Using this handy little tool from Wilton, you can create a fun Halloween cake. Due to time constraints, I used a boxed white cake mix, divided the batter, and colored some yellow and orange, leaving a little plain white for the center. I would recommend a homemade cake mix if you have the time though, the box mix is only enough for one 9-inch round using this Wilton pan (there is some left over but not enough for a second cake) and I think this cake looks better as two cakes stacked on top of each other. I guess you could use two cake mixes, duh.
After getting your circles of cake colors in their correct position using the handy tool (I don't know if it has a name), pull it out, and VOILA!...your cake is ready to bake!
When coloring the cake mix and getting into the right places in the pan, I use Pyrex measuring cups. I can measure out the right amount of batter for each ring (you need a lot more yellow batter obviously), mix the gel food color right in the Pyrex, and then easily pour it into the pan. Much easier than trying to do it all in regular bowls.
This cake was for a birthday, so with the leftover batter, I made a small example cake that I could cut and show the layers. Doesn't that look great? It's a fun surprise if you don't tell your guests before cutting it open.
Add some star-tipped icing to your cake to coordinate with the colored cake underneath and you are good to go. Just make sure you slice it like a pie, or it won't look like candy corn when you serve it.
