My mom is into the southwest stuff so me and my 6 year old daughter made this for her birthday. I used the Wilton wonder mold doll pan and filled it with ice cream. Wish I would have looked at pictures on here before I made the cake... A lot of people used royal icing to make their spikes. We used dry pasta. Wasn't very pleasant when you missed one and bit into pasta while having your cake... Lol :)
