4 c. blackberries
2 c. sugar, divided
1 c. flour
1 tsp. double acting baking powder
1/2 tsp. cinnamon
1/4 tsp. mace
1/4 tsp. salt
1 c. milk
1/2 tsp. vanilla
1 stick butter, melted & cooled

Toss together the berries and 1 cup sugar. Let stand for 30 minutes. Heat oven to 350 degrees. Sift remaining 1 cup sugar, flour, baking powder, cinnamon, mace and salt. Add milk and vanilla; stir until combined.

Pour melted butter into a 10 inch square pan, 2 inches deep. Add batter, stirring to combine with butter and spoon fruit evenly over it (batter will be very thin). Bake in 350 degree oven for 30 minutes. Increase heat to 400 degrees and bake for 10-15 minutes more or until golden around the edges. Cool 20 minutes before serving.
