilla dough on top of each chocolate slab and pat into rectangles the same size and shape so that you have 2 layers each. Repeat entire process so you have 4 alternating layers.
- Tightly press stacked dough into cylinders about 1½” wide and 8″ long, using the plastic wrap or parchment to help you.
- Wrap logs in plastic wrap and chill until very firm, at least 2 hours. I chilled my dough overnight.
- Place racks in upper and lower thirds of oven; preheat to 350°, preferably on convection.
- Working one at a time, unwrap dough and brush with egg. Carefully sprinkle surface with sanding sugar and roll logs in sugar to coat well (really press dough into sugar so it sticks).
- Slice into rounds a generous ¼” thick, rotating after every few cuts to keep slices round.
- Arrange cookies on parchment-lined baking sheets, spacing 2″ apart.
- Bake, rotating baking sheets top to bottom and front to back halfway through, until edges are just set, 12–14 minutes. Let cool on baking sheets.
Note: Dough can be made 3 days ahead; keep chilled. Cookies can be baked 5 days ahead; store airtight at room temperature.
