I think 2 or 3 kinds of coffee (maybe you can add hot chocolate, too) and 5 or 6 desserts will be fine for a coffee-and-dessert party for 20 people. Just don't forget the ultimate dessert of them all -- chocolate cake!!! It comes in different preparations (see my favorites below), so just choose what's best for you and your guests.
Chocolate Decadence Cake
Royal Double Chocolate Cake
Spicy Chocolate Cake
Chocolate Chip Cheesecake
Choco-Coconut Cake Bars
Choco-Banana Pie
Frozen Chocolate Crunch Cake
Chocolate Fudge
Aaaahhhh! Chocolate Heaven!
