Eggy -- hi -- how is the baby??? Your question about the "tomato soup" chocolate cake got me thinking. I found the below recipe on Recipe Link. It was posted by Cali 07/25/1998. Humm.. I wonder what happened to Cali. She used to post here a lot. Anyway, you will see she recommended cooking the cake in a bundt pan and making a cream cheeze glaze. Cali posted this as tried and true. Hope this helps. I look forward to replies from other folks here. I hope you are well.

1 1/3 cups sugar
2 eggs
2 cups flour
1/2 cup baking cocoa
1 Tbsp. baking powder
1 tsp. baking soda
1/4 cup water

Add dry ingredients and soup mixture alternately to creamed mixture. Fold in nuts. Pour into pan & bake 30 min. in 9x13" pan, or 40 min. in bundt pan.

I use this cream cheese glaze on the bundt cake:
