Whether you’re looking for a fun and unique party treat for your toddler’s first birthday, a back-to-school snack that’ll have your kiddos smiling big, or a potluck dessert that will disappear in seconds, colorful cubes of Stained Glass Jello are a retro recipe worth reviving.
I came across this idea from Intimate Weddings and was reminded of so many sweet memories that included these pretty treats. My grandma used to make big pans of this colorful gelatin for holidays and it was always my favorite. We’d arrive to find her slicing a pan of pure white, jiggly jello into cubes (or bite-sized rectangle bars or cookie cutting them into stars or hearts), then watch with awe as she gently pulled the gelatin from the pan to reveal a shimmering rainbow.
Though they look tricky to make, whipping up a cake pan full of creamy jello studded with every color of the rainbow is surprisingly simple.
Here’s how to make this fun, edible art:
Create Your Colorful Jello First
Follow the instructions on the back of your flavored gelatin packets and stir together six different colors, placing each in their own 9″ baking dishes until firm. When working with jello, I always prefer to use glass baking dishes because it’s so easy to remove the final product from the naturally nonstick surface.
Cut the Colors Into Cubes
Once your rainbow colored jello has set, slice into 1/2″ cubes with a sharp knife and use a spatula to transfer the cubes into a 9″ x 13″ baking dish. Once all of the colors are in, I found it useful to gently stir the mixture, making sure all of the colors are evenly combined.
Pour White Jello On Top
The recipe below will walk you through this next part. It’s super easy. Using two packets of unflavored gelatin, water, and a can of sweetened condensed milk, you’ll whisk together a milky mixture that is then cooled and poured over the colored cubes.
Note: Make sure you take the time to completely cool this mixture! Pouring hot gelatin over the colored cubes will bleed the colors and make your final product look like a mushy brown mess.
With the cream gelatin poured over your pan, all you’ve gotta do is refrigerate until firm. Though the mixture will be set within two hours, allow it to firm up at least four for best results. You will then get crisper looking servings and cubes that won’t puddle once cut.
Slice & Enjoy!
With a pan full of chilled jello, it’s time to slice into your pan of edible stained glass! Use a sharp knife, dipping it in hot water just before slicing, for extra beautiful cubes. The hot knife makes it easy to make quick cuts into the jello mixture, so you get even edges and beautiful pieces.
As I was slicing our own pan of Stained Glass Jello, my kids were standing anxiously around me, sighing and gasping: “Whoa! It’s so cool! When can we eat it?!” It reminded me so much of my own childhood, standing in Grandma’s kitchen and saying these very things. Some recipes, it seems, always inspire magic. This is one of those.
Stained Glass Jello
original recipe from Intimate Weddings
Makes: 12 servings
Prep Time: 2 hours
Total Time: 6 hours
6 (3-ounce) boxes of flavored gelatin (red, orange, yellow, green, blue, purple)
2 envelopes unflavored gelatin
1 (14-ounce) can sweetened condensed milk
1. Follow instructions on back of gelatin packages and make each color of gelatin in a 9″ x 9″ pan or 9″ round pie dish. Allow to set in fridge until firm. Cut each color of gelatin into small cubes (about 1/2″ square). Use a spatula to remove colored cubes from each pan and place in a 9″ x 13″ baking dish that has been sprayed with nonstick baking spray.
2. In a large bowl, sprinkle two envelopes of unflavored gelatin into 1/2 a cup of cold water. Allow to soften and dissolve for about 5 minutes, then whisk in 1 1/2 cups boiling water and the condensed milk. Stir and allow to cool completely, placing in fridge if desired for 10-15 minutes.
3. Once cool, pour the mixture over the colored gelatin cubes. Cover with plastic wrap and refrigerate until set, about 4 hours or overnight.
4. Then slide gelatin into squares. For easiest slicing, use a very sharp knife dipped in very hot water.
