I used this recipe. The only difference was that my blueberries were frozen.

Put together the first 3 ingredients into a square baking dish.
Put the next 3 together in a small bowl.
Mix up all the rest in a large bowl.
Put dry and wet together.
Then dump it by the spoonful over top of the blueberries, aiming at heavy coverage.
My four year old helped, but we still covered it rather well.
Throw on some stuff. We used whipped topping, but ice cream or home made whipped cream would be fabulous, too.
