how to customize a store bought cake

For the past few birthday parties, I’ve been the one that made the cake.  I enjoy it and it’s fun to me!  I love being able to completely customize the cake and be as extra as possible.  However, this year I ran into a small, well, a big problem.  I guest list was seeming to be a little large and I wasn’t sure that I would be able to make a large enough to accommodate.  I was going to have to go with a store bought sheet cake but how would it look?  Time to use my imagination and get to work doctoring the giant chocolate confection from Costco.

If you don’t have a Costco membership, I highly recommend it just for these cakes.  These sheet cakes serve about 48 people and cost under $20.  Also, they are delicious!  You can order one ahead of time or just pop in a pick up one that’s pre made.  I went with pre made.  There was one part of this stock cake that really stood out…

The roses!  Four big buttercream roses and lattice piping work.  Gorgeous on any given day, for sure.  But for a Wonka themed party, it missed the mark.  Here’s how I made it into a candy wonderland.

Start by scraping off any details that you don’t want to be included in the final product.  For me, that meant all of the piping and the flowers and leaving the piped edges.  Place all of the excess in a separate container and allow it to come to room temperature.  Once it’s at room temperature, it’s easier to stir and spread.

Spread the combined icing back onto the cake as smooth as possible and place the cake back in the fridge.  When you go to decorate with any figures, toppers, or candy, you’ll want the icing to be set.

Once set, decorate with anything you like.  Card stock cut outs are great for big scenes, like the factory silhouette, and candy can be easily pushed into the top.  If you want to make any specific shapes with sprinkles/edible glitter/etc, cut out your shape from yardstick first.  Place the template onto of the cake (make sure that it is still fairly cold so the paper doesn’t stick) and fill in with your medium of choice.  This is how I made the red carpet coming from the factory.
