I immediately decided I was going to make a sugar cookie cake. It can be disassembled for packing in a backpack if needed. I am providing a little bag of icing for any fixes that are needed. The candle can be stuck in that little blog of icing at the top.
I like that the cake ended up resembling a Christmas tree. I tinted the icing two shades of teal but after the assembly and the silver balls it really looks more holiday festive than I had initially imagined. But I like it and I hope the birthday girl does too. Her friends can help her eat the cake or the individual frosted cookies I made to go on the hike as well.
I think if I were to do this again for a birthday in any month other than December (where I wouldn't want the cake to look like a tree), I'd use a variety of fun birthday colors for the frosting and sprinkles. The star shaped cookies really make the tree have branches so maybe those could be eliminated as well.
This was a lot of fun to make and decorate. Do you like sugar cookies? They are one of my guilty pleasures!
