"I am having trouble getting the semi-sweet chocolate chips and butter the right consistency so that they don't tear up the cake. I let cake sit 5 minutes or longer as advised. Suggestions please."

"Very delicious cake, but I tried to make it in a layer cake and did not work.My chocolate layer was like a chocolate shell, not sure what I did wrong. Will make again I may have to tweak the chocolate fudge."

"WOW! Was this ever a hit at my house. My daughter and her two sons say they don't like white chocolate, so being the type of grandma who wants the kids to try new tastes, I didn't tell them there was any white chocolate in the cake or in the topping. The children ate with gusto and sang my praises about this being the best cake ever! When my daughter tried it, she stopped eating long enough to say,

"Mom, this cake is the Bomb! What's in it?" Well I couldn't lie to her, so I told her, and she asked for a piece to take home."
