One cup of Splenda granulated sweetener or 24 individual Splenda packets is equal to 1 cup of sugar. When using Splenda sugar or brown sugar blends, 1/2 cup is equal to 1 cup of sugar.
Baked goods made with Splenda may not rise as high as those made with regular sugar. Add 1/2 cup of nonfat dry milk powder and 1/2 teaspoon of baking soda for every cup of Splenda granulated sweetener used in a recipe to increase the rise. Splenda is a zero-calorie sweetener made with sucralose, dextrose and maltodextrin. While Splenda does not contain any gluten-based ingredients, the manufacturer does not test its sweeteners for gluten.
