Apparently, these things are called trdelníks (sometimes referred to as chimney pastries).
A trdelník is a traditional Czech pastry named after its hollow shape, and the pastry's spacious inside serves as the perfect spot to stuff all sorts of delectable fillings.
Unfortunately, you're going to have to take a trip to the Czech Republic if you want to get your hands on one of these bad boys because the pastry shop is located in Prague.
But trust me, these things look totally worth a plane ride across the world.
