Desserts are indeed an extravagance for many of us, especially in the cleanse-mania month of January when people seek to shed a few of their holiday pounds. But I'm also a big fan of not going overboard with deprivation and feel that everyday meals should be just as celebrated as special occasions. So my middle-way solution is to bake a single layer cake and dust it with powdered sugar.
For me and my small household, a 9" cake lasts an entire week. After dinner or even occasionally after lunch, I cut a simple wedge of cake and serve it on a pretty plate. Suddenly a humdrum mid-week meal becomes a little more special. It always makes me smile. Also, having a little cake in the house means you can have someone over for afternoon tea, which is a practice I highly recommend.
Keep your cake fresh by wrapping it in plastic wrap or keeping it in a cake tin or tupperware. If it starts to dry out, try serving it with a little jam spread over the top. Or melt the jam in a saucepan and pour it over.
Don't get me wrong: frosting is very, very nice and I would not want to live in a world without it. But a frosted cake as an everyday thing is a little over the top, in my book. With a small wedge of unfrosted cake, we can still indulge. This is definitely a solution to the having your cake and eating it too problem!
These cake recipes from The Kitchn's archives would make great single layer cakes. Just cut the recipe in half and bake in a 8 or 9" pan. Or again, make two layers but freeze one for later. And skip the frosting!
