I used a wire cooling rack to hold the cake shooters. I used upside down cups to elevate the cooling rack and just put the shooters in the holes. Not very elegant but it worked like a charm!
We spent quite a bit of time experimenting to find the best process. In the end we used a 1 1/2 inch piece of metal pipe (found in the plumbing department of the hardware store) and a piece of 1 inch PVC (also found at the hardware store). Cut the cake with the metal pipe (cuts smoother) and push it out with the PVC. If you have 2 people working together it is very simple. One of us cut and popped the cake into the shooter and the other frosted and we just handed them back and forth.. We did 24 in about 5 minutes. We used an upside down plastic tray used by the soft drink companies (with holes in them) to hold them upright. We have a party for 175 coming up and will put them in a 2x6 with holes in it to stand them up. I carried them in a tote bag to work (show and tell..lol) and they help up perfectly.
Has anyone frozen these and served them a several days later? We would like to do this but I am concerned about how they will hold up and taste.
