I do have a specialty. Ask anyone that knows me and they’ll tell me that I love making desserts. I also love staying home and being anti-social, but that’s another story for another day.

If my family could live off desserts, it would be all I cooked. Unfortunately, society frowns on cookies for breakfast, brownies for lunch, and cake for dinner.
