Someone asked me to may a "U" birthday cake...any ideas on getting the cake the right shape? Can't find a pan that will work

The Wilton horseshoe pan has a "U" shape.

Or you can make a template of the style and size "U" you want, then use the template to cut a sheet cake to order.

the "U" is far boxier than a horseshoe and it's really wide...depending on what size you need. I'd probably carve it out of a 9X13

There are pans that you can arrange blocks to make the shape (number or letter) you want ... however, the shapes tend to be "boxy" and don't look natural. You'd be better off making a template or cutting free hand.

To do the template you can either print the letter using word or publisher (has more options) then have it to print out poster size & it will print out on more than one page ... then you will use that as an outline to cut the cake.

I also brought letters from my local craft store they are great for an 9x13 pan...if the letter needs to be larger then the template method would be the best route to go
