Kathie & Hoda's Black Forest Cake

How about a 4-ingredient CAKE that's dairy free, egg free and fat free, using only ONE pan?
Behold Cathy Mitchell, cookbook author of Dump Cakes, to make it happen for us.
Use any flavor soda, any flavor cake mix she says. Oh, I will. The dessert possibilities are endless. (A ton of prepared cake box mixes are accidentally vegan, just read through those ingredients!)
How much does Cathy's laugh make you miss her better half from those grill infomercials? That dude with glasses? Love him.
A hugely sincere thank you to Today for the glorious hour that is Kathie Lee & Hoda - and the glorious cooking segments they bring!

p.s. Cover with foil and bake 20 minutes. Remove foil and bake an additional 30 to 40 minutes or until cake is set. Cool 15 minutes.
