There is nothing quite like the glorious smell of yeast cake baking in the oven. My mom always says that the smell turns the house into a paradise. She really loves yeasty, sweet treats, so good son that I am, I often bake this cake for her. My version combines a rich buttermilk dough with the refreshing flavors of berries and the crunch of buttery streusel topping. Drizzle this heavenly, fluffy cake with honey or powdered sugar and watch how quickly it disappears.
