Set oven to 450 degrees. Measure the baking mix into a large mixing bowl and add the sugar, cinnamon and stir together. Add the softened margarine and cut in with knives or a cutter. When mixed together add the vanilla to the milk and then pour into the baking mix and stir together until it forms a stiff dough. Turn this out onto a floured board and knead about 10 times until it has a good texture.
Cut into biscuits and place on a greased baking sheet. I spray mine with a butter spray but you could also baste with melted butter or margarine. Then sprinkle the tops with cinnamon and sugar mixture. Bake these about 12 minutes until the tops are golden brown. Remove them from the pan and place on a plate and add your preferred topping. If you use the glaze, mix together the powered sugar, milk and vanilla. Microwave for 30 second intervals until smooth and creamy. I used cream cheese icing and thinned it with 2 tablespons of milk and heated for 30 seconds in the microwave. Enjoy!
