Buttermilk Blueberry Crumb Cake

This blueberry coffee cake is always a hit no matter where I take it. The first time I made it I didn't have buttermilk so I just added a little bit of vinegar to my milk and I let it sit for a minute or so. If you don't want to buy some buttermilk and have the rest of it go to waste, unless you plan on making donuts or biscuits then I would just add a teaspoon of vinegar to your milk.

This is a easy yummy recipe to make.
