You pose an interesting question. When I was much, much younger, the thought of having a meal without dessert was unthinkable. I had an incredible sweet tooth, especially for chocolate.
When I was a young mother with 5 children, I always made a cake of some sort on Monday, with the hopes it would survive until the weekend. Many times it did. Yeah, right.
Now that I'm older, I find that my sweet tooth has waned and I favor sweets a lot less. However, I still am a lover of chocolate and prepare some sort of chocolate "delight" late in the week for us to enjoy.
If there's no dessert goodies in the house, I often grab a handful of chocolate chips to satisfy my sweet/chocolate desires. Buck is deleriously happy with a handful of candy corn. It's his favorite of all time.
