I’m trying to duplicate this cake. Is this an 8” bottom and a 6” top? And I’m guessing three or four layers on each tier? Also, I’m looking to get it made at Walmart. I know they make two-tier cakes and they’re double layers, but those are a 10 and 6 inch option. Just wondering if they’d make something like this, 3 or 4 layers in a double-tier. Or if it’s too specific for them to bother with. I only need the cake itself, no decorations.
