Preheat oven to 375° F.
Grease and flour a 10-inch springform pan. In a large bowl, beat together sugar, oil and eggs. Whisk in buttermilk. In a small bowl, combine food coloring and cocoa. Add to egg mixture. Sift salt and flour into batter and mix well. Combine vinegar and baking soda in a small bowl and add to batter. Immediately pour batter into prepared pan and bake 30-40 minutes. Cool cake in the pan for 10 minutes, then remove from pan and cool completely.
Whip cream cheese until light and fluffy. Add sugar and vanilla. Mix well.
Slice cake horizontally into three equal layers. Place bottom layer back into springform pan. Spread with approximately 1 cup of softened ice cream to make a 1-inch layer. Freeze until solid. Spread blackberry jam on top of ice cream layer and place second cake layer on top. Spread with another layer of ice cream and freeze. Top with jam and last cake layer. Freeze until solid. Unmold the cake onto a platter and coat with cream cheese frosting. Freeze until 15 minutes before serving time. Use a knife dipped in hot water to cut slices. Serves 16-20.
