If you do not have baking mix available, you can use alternative methods to complete the recipe. For the sweet baking mix, you can use sugar, powdered milk, salt, and baking powder. If needed, you can also add cream of tartar to your mix. The mix also needs shortening or vegetable oil, whatever is available. For low dairy or low-fat mix, you need to revise the portion of powdered milk and use shortening with reasonable fat content.
