     1/2  stick         butter -- optional
   1      cup           sugar
     3/4  cup           flour
   1      teaspoon      baking powder
     1/4  teaspoon      salt

     1/3  cup           sugar -- mix with berries

Preparation:

Place butter in the bottom of a casserole or spray with Pam. Put it in the oven while it is heating. Mix remaining ingredients (batter) and pour into hot casserole (it should sizzle). Spoon fruit mixture over batter and bake 50 min. at 350F. Batter will bubble up through the berries. Cook until top gets brown.
