Combine berries, sugar and juice in a saucepan and cook uncovered, stirring occasionally for about 5 minutes.
Pour into a greased (I used margarine) baking dish (9 x 9 x 2) if you have it, or if not, I’ve used a casserole dish.
Spread with cake batter (recipe follows) and bake in a preheated moderate oven 375° F for about 20 minutes.
Spoon out servings hot or cold and serve with cream (whipped if preferred).
