    The thought of Mayo in a cake was initially ew, but then remembered Mayo is make of oil and eggs so gave it a go and really glad I did - best cake ever. I used normal cooking milk chocolate and it didn't seem chocolate-ie enough so I put in the the same amount again of dark chocolate. This will be the only chocolate cake I ever make.  -  22 Oct 2013


    At first I thought it was going to be a dud cake, as the batter tasted really weird. But I baked it anyway, and it was 5 stars! It was tested by 3 adults and 7 kids, all of them said "2 thumbs up!" and the 10 year old said "you should go make this cake at a cake making place and be the manager cause this cake is sooo good!". This is a great, chocolatly, thick and creamy cake! YUM  -  08 May 2002  (Review from Allrecipes USA and Canada)


    Don't let the mayonaise deter you.... this is the most delicious cake I have ever tasted. I use sweetened chocolate instead of unsweetened but other than that, I change nothing. The last time I made it, I topped it with "whipped cream cheese frosting" and it was talked about for days. Thanks.  -  28 Oct 2004  (Review from Allrecipes USA and Canada)
