Ingredients

2¼ cups all-purpose flour
½ teaspoon cinnamon
½ teaspoon salt
¾ cup (1 ½ sticks) unsalted butter, softened
¾ cup granulated sugar
2 egg yolks
1teaspoon vanilla

3. Babe at 350º for 15 to 18 minutes, or until lightly golden. Transfer cookies to rack; let cool.
4. In a medium-size glass bowl, microwave chocolate on High for 30 seconds, stirring until smooth. Spread each flat cookie bottom with 1 teaspoon melted chocolate. Dry, chocolate side up, on wire racks (30 minutes). Once dry, remelt remaining chocolate in bowl. Transfer to a plastic bag; snip off a small corner. Flip cookies over (chocolate side down) and drizzle stripes. Let dry.
