It was just a matter of time before I made this Blackberry Banana Bread, since I love trying different banana bread recipes and blackberry season is in full swing! This recipe makes a nice, full loaf that is dense and moist and full of banana and blackberry flavor. It also has a rich buttery taste and the buttermilk gives it a great taste, too. I think this quick bread works best with fresh blackberries, but if you want to try using frozen, your baking time will be a little longer.
