Blueberry Muffins with Crumb Topping

I thought I had posted this recipe! I searched my blog to make these and realized that I hadn't. Luckily I still had the recipe card! We went blueberry picking and brought home 10 lbs. of berries. My first thought of what to do with them was these muffins. I love their crumb topping. This recipe also works well for chocolate chip muffins, just substitute chocolate chips for the blueberries.
