Monday was the day we celebrate as Columbus Day here in the US, although the actual date is today, October 12. So, you're in luck! You still have time to make this cake!
This is so obviously a "Cool Food For Kids" for Louise's celebration. You can use half of a yellow cake mix, but I suggest instead that you use half of the one bowl yellow cake recipe I found in a Fanny Farmer Cookbook (you can find that here). Bake it in a well greased oval casserole dish, cut a notch in the top so the fo'castle and poopdeck are formed, frost with chocolate frosting (or the mocha frosting at that very same link), and frost. Use a wooden skewer, cut a square sail from a piece of paper. The sail should be the same dimension as the width of your ship. Stick the sail in the middle of the cake, and watch those kids smile!
See? Don't they look happy? Clearly this is a cool food.
And if you don't feel like making this tonight, just make it for Thanksgiving and call it the Mayflower. The kids will be very excited.
Happy Columbus Day, everyone!
