    The importance of “spooning” rather than pouring on the next layers should be over emphasized! I’m on layer one and poured...which has caused the layers to come together- that’s okay this is a trial run, a fun Sunday activity with my four year old!

    I can't count how many times I have made this recipe. School, church, potlucks, graduations... The kids and adults love them. It took a lot of trial and error to get it down, but I can do it in about 2 1/2 hrs. If they hadn't turned out perfect the first time I made them, I probably wouldn't have ever done it again. Tips: as soon as you pour out the colored layer, make the next one so that it cools a bit. Microwave slightly if the white layer gets too thick. It takes less time to set as you go along, only about 10 min. for the last 3 layers. The good thing is that once they are cut, the imperfections aren't so obvious. Try to find a level spot in the fridge. Jello boxes work great for leveling!

    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...

    How cute! My kids love these! One of those recipes that people think you took hours to make and lots of effort... Not so! I like using the different colors as well... Makes a stunning display.

    These are so yummy and fun to eat! I love the layers with the condensed milk. They are so simple to prepare. They look very impressive and they travel well.
