Half and half.... the easy way

Half Chocolate + Half Vanilla = Easy

Most cake pans from Wilton only need one cake mix to fill them so you are forced to choose a single flavor.  A quarter sheet cake is the 9 x 13 size pan.  That's one cake mix.  If you want two flavors in your cake, you'll need to move up to the half sheet, size 11 x 15. Since it takes two cake mixes to fill the 11 x 15 pan, this is the perfect time to add a second flavor to your cake.  When you fill the pan, simply pour one flavor into one side and the other flavor into the other and let them come together in the middle.  You COULD take a knife and swirl around and make more of a marble cake, but it's super easy just to let the flavors meet in the middle.  If you really want to be NEAT about it, create a "dam" in the middle of the pan with a piece of folded aluminum foil.  Once the cake mix is filled into both sides of the pan and meets at the "dam," you can pull out the "dam" and you have a nice neat line separating the two flavors. I've stopped using that method myself and usually just pour one flavor in first, then the second as quickly as possible and hope for the best!

While sometimes it takes longer for chocolate to bake than the vanilla, I've actually found that the cake finishes at the same time when it's baked together like this!  Of course, you could do this method with a smaller pan, but you'll have two halves of a cake mix left over to deal with....but then....that's the perfect excuse for cupcakes!  Don't you think?
