Wholesome Yum Allulose sweetener is a natural sugar without the sugar spike. Allulose sugar tastes, bakes, browns, and dissolves just like sugar does, and produces very soft baked goods… all with zero calories, zero net carbs, and zero glycemic index. Use granulated allulose in place of granulated sugar for cooking, baking and topping! Because allulose is 70% as sweet as sugar, you’ll need 1 1/3 cups allulose to replace each cup of sugar.
