I have to make a Lego cake...and wanted to bake a rectangular or square cake and then cut it into blocks.
I usually just bake, level and cover with BC or Fondant. Ive never cut a cake into pieces (blocks) and then cover with BC.
Do you think the cake will have lots of crumbs? Im a little nervous cutting the cake into pieces after it has baked!!
Shud I cut it when it is partially frozen? Any suggesitons?
Yeah, partially freezing will help. Just make sure it's room temp before you cover in fondant.
Yes, partially frozen will be best. That is, let the cake come to room temp, then return to the freezer for about 30 minutes. You don't want it frozen solid all the way through. Just the outside needs to be firmed up.
Thin your crumb coat buttercream with milk or water (whatever your liquid is) so it slides on easily. If it's too thick, it'll pull the cake apart as you try to spread.
I know that there are dense cake mixes out there specially to cut down on crumbs, also if the legos are small try using RKT in the shape of blocks
