This year I made a simple cake with a twist. The kids didn't help me make it this year, so I decided to make it a surprise and swirl it red and green inside. The red came out a little pink, but it was still fun.
I made white cake like I normally would. When I got to the step where I would pour it into the pan, I separated it into two bowls and colored the batter with food coloring (and left a little natural colored). Then poured the green into the pan and then the red - kind of making color splats. And into the oven it went.
