Mars® bar cake with Mars® bar frosting

    1 hour 15 min

    As sweet as cakes can get! Kids will especially love this chocolaty cake, perfect for birthdays. The icing is optional, but makes it a truly decadent treat. You can use two 20cm or 23cm round cake tins instead of the 25cm ring cake tin, if desired.

    This is absolutely the most delicious cake I've had!!!!!!!!!!  -  26 Aug 2000  (Review from Allrecipes US | Canada)


    Please note: For the frosting to come out right, you need to add 1 tbl of milk. I tried making the frosting twice, throwing out the first attempt because it looked awful, very lumpy and the butter was leaking out. The second time I figured something must be off in the recipe. All it took was a splash of milk for the frosting to smooth out and it turned out perfectly. Overall, the cake is wonderful. The taste is much subtler than what I was expecting, and isn't too sweet. The frosting really gives it the candy taste. I made cupcakes out of this recipe, cooking them for 20 minutes, and they turned out beautifully! Yielded 4 dozen cupcakes and they were gone in a flash. Will definitely make again.  -  19 Apr 2010  (Review from Allrecipes US | Canada)
