Banana Blueberry Streusel Cake

Banana Blueberry Cake

Have you ever combined bananas and blueberries before? My kids could not get enough of the moist and dense cake with bits of yummy blueberry and crunchy topping. Just a nice twist on the regular banana bread. You can even use your own recipe and just add the blueberries and streusel topping. I highly recommend it!
