Sometimes the best decorations are the simple kind. Like good ole polka dots! And why stop at polka dots on the outside of the cake? Let's put polka dots on the INSIDE of the cake!! It really is quite simple, the first time I saw this technique it was from Snowy Bliss, check out her great tutorial. Bake cake balls in one of the many pans available these days, electric or oven will work. Then you just drop them randomly into your cake pan before you bake up the cake. Yes, add the cooked cake balls into the raw cake batter and then bake.... It might seem weird, but I promise everything works out just fine.
