Blueberry almond coffee cake

Since our friends are coming tonight to visit us from Milwaukee, I thought It might be a good idea to make some coffee cake for the next morning.
I always wanted to try the crumb coffee cake so I finally used Ina Garten's recipe and changed a bit to make this cake.
With Sour cream in it, It is so moist and deli sh! I couldn't help tasting(this is the best part anyway)before they came....
