Gelatin Bubbles

I had never made gelatin bubbles before, but was asked to make a bubble gum-inspired cake

Gelatin bubbles had always intrigued me, but seemed so complicated. I also despise unflavored gelatin, but had to put my feelings aside for this project.

Making gelatin bubbles turned out to be easier than I thought they would be, but they take FOREVER to make. The active time isn’t too bad, but they take quite a while to dry.

I followed Cake Central’s tutorial as a starting point, and learned a ton throughout this process. 

I will share my gelatin bubble triumphs, like having some of my gelatin bubbles actually end up being circular!

And I will also share the struggles I had. I repeat, do not turn a fan on and point it directly at the balloons while drying them…they WILL fly off your counter!!

Clearly, making these gelatin bubbles was an emotional roller coaster. But I promise, this story has a happy ending.

Hopefully you can use the tips I share below to easily make perfect gelatin bubbles.

The recipe included below makes enough bubbles to cover the top of an 8-inch layer cake.

Tip #1: Keep Your Gelatin Warm

The first problem I ran into when making these bubbles was keeping my gelatin the right consistency. If it cools off too much, it’s hard to dip the balloons in, and gets kind of a goopy texture.

At the time, I ended up making three different batches of gelatin. However, I think making one large batch, and placing the bowl above some warm water might be a better solution.

The most important thing is to keep an eye on the gelatin, and heat it up if it gets too thick. No one wants a lumpy, uneven gelatin bubble!!

Tip #2: Use Small Balloons, And Don’t Inflate Them Fully

As I began this project,  I blew up some small balloons into varying sizes (1 inch to 3 inches in diameter).

I did my best to shape them into circles. But you know what? BALLOONS AREN’T CIRCLES! They are oblong. My makeshift way around this was to tie the knot very high up on the neck of the balloon.

This was easiest to do when the balloons weren’t fully inflated. I recommend leaving yourself a bit of room to work with when blowing them up.

Tip #3: Coat Your Balloons With Shortening

Trust me on this one. It is absolutely essential that you lather up your balloon with a thin coat of shortening. This step allows you to get the balloon out from under the hardened gelatin.

While you may be tempted to completely slather the balloon with shortening, you actually do need to be sure you only add a thin layer.

If you don’t wipe away any excess shortening (white areas), the gelatin won’t stick to the balloon and take shape.

Tip #4: Carefully Use A Fan To Help The Gelatin Bubbles Dry Faster

This tip helps speed up the drying process. Without a little breeze, these gelatin bubbles can take up to 12 hours to firm up.

I don’t know about you, but I don’t have the patience or the time to wait overnight!! If you do have the time and a safe area you can let these dry, by all means go for it.

If you want to speed this process us, you can use a small fan on a LOW SPEED to accelerate the process.

In full transparency, when I first pointed my fan at my bubbles, 1/3 of them flew off the counter and fell on the ground.

Start by placing the fan a safe distance away from the bubbles, on the lowest possible speed. With the help of the fan, my bubbles (that survived) dried after about 4 hours.

One strange thing to keep in mind as the gelatin firms up. The gelatin will actually contract a bit, and shrink. This will create loud, crackling sounds.

At first I was convinced my bubbles were shattering, but was relieved to realize it just meant they were firming up quickly!

Tip #5: Popping The Balloons

You’ve now invested hours into the gelatin bubbles. And you’re supposed to just take scissors to them and pop the balloons?!

I know it seems scary, but I promise your bubbles will be strong once they’ve dried. It also helps if you use a good, sharp pair of kitchen scissors.

The balloon should easily pull away from the bubbles, thanks to the shortening we spread on them! 

There were a couple places where I skimped on the shortening, and the balloons got indented as I removed the balloons.

At first I was pretty upset. Then, much to my surprise, I realized I could simply pop out the intend!! 

Like I mentioned earlier, you’ll be shocked by how sturdy your balloons end up being. This is also what makes it easy to trim the jagged edges with scissors.

Tip #6: Making Gelatin Bubbles In Advance

These can be made several days ahead of time, as this process is rather time consuming!

The bubbles can be stored in an airtight container for several days. 

I couldn’t resist sharing a shot of the cake I decorated with these bubbles! One the bubbles were dry, I used them to decorate this buttercream cake. I simple pressed them into the buttercream!

DISCLAIMER: I do not recommend actually eating the bubbles. Although they are edible, they don’t taste great (plain gelatin!!). 

As you make them, the distinct and unpleasant smell will indicate how they would taste. These are much more  of a decorative touch than an edible garnish.

Additional Tools


  1. Begin by adding 12 Tbsp. of cold water to a bowl. Pour in 6 Tbsp of unflavored gelatin (ratio should always be 2 parts water, 1 part gelatin). Gently swirl the water in the bowl to fully incorporate the gelatin in the water.
  2. Let the mixture sit for couple minutes to bloom (absorb water).
  3. Once the mixture firms up, pop the bowl into the microwave for about 20 seconds (time can vary based on your microwave). The gelatin should be warm and very fluid, but not too hot!
  4. Gently stir in a few drops of gel food coloring (and/or luster dust), being sure the gelatin is fully dissolved.
  5. Partially inflate small balloons, tying a knot high up at the neck of the balloon to make it into a (somewhat) spherical shape.
  6. Cover each balloon with a thin coat of shortening. This will make it so much easier to remove the balloons later in the process.
  7. Using your fingers, gently drip each balloon into the gelatin, rolling it to cover a majority of the balloon.
  8. Be sure to cover each balloon in a thin and even coat of gelatin.
  9. Gently rest balloon (with tie side down) on a cooling rack, and repeat with each balloon.
  10. If your gelatin cools off and thickens, pop it into the microwave and heat for 10 seconds to get it back to the right consistency.
  11. I chose to dip my balloons twice, and repeated this process once I had covered each balloon in its first coat of gelatin. This ensured they were nice and strong, and colorful (probably not necessary, but I was paranoid they would shatter!)
  12. Once the balloons have sat for about 30 minutes (I found they were had started to set by this point), you can use a small fan (on a LOW SPEED) to speed up the drying process. Be VERY careful when you do this. If your fan is too strong, it will blow your bubbles right off your counter!!
  13. My bubbles dried after about 4 hours, but without a fan they will need about 12 hours to harden.
  14. Once the bubbles have hardened, use scissors to gently puncture the exposed balloon. Once it shrinks, you can easily loosen the balloon from the bubble, and remove it.
  15. If your bubbles collapse a bit during this process, don't worry! They are rather sturdy, and any indents can be popped back into place.
  16. Use sharp scissors to trim away any jagged edges around the base of the bubble. Repeat with all balloons, then carefully press into place on a buttercream cake.


This recipe makes enough gelatin to make about 20 bubbles.

As the gelatin hardens, it will shrink. This will create loud, crackling sounds. At first I was convinced my bubbles were shattering, but was relieved to realize it just meant they were firming up quickly!

These can be made several days ahead of time! I recommend making them ahead of time, as this process is rather time consuming!

  1. Hi Chelsey. If you put these on your cake and then the cake in the fridge over night do you think the balls will get gooky and gross?

    1. that’s a good question! I am not sure because I cut into this cake right after making it, but I’d recommend not adding them to the cake until the day of to be safe! The bubbles can be made in advance and sit at room temp, so i’d just wait to add them until you’re ready to transport or serve the cake <3

  2. Ok so my bubbles have been drying at least 2 hrs now with a fan I dont hear cracking does that mean I did them wrong?

    1. Haha not necessarily! as long as they eventually harden and you can remove the bubbles, it’s a success! It might just be that your layer of gelatin is thinner than mine was!

    1. i haven’t tried it, so sadly I don’t know! but if you do, please let me know if it works! I’d love to know <3

  3. Hi Chelsea. I know you had mentioned to coat the balloons in shortening in your forward about the recipe but I would also suggest adding that step in the directions in case some people don’t read it.

    1. Hi Jenelle,

      I’ve never tried vegetable oil, but I’m not sure it would work :/ I think shortening is definitely the safer way to go!

  4. Chelsea. Thank you so much for the recipe and guidance. Very clear and precise. I look forward to trying this. I am on a bowling team, so will make them into bowling balls

    1. Aw that is such a fun idea / way to use this recipe JoAnn!! I hope it turns out amazing, I’m sure your team will love it 🙂

  5. What size balloons did you buy? Would 5-inch ones be too big? (I don’t want to open a big package only to learn I need to return it).

    Also, can you use regular food coloring or does it have to be gel food coloring? Thank you!

    1. I bought the smallest ones I could find on amazon! they were like water balloons, quite small! I highly recommend gel food coloring to make sure you get a solid color and that you don’t throw off the consistency of the gelatin. Hope that helps Sarah!

  6. I just wanted to ask if we place the bubbles onto a fondant cake and place it in a box in the fridge will that still be not ok ?thank you

    1. Hi Nicoletta! I think it would be best to not at them to the cake until the day you plan to eat it! I haven’t tested the bubbles in the fridge, but i’m worried it could cause condensation which might soften the gelatin and cause them to lose their shape :/

  7. Hi Chelsea! I was wondering if you could decorate them with royal icing or fondant? Or will it add moisture to the gelatin and cause it to soften?

    1. Hi Christine! I’ve never added anything to gelatin bubbles other an a dusting or edible glitter, so sadly I’m not sure! However, I do feel like fondant or royal icing might cause them to soften / lose their structure!

  8. Love the balloons, I made some also, I’m not going to lie, they aren’t that easy to coat evenly. But my cake turned out great!

    1. So happy you made gelatin balloons/that your cake turned out great Kathy! It can be hard to get them evenly coated, but I think it gets easier the more you do it! I also trimmed away some parts where it was uneven near the base of the balloon, which helped them look more uniform 🙂

  9. I’m norwegian and I need some help. Shortening? Whats that?! Google translate says it’s abbreviate… and thats not anything i can put on my ballons!! ? Can you use another word for shortening?! I understand it’s a white powder, but which one??

    1. It’s solidified fat! But crisco is a vegetable product. Shortening is any fat that is a solid at room temperature and used to make crumbly pastry and other food products. Although butter is solid at room temperature and is frequently used in making pastry, the term “shortening” seldom refers to butter, but is more closely related to margarine! <3

  10. I made these today using your recipe and instructions, but added some super strength cherry flavouring just to make the smell pleasant. They turned out beautifully! Thank you!

  11. It’s tricky to explain but when you get the pointy oblong bit on the top of your balloon, if you twist this bit and then pull it round and tie it to the tie knot of your balloon, it will create a perfect circular ball shape. I can find a video if that makes no sense!

    1. I’ve never thought of doing that!! I totally have to try that next time I make these 🙂 Thank you for sharing Rachel!!

    1. I would add not add any gel food coloring to the gelatin, then dust them with edible gold luster dust! You could also paint them with an airbrush with gold paint. Hope that helps, and that your Mom’s bday cake turns out great!!

    1. I haven’t tested these out on a mirror glaze, so sadly I’m not sure!! I would say adding them as close to when you plan to serve them is probably safest <3

  12. Hi! This looks so fun! I’m baking a circus themed cake for a July birthday and, I’m think these would be really cool on it. Can you tell me if there is a way to make the gelatin bubbles taste good? I’m thinking flavored gelatin but, with the shortening I’m not sure. Kids will be eating the cake and I’m pretty sure they’ll be eating every decorating I put on it. So, I want to make sure it all taste good. I was think isomaly bubbles but, I don’t have the parents to do those.

  13. I added pink dust in my gelatin before it bloomed and then into microwave for 15 sec and myne came out perfect

Let me know what you think!
