In a large bowl, cream butter and 1-1/4 cups sugar until light and fluffy. Beat in egg yolks, 1 tablespoon honey and vanilla. Combine the flour, baking powder, salt and cream of tartar; gradually add to creamed mixture and mix well.
Shape a heaping tablespoonful of dough into a 6-in. log. In a shallow bowl, combine cinnamon and remaining sugar; roll log in cinnamon-sugar. Loosely coil log into a spiral shape; place on a greased baking sheet. Repeat, placing cookies 1 in. apart. Sprinkle with remaining cinnamon-sugar.
Bake at 350° for 8-10 minutes or until set. Remove to wire racks to cool completely. In a small bowl, melt baking chocolate with remaining honey; stir until smooth. Drizzle over cookies. Let stand until set. Store in an airtight container. Yield: about 2-1/2 dozen.
