I had to make a cool bowling cake for a friend super fast- here it is.! First, I baked a 9x13 cake. I also poured some cake batter into a glass pyrex bowl, and baked that to form the 3D curve of the bowling ball. Once everything cooled, I spread green icing on the surface of the cake. I attached the bowling ball, and covered it with marbled various shades of orange. To finish it off, I piped bowling pins flying away from the speeding ball and a triple X Strike!
