To Make Filling:

Remove stems and leaves from blackberries & rinse.  Combine berries, lemon juice, butter, cinnamon and sugar into saucepan and heat on medium until melted.  Set aside.

Batter:

In a separate bowl combine melted butter, sugar, salt and baking powder.  Add cream & stir.  Stir in flour.

Spread batter into buttered, deep-dish casserole.  Pour fruit mixture over batter.  Sprinkle fruit mixture with sugar.

Bake 340 for 45-55 minutes or until golden brown.

This cobbler will reverse itself during baking.  The crust will beautifully rise to the top and the berry mixture will sink to the bottom.  The end result is just what a cobbler should be.
