Start by cutting your dough into finger-thick discs. Dust your board with flour, roll out the dough to about 1/2 inch thick, and use a heart cookie cutter to shape the discs into turkeys. If the dough sticks, rolling it between two sheets of parchment paper helps.
Place the heart shapes on a baking paper-lined board, then use the remaining dough to create scallop shapes for the turkey feathers. Chill the cookies in the refrigerator for 30 minutes. This step is crucial because it helps the cookies keep their shape while baking—no flat, dull disks here!
Preheat your oven to 392°F (200°C). Bake the cookies for 10-12 minutes or until the bottoms are golden brown. The cookies should stay white on top. Let them cool on a wire rack.
Melt the white chocolate chips in a double boiler. Divide the icing into portions and color some yellow for the beak. Outline and fill in the beak on each cookie. Once the icing sets, add two dots for the nostrils using dark chocolate.
Use white icing to outline the eyes and fill them in. Refrigerate the cookies for about 10 minutes to let the icing set.
Color the remaining icing brick red and spread it over the cookies.
After another 10-minute chill, use more icing to add the red turkey wattle and dark chocolate pupils for the eyes.
