A note on the toppings: basically, add whatever you want; I've added frozen strawberries before instead of chocolate, and I've added coffee as well (chilled first). Both are delicious. If the dark chocolate chips don't hurt your teeth, you can just sprinkle them on top without adding them in the last few seconds. Personally, they're too hard on my teeth in chunks. Whatever you add, I'm sure it'll be delicious.
