This is an Instructable on how to make cinnamon sugar...
You can use cinnamon sugar on buttered toast or topping for quick breads, cobblers, muffins, coffee cakes, oatmeal, applesauce or just about any dessert or breakfast bread.
Step 1: Ratio
Typical proportions of sugar to cinnamon range from 3:1 to 16:1.
1/4 cup granulated sugar to 3-4 teaspoons ground cinnamon. (4:1 to 3:1)
1/4 cup granulated sugar mixed with 2-3 teaspoon ground cinnamon. (6:1 to 4:1)
1/2 cup granulated sugar to 1 tablespoon ground cinnamon. (8:1)
1/2 cup granulated sugar to 2 teaspoons ground cinnamon. (12:1)
1/2 cup granulated sugar to 1 1/2 teaspoons ground cinnamon (16:1)
Note: I find that my favorite ratio is (16:1) but included the others for you to decide.
