It’s so simple to make a sheet of this hard candy and then break it into pieces. It’s up to you: make larger pieces, or crush it up small, so it looks more like traditional rock candy.
I made blue raspberry candy (which is a great flavor and color combo), but you can choose any color or flavor you want with this rock candy recipe. Follow the same simple method, and add in your preferred flavor extract and food coloring.

How to Make Rock Candy
This easy recipe shows you how to make rock candy sheets in about an hour. It’s a fast way to make it, and you can make any color or flavor with this method.
- Mix the ingredients together, and boil to reach 300 degrees F.
- Remove from heat and let it cool just until bubbles stop breaking at the surface and pour it onto a baking sheet (lined with foil and non-stick spray).
- Once it has completely cooled and hardened (about 30-45 minutes), you can break it apart and eat!
How long does it take to make rock candy?
With this method, making rock candy takes only 20 minutes, plus cooling time (usually 30-45 minutes for it to harden).
How do you break up hard candy sheets?
- To turn the sheet of candy into small pieces, it’s easiest to use a metal mallet (like a meat tenderizer). Just hit the sheet with it until it breaks into pieces.
- If you want to make it look more like rock candy, place those pieces into a bag, and use a rolling pin to crush them up even smaller.
How do you stop Rock Candy from sticking together?
Place the candy pieces into a resealable bag, pour in some powdered sugar, and shake it up to coat the candy. Do this before storing, and they won’t stick!
The great thing about hard candy is that it really lasts! Well, assuming you don’t eat it all.
- Place the candy in an airtight container to store it. (Try the powdered sugar tip above.)
- Store it at room temperature, ideally in a pantry or cupboard where it’s slightly cooler.
- You can keep it for weeks!
Why isn’t my candy hardening?
If your candy doesn’t harden, even after sitting for a long time (it should only take 45 minutes, not much longer), it might be that your liquid never got hot enough.
It’s important that the temperature reaches 300°F while cooking the syrup. And the best way to make sure it gets hot enough is to use a candy thermometer to check. This is not the time for guessing!
This was such a fun recipe to make! I can’t wait to make different colors and flavors for holiday parties, and it will be a fun thing to make for kids’ parties.

Made this with my kiddos and they definitely enjoyed it and so did I.
So happy to hear that!
Mine hasn’t hardened after about 5 hrs. I’ve put it in the fridge. We shall see!
Oh no! I hope it works out!
Where did you find the blue raspberry flavor? I haven’t had any luck so far
It’s raspberry, just with blue dye!
Any tips on how to make this clear to make it look like ice? Mine is just a dark yellow. Super easy tho!
Light corn syrup and temperature could be the issue!
Good recipe. Would have worked but I burned the sugar too much. It did not catch fire, thank goodness. I am going to try this recipe again and again until I get it right
Good luck, Josh! I hope this next round is flawless!
The candy thermometer I got was faulty so I didn’t get it hot enough (it’s still not hardened after 11 hours), but I tasted some of the mixture and it was really good (I used lemon extract), so I’m sure this will be great if I can make it right! Lol
Thanks for sharing, Harley!
Love it. Blue peppermint!
Thanks for stopping by, Scott!
