This Chocolate Yogurt Cake from Mel's Kitchen Cafe definitely fits the bill. The yogurt and 5 (!) eggs are the reason for the richness and moisture, no doubt. While it's baking, the chocolate chips fall to the bottom and melt, making a sweet, fudgy layer. On top, I sprinkled on some toffee bits for a little bit of crunch. Top it ith a little whipped cream, and here's a cake I can raise a fork to.
Not that you need a reason to eat cake, but mine is that my birthday is tomorrow! What's your favorite kind of cake?
