This was for a boys 1st Birthday .10 in. & 6 in. vanilla & buttercream, w/ 4 in. smash cake. This was my first time making a square cake and a first time for stacking a cake. Could not find (in time crunch) a 6 in. pan or 4 in. so I had to cut out of 8 in. Was not fun! I am happy with how it turned out. Any constructive criticism is welcome. TFL
