To make a stroopwafel, start by preparing the dough. Combine flour, sugar, yeast, butter and stroopwafel recipe until smooth. Roll out the dough and cut it into circles. Cook the circles in a waffle iron until golden. For the filling, mix brown sugar, butter, cinnamon, and syrup until thickened. Spread the filling between two warm waffle circles, pressing them together to form a sandwich. Allow the stroopwafels to cool and set before enjoying their delicious caramel center.
