Is it really possible? Zero Calorie, powdered goodness?

With Confectioners Style Swerve, even cupcake frosting can be guilt-free! Swerve is a great tasting, natural sweetener that measures cup-for-cup just like sugar! Made from a unique combination of ingredients derived from fruits and vegetables, Swerve contains no artificial ingredients, preservatives or flavors.

Swerve is non-glycemic and safe for those living with diabetes. Human clinical trials have shown that Swerve does not affect blood glucose or insulin levels. The secret to our zero calorie sweetness is a combination of erythritol and oligosaccharides that provide excellent baking and cooking functionality. And with the ability to brown and caramelize, Swerve is gonna be right at home in your kitchen.
There are no conversion charts needed when baking and cooking with Swerve. If your recipe calls for half a cup of sugar… you simply replace with half a cup of Swerve!
