Blueberry Coffee Cake

My new cookbook yeilded this recipe, I added the topping because it seemed just like blueberry muffins in a pan. and then after they baked i realised that it really needed double the topping, so i have already doubled it here. so however you wnat to try it; toppingless, full topping or half it, these were really good.

2 3/4 cups flour

3/4 cups sugar

2 1/2 teas baking powder

1 teas vanilla

3 eggs

1 cup milk

2/3 cup soft butter

1/2 tsp salt

2 cups frozen blueberrys

Topping:
1 cup brown sugar
1/2 cup flour
4 tab butter soft

Mix all ingredients together execpt blueberrys. then gently fold in blueberrys (unless you want purple batter!!!!) pour into greased 9x13 and sprinkle with topping. Then bake at 350 deg for 45 mins.
