Authentic Verweij 100% butter stroopwalfels. This classic Dutch cookie made with 100% real cream butter and a syrupy caramel layer in the middle. For a real treat place a stroopwafel on top of a cup of coffee, tea or hot chocolate and allow the cookie to warm a bit - just enough to soften the caramel filling. Delft is a city in the province of South Holland, the Netherlands. Delft is primarily known for its typically Dutch town centre (with canals); also for the painter Vermeer, Delft Blue pottery (Delftware), the Delft University of Technology, and its association with the Royal Family.
