These Sour Cream Coffee Cake Muffins are a delicious breakfast or dessert with a cinnamon crumb topping and sweet glaze.
Coffee cake is one of my favorite breakfast foods. These baked goods are soft and have streusel on top. This crumbly topping is nutty and a little crunchy.
Did you know you can make muffins with sour cream? You can’t taste it and the sour cream makes the muffin super moist.
