Can aspartame be used in cooking or baking?
Yes. Several tabletop sweeteners containing aspartame as the sweetening ingredient can be used in a wide variety of recipes. However, in some recipes requiring lengthy heating or baking, a loss of sweetness may occur; this is not a safety issue — simply the product may not be as sweet as desired. Therefore, it is best to use tabletop sweeteners with aspartame in specially designed recipes available from the manufacturers of these tabletop sweeteners. Aspartame tabletop sweeteners may also be added to some recipes at the end of heating to maintain sweetness.
