Rainbow Gelatin Cubes Recipe

These perky gelatin cubes are fun to serve and to eat! I vary the colors to match the occasion - pink and blue for a baby shower, school colors for a graduation party, etc. Kids of all ages snap them up. -Deanna Pietrowicz, Bridgeport, Connecticut

"Mine didn't look anything like the one in the picture. The layers were very thin and the last white layer started to thicken, so I put it over a bowl of warm water and that seemed to help a bit. Next time I'll try the microwave for that and maybe a smaller pan than 9x13 so the layers are thicker. Anyone have any comments on this?"

"I thought that I was supposed to wait 20 minutes for the flavored layers and 25 for the milk layer and when I got to the last milk layer, it had firmed up in my bowl so I couldn't pour it. The directions also say that it takes 30 minutes, and it took me hours! I am exhausted! I don't think that they are going to look like the photo when I cut them up..."
