Results of my baking frenzy the other day:
Checkerboard cake. I tried using one boxed cake mix for this and the layers turned out a bit flat. Next time I'll use a full mix (or recipe) for each color.
This is how the slices looked packaged in plastic clamshell containers.
The Weather Map Cake. I hadn't intended for it to look like a weather map, but once I realized it did, I went with it. Inside, the cake is chocolate and the filling is black raspberry.
The Sunface Cake. Inside, the cake is yellow with lemon curd filling.
