This is a very easy mold to make, but does require an approximate 3 hour time commitment from start to finish. You will not be in the kitchen the entire time, but will need to add layers every 10-15 minutes or so. So, pick a day when you will be doing stuff at home anyways and I promise it will be well worth the time!
- 7 3 oz. packages of gelatin
- 1 purple
- 1 blue
- 1 green
- 1 yellow
- 1 orange
- 2 red
- 1½ cups vanilla yogurt
- 8¾ cup boiling water
- First, dump your gelatin powder into 6 individual containers. The containers need to be able to hold at least 1¼ cups of hot liquid. You will need a bigger bowl (one quart) for the cherry one as you will be using two boxes of that flavor.
- Next, stir 1¼ cups boiling water into each flavor (2½ cups for the red). Stir each until gelatin is completely dissolved. You will want to position your glasses in opposite order of the rainbow as we will start with purple and end on red.
- Spray your bundt pan with cooking spray, this will help the Jello mold release easily once it is set.
- Add ¾ cup of your purple gelatin into the bundt pan and then place in the refrigerator for 15 minutes. Make sure you set a timer for each layer as knowing when to add the next layer is very critical. You must chill each layer long enough to partially set, but not too long otherwise the next layer will not adhere.
- Take the remaining purple gelatin and add 1½ Tablespoons of the yogurt and stir until completely dissolved. Make sure there are no yogurt lumps left. Place this mixture into the refrigerator to chill until your first 15 minutes is up.
- Once your timer goes off, take your bundt pan and yogurt mixture out of the refrigerator. You will first want to test the gelatin in the pan to make sure it is set enough to take the next layer. You will test this by lightly touching the jello with a finger tip and lifting up right away.
- The jello should stick to your finger (not liquid) and leave a slight impression in the jello. If you have that, then you are ready to add your next layer.
- Now you want to add your yogurt mixture. With a spoon very GENTLY and SLOWLY add your yogurt mixture to the set jello layer. Make sure your spoon is nice and low when you are adding the yogurt mixture. This will ensure you don’t break through the bottom layer when you pour it in. Place back into the refrigerator for another 15 minutes.
- Complete this same process with the rest of your colors. Red will be your last layer, which will be a double layer. Use 1½ cups of the liquid jello for the clear layer and 1 cup mixed with 5 Tablespoons yogurt for the creamy layer.
- The other jello colors can remain on the counter during this entire process.
- I have never had any of the waiting jello start to set. If this should happen though, simply fill a bowl with hot water and place your jello container inside of the water bowl and stir until the set jello loosens up and turns back into liquid.
- Your cooling time will lessen with each layer added as the cooler the jello gets, the less time it takes to set. Also, each layer gets thinner and thinner so will chill quicker. So each layer might not take the entire 15 minutes. When I get to the green layer I start checking around 10-12 minutes and adjust accordingly.
- Once you have added all 12 layers, let the filled mold set overnight.
- When you are ready to release the mold, simply fill your sink with warm (not hot) water. The water should cover the majority of the bundt pan, but should not come all the way to the top. You do not want any water to get into the jello mold.
- Let your mold sit in the warm water for about 10-15 seconds. You will see the side of the jello get a little shiny and liquefy slightly. That is a good sign that the jello has separated from the mold.
- Once you see that, take your mold out of the water and dry off the pan. Take the plate that you will be serving the jello on (should be flat and at least 2-3 inches wider than your mold) and sprinkle a couple drops of water around where the jello will be touching the plate. This will allow the jello to adjust and spread a little once it is released. Now place the lightly moistened plate over the jello mold. With a good grip on the mold and plate, flip the plate and mold over. Slowly lift your mold and the jello should release easily. If any water has accumulated on the plate around the jello, simply take a paper towel and wipe until clean and dry.
- Keep refrigerated.
