Rainbow JELLO Cubes Recipe (2)

This particular recipe just happens to work for St. Patrick’s Day! It’s so fun to make and easy too! The boys love picking out their favorite flavors of jello and then I put it all together. I say jello “flavors” but really they go by color. You know…”the red jello” or “the green jello”. Whatever works ?

Not only is this dessert beautiful and super-impressive {it looks like it’s really hard to make} but it’s easy on the wallet as well.

You only need some jello, a can ofsweetenedcondensed milk, and some unflavored gelatin. Easy peasy! You can choose whatever colors you like which makes this a very versatile dessert. Layer in the colors of your next party and you’re going to have a yummy treat that’s sure to be a hit!

There’s just something aboutrainbow jellothat bring a smile to my face every time. My boys are also thrilled when I “make rainbows” in the kitchen – they are also HUGE jello fans so this treat is a win-win for everyone.

You can really cut down the calories and sugar in this dessert by using sugar-free jello and low-fat or fat-free sweetened condensed milk. Oh and did I mention this recipe makes TONS of cubes?? Like literally, tons. Depending on how precise I am with my cutting, I usually end up with between 60-80 cubes so there’s plenty for a crowd OR class!

FAQs

How do you layer different colors of jelly? ›

The key to layering up the jelly is never to let the previous layer fully set. It should still be wobbly, not completely firm, or the next layer won't stick. While your first layer is setting in the fridge, crack on with the next coloured jelly and pour it into your mould when the previous layer is just firm enough.

What is the ratio of jello powder to water? ›

Whisk together 1 cup (240 milliliters) of hot water with 1 packet of jello in a large bowl. Keep whisking until no powdery granules remain, about 2 to 3 minutes. If you are using a larger, 6-ounce (170 grams) packet of jello, use 2 cups (475 milliliters) of hot water instead.

What gives jello its color? ›

Food colorings in jello can be either natural or artificial. Due to consumer demand, some products are now being made with natural colorings, such as beet and carrot juice. However, many jellos are still made with artificial food dyes.

Can you add food coloring to Jell-O? ›

Dissolve one of the small 3-ounce boxes of grape or black cherry jello along with 1 teaspoon of unflavored gelatin powder in the boiling water. Stir until the jello is dissolved. Add a few drops of black gel food coloring (affiliate link) until you achieve the desired color.

What color Jell-O makes Brown? ›

Mixing a bit of red into blue will give you a shade that looks more like brown than violet. Factory made shades tend to be more vivid and clear, but not all shades are available, so play around and experiment!

How do you inject color into jelly? ›

Apply a bit of pressure to the syringe to create a tiny color droplet at the needle tip before inserting it into gelatin. Insert the tool into gelatin with the needle pointing up. The needle side of the petal will be more uneven, always keep the needle on the side of the petal that is not going to be visible.

What happens if you don't add cold water to jello? ›

The reason gelatin needs cold water has to do with its gel-forming properties. When gelatin is mixed with hot water, the proteins can clump together, forming lumps that are difficult to dissolve. This is because the heat causes the proteins to denature, or change shape, which can prevent them from forming a smooth gel.

What happens if I put too much water in my jello? ›

You might notice that your jam or jelly is weepy (liquid seeps out of the jell and forms a puddle) or that the jell is stiffer than normal. It's also possible you could experience a more acid taste.

Can you use milk instead of water to make jello? ›

Use 1/2 of the hot water called for. Dissolve the jello, then use the milk instead of water for the added cold water. The milk jello will set on top making a foamy layer. I use to do this to make dessert look fancy for my kids when I only had a budget for jello.

What is the best container to make Jell-O in? ›

If you are making a larger batch, you can use a muffin baking pan to keep the round containers standing straight while the gelatin is setting in the fridge. A half-sphere container with a flat top is the next best choice.

Does Jell-O have to be made with boiling water? ›

Carefully pour 2 cups of warm water inside and stir until the powder is dissolved. You may have to stir longer. Cover the bowl with saran wrap. Refrigerate both bowls until the gelatin is set in at least one of the bowls- about 4 hours.

Can you add food Colouring to jelly? ›

Make it blue - drop one or two drops of green food colouring into your jelly to cancel out the redness and then drop a few drops of blue food colouring in to make it a lovely deep blue colour. Keep testing the colour and mixing until you are happy.

How do you color gelatin? ›

Two easy ways to add natural color to the color base are saffron tea and beet juice. Keep in mind that natural colors come with their own distinct flavor and might react with other ingredients in the gelatin base.

How do you make glowing jelly? ›

It's a very simple idea: you make jelly but use a 1:1 mixture of plain ol' water and tonic water (e.g. Canada Dry). Tonic water contains quinine which is naturally fluorescent and so the resultant jelly will glow under a UV light.

What is purple jelly made of? ›

This unusual jelly gets it's beautiful amethyst color from an infusion of boiling water and wild violet flowers.
