Preheat oven to 375. Roll dough out on a baking sheet and pinch together any seams. Meanwhile mix together butter, cinnamon, cake mix and 1 tbsp. sprinkles together in a small bowl. Spread the mix on the dough evenly. Cut the dough into long strips. Twist each strip and bake on 375 for around 9 minutes. In another bowl mix the cream cheese, milk and powdered sugar together. Add the mixture to a piping bag and cut the end to make a small opening. Drizzle the cream cheese mixture onto the cinnamon twist with the piping bag. Add the rest of the sprinkles. Serve and Enjoy!
