Preheat oven at 375 F.
Soften cut butter by microwaving it until soft but not melted.Set aside.
In a large bowl, mix together flour and next 4 ingredients and egg plus the 1 teaspoon ginger. Mix all of the ingredients using your pastry blender, or in my case, I used my hands since I don't have pastry blender.
Mix until the ingredients will look like a cookie dough. Reserve 1 cup of dough and press the remaining dough into the bottom of baking pan.
In another bowl, stir together blackberries and remaining 2 ingredients and remaining 1 teaspoon fresh ginger. Pour mixture over dough in pan and sprinkle or place reserved dough on top of fruit.
Bake for 45 minutes or until top is golden brown and bubbly. Let cool before serving.
