Filled Cronut. So there you go, asking what can it be filled with? What is it anyway? Well, it's a pastry and a donut at the very same time. You see, the baker was bored as usual and decided to make a donut from the croissant dough and low and behold was born the CRONUT!
Fill it with bavarian sauce. You can thank me later. Oh, and get it with a Italian Cappuccino!
