A classic sour cream coffee cake with a big cinnamon streusel layer, buttery crumb, and optional vanilla glaze. Simple ingredients, clear steps, and reliably...
There are two kinds of mornings: the ones where you are ready to do a whole thing, and the ones where you need something sweet, warm, and low-drama with your coffee. This Bisquick coffee cake is for the second kind, but honestly it hits hard enough for the first kind too.
You get a tender, vanilla-scented crumb underneath a buttery cinnamon streusel that bakes up crisp at the edges and a little sandy in the best way. It is the kind of cake that disappears slice by slice while people “just grab a little piece.”
