Glass Block Holiday Jello {Festive!}

So a few days ago, I got a text from Sara saying that she noticed I had holiday Jello something on the calendar and was wondering if I was FINALLY posting my soon-to-be-world-famous Jello/cottage cheese/shredded carrot concoction. I texted her back that I was. And then I couldn’t stand myself any longer because if there’s one thing I never joke about, it’s cottage cheese and vegetables in my Jello and told her I was planning on doing this.

Yeah, funny thing, she had taken pictures of the exact same recipe last summer and had never gotten around to it. This is because in spite of the fact that we live thousands of miles from each other, we kind of share a brain. So really, this recipe is from both of us.
I’m actually not a huge Jello fan–I really don’t like the texture and the only times I remember liking straight-up Jello was 1) at Skippers Seafood and Chowder House (has anyone else eaten there? Like…ever? I don’t think I’ve been since I was about 6!) where my mom and I would often dine when I was a kid and 2) after my first c-section when I hadn’t eaten in, like, 36 hours and I was pretty sure that red Jello was the best thing I’d ever tasted. So it is saying a lot when I tell you I thoroughly enjoy this Jello.
Because it is awesome. And your kids will think you’re a rockstar. And grown-ups will start acting like kids (in a silly, Phil Dunphy kind of way and not in an obnoxious Michael Scott kind of way). We had this all the time at birthdays and holiday parties when I was a kid, but I hadn’t seen it in years and then I recently stumbled across my childhood recipe on the lovely Food Librarian’s blog (she has some awesome Jello ideas on her blog if you feel so inclined to peruse!) I was so excited, and so blasted from the past, that I had to make it ASAP.
We’re doing multi-colored Jello here, which I find super-festive,

but you can adapt it for any holiday–red and green for Christmas purists, white and red for Valentine’s Day, green for St. Patrick’s Day, red, white, and blue for the 4th of July, the list goes on and on.

This recipe isn’t hard at all, but it does require a lot of time and planning ahead–to make sure things go ideally, plan on at least 16 hours to make this, just to make sure everything sets up properly.
You’ll need 4 3-oz. boxes of Jello in coordinating/matching/holiday colors. Really, I don’t think the flavors matter–Jello is Jello and it all tastes fruity. It’s kind of like a handful of Skittles–really, they all taste fine together. You’ll also need 1 14-oz. can of sweetened condensed milk (NOT evaporated milk!) and a couple of envelopes of unflavored gelatin (like Knox…is there even another brand?)

Clear out an entire shelf of your fridge. Take 4 small plastic food storage containers; you can use any shape and you can even mix and match. Spray them with non-stick cooking spray and set aside.

Bring about 5 cups of water (no need to measure right now) to a boil. When it has come to a boil, measure out 1 cup of water. Whisk in 1 package of Jello and stir until it’s dissolved.

Pour it into one of the prepared containers:

and repeat with the remaining flavors of Jello and boiling water.

Place these in the refrigerator (uncovered) for at least 4 hours, but overnight is really preferable.

When the Jello has set up, you’ll need to prepare the white “filling.” Sprinkle 2 packets of unflavored gelatin over 1/2 c. of cold water. In the meantime, bring 1 1/2 c. water to a boil (you could totally do this in the microwave in a large glass measuring cup). When the gelatin has stood for 4-5 minutes, add the boiling water and stir to dissolve.

Add in the can of sweetened condensed milk

and whisk the mixture until the milk is fully incorporated into the water/gelatin mixture. Allow the milk mixture to cool while you prepare the color cubes.

Remove the colored Jello from the fridge and carefully cut it into squares.

When I say “carefully,” I mean to try and not have too many jagged edges, but don’t worry about making the squares perfect. Part of the beauty of this Jello is a little variation!

Lightly spray a 9×13″ pan with non-stick cooking spray. Gently toss the cubes together in the pan.

Um…isn’t that the coolest thing ever??
When the milk mixture has cooled (you don’t have to chill it; in fact, don’t do that–it just needs to be about room temperatures), carefully pour it over the Jello cubes.

Some of the blocks will float to the top. You may need to rearrange things a little so you don’t have all of one color in one area of the pan and so the cubes are evenly distributed. Also, poke down some of the floaters so they’re not COMPLETELY protruding from the white mixture.

Place the pan on a completely level surface in the fridge and refrigerate, (uncovered) overnight or at least 8 hours.

When you’re ready to serve, carefully cut these bad boys into squares or rectangles

or you could even use cookie cutters.

Prepare yourself for lots of “oohs” and “aahs“!




  1. I've always wanted to make the rainbow layered jello my Mom made when I was a kid, but it takes all day to make because you have to wait for each layer to set before adding another. WOW she was patient! This recipe has the same effect, but much quicker! My kids will love it!
    And yes, when I saw this post at first, I thought it was fancy soap!

  2. These are one of those COOL foods! I can't get over how beautiful they are! The colors remind me of Fruity Pebbles and they look like mosaics! I tried making Ribbon jello one time. Because of how much work it was and how it melted all over at the picnic, I said the was the first and last time I'd make that. This, however, looks much easier and prettier! Thanks for sharing!

  3. When I was a kid, one of eight, we ate a lot of Jello deserts! I even ordered The Joys of Jello cookbook through the mail, and made them all! I am going to make this for Christmas dinner, because we have two diabetics, and it can totally be adapted for that! Thanks!

  5. that is the craziest but fun thing I have ever seen. so cute. Happy Birthday Kate, both you and Sara inspire me everyday!

  6. I completely agree they do look just like the specialty homemade soap bars out these days! I'll have to try these soon, I'm sure my 18 month old would love them.
