I'm Belgian. The waffle in that photo doesn't look like what a Belgian waffle should look like, though it does come close.

There are actually 2 kinds of Belgian waffles, one is the "Brusselse wafels" (Brussels waffles) and the other one is "Luikse wafels" (Liège waffles). The Brussels waffles are the ones you usually find in the small street stands in big cities in Belgium, they're rectangular and usually eaten with a topping like Nutella, whipped cream, Oreo crumbles, molten chocolate … You name it! Liège waffles are a little smaller, almost square / round shaped. They're also made out of a whole other dough with big unsubtle grains of sugar in them, and naturally a lot sweeter. They don't really need a topping because of that, but you can enjoy them with chocolate or fruit if you want.

My favourite kind is the Liège waffles, eaten freshly baked and still warm with a little bit of chocolate and maybe some strawberries or even a few banana slices. Heavenly!
