This is a recipe from my Mother's Aunt Cora. It dates back to the early 1900's and was originally written for a wood kitchen stove. We adapted it to our more modern kitchen and its as good as ever. Another comfort food recipe.
Combine flour, baking powder, 1/2 c sugar, milk and salt in a bowl. Pour into greased 9 by 13 inch baking dish or casserole. Heat blackberries and 1/2 c sugar in saucepan until it boils. Pour over batter. Bake at 400 degrees until golden brown, approximately 20-30 minutes.
