attempt at an ombre cake

i was looking around on all the baking blogs out there and the ombre cakes caught my eye. naturally, i had to try it out! good thing my neighbour was getting married so i had an excuse to whip it up as a gift. haha. this is a 6 inch vanilla cake with a 3 inch tier, layered with nutella and frosted with buttercream. i hope it's as yummy as it sounds, didn't get to taste!
