Bartolillo is a typical Madrid sweet from Madrid's Holy Week. Halfway between pestiño and sweet empanadilla, it is a kind of crunchy triangle filled with cream.
The dough is made with flour, butter and wine, and then fried. The origin of this light indulgence is uncertain, but its appearance in some texts confirms that it was already eaten in Madrid at the beginning of the 19th century.
