Gevulde speculaas

Gevulde speculaas is a classic Dutch treat: a spiced shortcrust dough layered with a sweet almond paste filling. The dough itself is simple, a mix of flour, brown sugar, speculaas spices, and butter, brought together with milk. While you can bake it right away, letting the dough rest overnight really deepens its characteristic spice notes. The almond paste, softened with a bit of egg, forms a soft layer between two sheets of this fragrant dough.
