Ok Rita, You owe me 4 life. This is the one I use as we grow blackberries. Its very simple. Simply throw all this together there are no special instructions. This was my Grandmother's.

Blackberry Bread

3 cups flour
2 tsp. baking powder
1 tsp. soda
1 tsp. salt
1 cup white sugar
1 cup oil (I use applesauce instead)
2 eggs beaten
1 tsp.vanilla
3 cups blackberries(lightly mashed)
1/2 cup nuts (optional)

Throw it together in a greased loaf pan and bake 35-40 minutes at 350F.

Simple as that. I'm not sure if this is what you want,as it is a quick bread type, but give it a try. It's GREAT...
