Buttermilk Breakfast Cake Variations

While the blueberry version of this cake is absolutely delicious, there’s no reason why you can’t use other berries and even other fruits.

Try it with blackberries, raspberries (YUM!), and even peaches. You can use these fruits frozen as well: just toss them in right out of the freezer.
