GOOD NEWS...BAD NEWS!!! The flavor of the cake was fantastic!!! However, it took an additonal 15 minutes to bake & it was STILL runny on the bottom...also, I think that next time, I'd add the entire package of marshmallows, cuz I couldn't tell if any were in there. I LUV rhubarb & this cake certainly has potential,,,just needs a few changes. Will most likely make again! THANKS!!!
