Looking for a simple dessert? This coffee cake recipe is an easy, yet elegant crumb cake that’s topped with the most delicious cinnamon sugar streusel. My classic coffee cake is made moist with sour cream and is perfect for a baby shower, holiday brunches or a coffee date with some girlfriends! This homemade version is not like the overly-sweet, fake-tasting store bought versions. The cake has a wonderful buttery, vanilla flavor with the perfect soft and moist texture. Such a perfect treat!
