Edible Sugar Glass Recipe | How to make Sugar Glass (2024)

Jump to Recipe

I promise you will have so much fun with this edible sugar glass recipe. It looks like glass, behaves like glass, but it is candy!

Have you ever seen a movie where a piece of glass was broken over someone’s head? Or maybe it was a beer bottle or another kind of bottle that was broken? Or maybe you saw a person put glass in their mouth and they started chewing it? Chances are it was edible sugar glass. Are you a fan of the TV show Breaking Bad? Blue sugar glass or rock candy was used in that! It is so fun to make and the recipe is easy. You can make all kinds of things with it, movie props, bottles, a variety of candy shapes, or make an edible stained glass window held together with royal icing. You get the idea. If I can do it, you can do it. Let’s get started!

Step 1: Gather the ingredients and tools

In order to make edible sugar glass, you just need a few everyday household ingredients. No fancy ingredients are needed. You will need the following:

• White granulated sugar – Sugar is the main ingredient in sugar glass? Imagine that.
• Corn syrup – Liquid Glucose or corn syrup is used to help keep the sugar from becoming crystals again. It will help to make it more stable.
• Water
• Cream of tartar – this is an optional ingredient. But helps turn the sugar into fructose and glucose.
• Food coloring – You will need food coloring to get your desired color or colors
• Flavored Extracts – There are all kinds of flavored extracts that you can use.

Tools

• bowl
• pot or deep skillet
• wooden or silicone spoon
• sheet pan
• kitchen spray or asilicone mat
• candy thermometer (optional)

Step 2: How to make edible sugar glass

To begin, place water, sugar, corn syrup (liquid glucose), and cream of tartar in your pot or deep skillet. While the sugar doesn’t bubble up too high it is always a good idea to have something deep enough. A medium-sized pot works fine for this amount. But I generally just used my dutch oven or my stainless steel skillet.

Step 3: Prepping the pan

Next prepare the pan that you are going to put the hot liquid sugar “syrup” in once it is ready. I use a sheet pan lined with a silicone mat. Or I just spray the pan lightly with kitchen spray. While I do love my silicone mat it will have a texture to that side of it. You can also use something like shortening on your pan.

Step 4: Stirring and heating the sugar

Now place the pot on the stovetop. With the heat set to medium-low gently stir the mixture until it starts to boil. It is important to not heat it up too quickly because the sugar is liable to caramelize. Which if you are making a dark glass it won’t matter. The goal is to heat the sugar mixture to the “hard crack” stage which is around 290 to 300 F (145 to 150 C). If you are using a candy thermometer make sure it still registers the correct heat. My thermometer is old and is several degrees off so I generally just eyeball it.

Once the sugar starts to boil you can stop stirring and just let it sit for 10 to 15 more minutes. Right, when the mixture starts to turn slightly yellow it is ready to go. Another way to tell is to drop a spoonful of it into a bowl with ice-cold water. It will instantly harden up and you can check out easily it breaks.

Don’t be alarmed if it takes awhile. This whole process takes somewhere between 30 and 45 minutes. Here is an example of what it will look like if you let it boil too long or too quickly. It will be a nice amber color. But you can still definitely use it at this phase.

Step 5: Remove the boiling sugar

Once you get the boiling sugar to the proper temperature, remove it from the heat. Then add in your food coloring and any flavored extracts that you want to use. Stir them in really well. The sugar cools quickly and thickens up quickly so you need to work fairly fast.

But BE CAREFUL this sugar syrup is extremely hot and will burn you if you touch it. If you are a young person please make sure you have adult supervision when making this.

Step 6: Pour and wait

Next, pour the hot sugar onto your prepared pan. If you want to make a pane of glass that will break when someone punches it or to hit someone over the head with it, make sure to pour it thin. Spread it out if necessary. Make sure the pan is level as well. Then wait until it hardens up. It usually takes an hour or two.

An optional step would be to pour the hot sugar into silicone molds. I have made some sugar glass lego men which were awesome! If you are going to go that route I recommend making a smaller batch and using a smaller pot, it will just make it easier to get into the mold.

Step 7: Check out your awesome edible sugar glass

Once your edible sugar glass has cooled it is ready to play with. It looks like glass, it behaves like glass, breaks like glass, but it is definitely candy! Oh and more thing it is sharp like glass! So be careful. Use a mallet or something to crack that glass.

Step 8: Breaking Bad blue edible sugar glass and others

Any Breaking Bad fans? Instead of using the candy thermometer I took this batch off the stove right when it barely started to turn color. The blue food coloring worked perfectly. Doesn’t this look awesome?

Or if you don’t want to color it at all you can leave it as is and get a nice clear glass.

What if I burn my sugar can I still use it?

Yes! If you happen to walk away and come back and find that your sugar has gone beyond that hard crack phase and it looks burnt and smells burnt. You can still use it!

How do I store sugar glass?

Generally, it is best to use it within a few hours if it is in sheets. Because it can tend to warp as time goes on. I normally will just put the pieces in a ziplock bag and put them in my pantry. They can stick to each other though.

How does sugar glass taste?

Sugar glass tastes very similar to a jolly rancher if you have ever tried one of those, depending on the flavor used. It melts very easily in your mouth. Homemade lollipops anyone?

   Is the stuff thick or thin?

   • Matt Taylor

     December 12, 2023 at 9:10 am·Reply

     It can be either depending on what you pour it on, and how hot it is when it is poured. It can be spread out to me thinner or put in a smaller container and be thicker.

   Using this recipe for some Halloween treats and some scary special effects in a video! Any tips on getting it off the pot after you’re done?

   • Matt Taylor

     October 31, 2023 at 12:20 pm·Reply

     Awesome! Have fun! Yes, fill it about half way with water and heat the water up and it will dissolve any sugar on the sides of the pot. 🙂 Let me know how it turns out!

   I plan on making this today. Question about the 1/2 c. – 1 c water – how do I know if I need more than 1/2 a cup?

     Hi! The amount just means it doesn’t need to be exact so any amount between 1/2 c and 1 cup will do. 🙂 Let me know how it turns out!

   Can I make this in advance? Will it store well for a week?

   • Matt Taylor

     October 24, 2023 at 2:51 pm·Reply

     It doesn’t store super well it starts to warp, after awhile, but you can make it ahead of time and store it in plastic bags but in a single layer, otherwise they will stick to each other.

   If I add the sugar glass on the top of a cupcake and put it in the fridge will anything happen to the sugar?

   • Matt Taylor

     October 21, 2023 at 4:55 pm·Reply

     In the fridge the sugar glass will get sticky because of the moisture. Better to store it in a dry place. If possible make it at the end and place it on the cake within a few hours of wanting to serve the cake. Otherwise it is better to store the sugar glass and cake at room temp for a day or two if you need to make it ahead of time. Great question!

   How far in advance can you make these to be a cake topper please?

   • Matt Taylor

     Hello it depends on how humid the room is. They will warm a bit after time. But a few days in advance is still okay.

    I used the recipe and made some Halloween candy. The only thing is there are so many pits on the mold side of the candy. I wonder why

      Awesome! Glad you tried it. What kind of mold were you using?

    Hi, great tutorials! Is this recipe the same for pulling sugar. I’ve been looking at tutorials for both and wondered if the recipe and method was the same apart from when it’s ready to work with?
    Thanks!

    • Matt Taylor

      July 14, 2023 at 8:20 am·Reply

      Thank you! Yes pretty close a lot of pulled sugar recipes have vinegar added. Just sugar, vinegar, and water.

        What can I substitute for corn syrup ?

        • Matt Taylor

          July 18, 2023 at 7:48 am·Reply

          Golden syrup, or you can leave it out, it will still work.

    I like to make my own fruit or cherry maderia cake. The ones I have purchased from the store have lovely sugar crystals on them, if I use your rock sugar recipe ( I assume that will give me the same effect ) when would you add them to the top of my cake?.? I was thinking at the beginning when it’s still a batter, but then again I do not want them to sink into the batter or burn ?? Also having never made the crystals before what flavours do you add I am just wondering what flavour you would suggest for a cherry maderia cake? I was thinking vanilla bean paste for the currant / sultan a cake ?? But how much do I use ?? And at what stage would I add the flavour? Help I am a real novice when it comes to baking. Thank you, Victoria.

      Hi there Victoria. Have you made the cake on its own yet? If not, please do that first, so you know how to make the actual cake. You would add them to the cake after it has been baked and cooled. Not on top of the batter, it will melt the sugar glass. Just use it as decoration on top. You can add any hard candy flavoring to it. Here on Amazon you will get an idea. https://amzn.to/3oJA28Q The easiest thing would be to get Jolly Ranchers and just smash them. Then you wouldn’t need to make this sugar glass. Can you find Jolly Ranchers where you live? They are just small individually wrapped hard candy. Extremely popular in the States.

    Awesome recipe – I love how it hardens so quickly , and was even able to pull off some of the drippings left in the pot for “icy melt look”!
    I do have a question though:
    With my first batch, I didn’t use a thermometer and of course pulled it off too early and it didn’t harden (my fault – my second batch I had a thermometer and boy did that work out well!); any chance I can fix this liquid mess I now have? 😂 like would reheating and waiting until it reached temperature properly work?

    • Matt Taylor

      Thank you, Eva!! Yes, you definitely can fix it. Just reheat it to the proper temperature. 🙂
