Everyone needs a delicious coffee cake recipe in their repertoire, and this cinnamon streusel coffee cake recipe is the perfect option. Meaning "something strewn" in Old German, streusel is easy to throw together -- and then to throw on top of this sour-cream coffee cake. The sweet glaze in the recipe is the perfect coffee cake topping.
European immigrants made this confection -- which has large, crisp crumbs on top -- a New York City coffee-shop favorite. An optional layer of jam between the batter and topping adds a fruity component.
The cake can also be topped with a simple glaze: Whisk together 1 cup confectioners' sugar and 2 tablespoons milk until smooth, then drizzle the mixture over the cooled cake; let set 20 minutes before serving.
