Rock Candy
Making rock candy is surprisingly easy! I never thought I’d end up making my own candy, but this little DIY was so much fun. I wanted to make blue candy in honor of the Breaking Bad finale, and this recipe was just the thing.
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.
Making this rock candy at home is such a fun experience and it is a really cool party treat! Both kids and adults love this stuff!

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.

Becky’s tips
- TIP: I had a reader comment that a great way to keep them from sticking is shaking them in powdered sugar before sealing in an airtight container. GENIUS!
Nutrition Information
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!

I love baking and making candy I’m trying to teach my grandchildren it doesn’t have to be a an occasion make something everyday
Your grandkids will love it!
I hated the taste. It tasted burnt. Mine turned green and it was at 300 degrees but, cooled quickly and was easy.
I’m so sorry you didn’t enjoy this one!
Just made this! And it is awesome and so easy! I will actually use this rock candy as the gems in my geode cake later this week! I used lemon extract in mine and it is delicious! Thank you!!
That sounds awesome!! I’m glad you enjoyed making this!!
How much food coloring did you use? Paste or liquid? Does the color change as the syrup hardens?
Thank you for any help.
I just did the eyeball test. It should pretty much stay the same as it hardens. Enjoy!
This was super awesome I hope it hardens for me if not it’ll be great for rock candy sticks.
