This moist, dense (but not heavy) coffeecake, aromatic with cinnamon and a buttery streusel topping, offers a thin layer of whole-berry cranberry sauce just below its surface. Add dried cranberries to the batter for a more assertively cranberry cake, if you like; but this version is pleasingly simple. And it's a tasty way to add healthy whole grains and fiber to your family's breakfast. *TIP: If you buy whole-berry cranberry sauce, you'll probably find yourself with a 14-ounce can, with only about 2/3 of it used for this recipe. Can you just go ahead and spread the rest onto the cake? Yes, but it may create more "hills and valleys" in the cake; the volume of sauce will become significant enough to sink down into the cake, rather than lie on the surface under the streusel. All good; your choice.
