There is no official sugar-free version of Brownie Brittle from the company itself, but it is possible to make a homemade version. Many websites have recipes for this, and the most common way to make them sugar-free is to substitute a sweetener such as Splenda.
There are many recipes posted on Pinterest as well as SparkRecipes.com that include healthier versions of the brownies. In addition to sugar-free options there are also low-carb, vegan and gluten-free modifications. In 1992, chef Sheila G. Mains created Brownie Brittle, a crispy brownie snack made to taste like the crunchier edges that form around brownies in the pan.
