My son loves this cake so much that he did a speech in school on how to make it. He got an A and the class inhaled the cake.

When I saw this recipe, I knew I had to try it. My mother's house sits along the Ohio River. My husband and I joked about how if they knew what was really on the bottom of that river they would never want to eat this. I loved how easy this was to make and how interesting the technique was. The "sludge" at the bottom was the best part. I'll be making this again for all our family in Ohio.

I was told to give this cake 5 stars as I made it, but didn't get to try it. I gave it to family as a "thank you gift" They tried to save some for me to sample but said it was just too good :) So, I will be making it again. Thanks so much, it looked delicious!
