Marbled marshmallows. What do you think?!
After making Pac-Man Marshmallows, you're going to have small amounts of red, pink, blue, orange and yellow Candy Melts left in little bowls. Don't rinse them out! Instead, scrape the remaining bits into a separate bowl. Drag a toothpick or the edge of the spoon through the colors to mix them slightly, but do not stir or drag too much.
I was able to make 5 marbled marshmallows using just the leftovers from Pac-Man. I put one in Trevor's lunchbox yesterday and it was a big hit with his friends.
