Dutch Doughnut Does anyone know the name of it?

In the past whenever i visited Netherlands, i used to buy this cream filled chocolate glazed doughnut which resembles to boston cream filled donut but much much better tasting. Cream is extremely light, chocolate is like heavenly tasting... It is much thicker and fuller, it makes you wanna eat more and more. I can't find the name of it. Does anyone know what i am talking about? It is very common in Holland, you would find it in bakeries .
