Preheat oven to 400ºF. Grease cookie sheets.
In a large bowl, combine sugar and butter with an electric mixer until light and fluffy. Add milk, vanilla and egg; beat well. Add flour, baking powder and cinnamon; mix well.
Shape dough into 1” balls. On a lightly floured surface, roll balls into 6” logs. Place on prepared cookie sheets.
Bake for 5-8 minutes or until golden brown. Immediately remove to wire rack to cool completely.
Melt the almond bark or white chocolate in the microwave in a glass pie plate or shallow microwave dish. Microwave on medium for 20 seconds, stir and microwave for another 20 seconds, stirring until smooth. Dip logs into chocolate coating; rolling to coat; place on waxed paper to cool. Drizzle using a spoon with bittersweet chocolate to look like bark on a tree.
