Coffee Crumb Cake with Cinnamon and Brown Sugar
A coffee-flavored butter cake layered with a brown sugar and cinnamon crumb topping.
This coffee cake actually contains brewed coffee: one cup of strong coffee goes into the butter and egg batter. The source also makes a cinnamon crumb from flour, brown sugar and cold butter. One line calls for mustard powder among the dry cake ingredients, which conflicts with the sweet method and looks like a translation error; it is omitted here and recorded as an editorial correction. Make the crumble first so its butter remains cold while the batter comes together. Alternate batter and streusel in the pan, ending with crumbs on top. Bake until a skewer from the center has no wet batter; a few buttery crumbs are normal. Let the cake cool enough to cut cleanly.
