The themed cakes that work are decided on paper, not invented at eleven at night with a piping bag in your hand. Ten minutes of planning is the difference between a cake that looks designed and a cake that looks like everything you owned went on it.
Start with the party, not the cake
Look at the invitation, the balloons, the plates, the outfit. Those decide the colours and the cake matches them, not the other way round. Photograph the party things together and keep that picture on your phone while you shop for colours and toppers.
Three colours, and no more
Pick a base colour that covers most of the cake, a supporting colour for the details, and one accent used sparingly. White, ivory and gold do not count against the three; they are what lets the other colours breathe.
Colour buttercream with gel rather than liquid colouring: liquid thins the buttercream and you need a lot of it to get anywhere. Gel colours also deepen as they stand, so mix your colours an hour ahead and judge the shade then, not straight after mixing.
Pick one hero, not three
A themed cake needs one thing the eye lands on first. That can be an edible image, or a cluster of fondant toppers, or a printed topper standing on the top. It should not be all three. When everything competes, nothing wins, and the cake reads as busy rather than as a theme.
Leave space
Decorations look better grouped than spread out. Cluster them at one point, usually a corner or one side, and let the rest of the cake stay plain. Odd numbers sit more comfortably than even ones: three figures, not four. And leave the area where the writing goes genuinely empty, decided before you pipe it rather than squeezed in afterwards.
Edible images and toppers
An edible image has to be sized to the cake before it is printed, so measure the height and the width of the side, or the diameter of the top, and bring those numbers with you. It goes on last, onto a chilled, smooth surface, and it does not like being moved once it is down.
Fondant toppers and moulded shapes want to be made a day or two ahead so they firm up. A soft topper put onto a cake the same day slumps.
We print edible images and make custom toppers in the shop: edible printing and toppers.
Think about how it travels
A tall cake with a heavy topper on one side is a cake that arrives leaning. Anything stacked needs dowels and a board under each tier, and everything needs to be chilled firm before it goes into the car. Decide that while you are planning, not while you are carrying it out to the driveway.
Write it down
A rough sketch with the colours named on it, the toppers listed and the wording written out will save you an hour later, and it means one shopping trip instead of three. If you would rather hand the whole thing over, we make custom cakes to order.
