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, then smash it up into pieces. You can make larger pieces, or crush it up small, so it looks more like traditional rock candy. Really easy either way!

This easy recipe shows you how to make rock candy sheets in about 20 minutes. It’s a fast way to make it, and you can make any color or flavor with this method.
Here’s a quick overview (check the recipe card for full details):

Making Rock Candy (Top Tips!)
Here are some helpful tips on how to make rock candy at home.
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 hard 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 homemade 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 them, and they won’t stick!
How to store hard candy
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 (really only) way to make sure it gets hot enough is to use a candy thermometer to check.
This was such a fun recipe to make! I can’t wait to make different colors and flavors for holiday parties, and it will definitely be a fun thing to make for kids’ parties.
