Update - I used the crumb layer on my fully piped cake
I found this #1 pan at the thrift store and was inspired for my son's first birthday 😊 I've never iced a cake in my life but watched 100 videos to prepare. I did a trial run with flat icing on the sides and it was a fail. This was trial #2 with fully piped sides.
Issues
1. Food colouring turned way darker than expected
2. I did not cover the cake in the fridge and the icing tasted a bit like "fridge".
3. Buttercream was melting from my hands as I was piping and I had to put it into the fridge a lot
