I'll never forget the first time I made cinnamon rock candy – it was a total happy accident! I'd been trying to recreate those old-fashioned cinnamon candies from my grandma's candy dish, but my first attempt turned into a sticky, spicy mess. After a few (okay, maybe more than a few) batches, I finally nailed it. The moment that fiery sweetness hit my tongue, I knew I'd struck gold. This isn't just candy – it's pure nostalgia with a kick!
What makes this cinnamon rock candy so special is that perfect balance between sweet and spicy. The sugar gives you that classic candy crunch, while the cinnamon oil delivers that warm, tingly heat that lingers just long enough to make you reach for another piece. It's easier to make than you might think, and once you taste homemade, you'll never go back to store-bought. Trust me, your kitchen will smell like Christmas morning while this candy cooks – and the results are absolutely worth it!
Why You’ll Love This Cinnamon Rock Candy Recipe

Ingredients for Cinnamon Rock Candy
Here's everything you'll need to make this fiery-sweet treat:
- Syrup Base: 1 cup water, 3 ¾ cups granulated sugar, 1 ¼ cups light corn syrup
- Flavor & Color: 1 teaspoon red food coloring, 1–2 teaspoon cinnamon oil (start with less - this stuff is strong!)
- Finishing Touch: 1 ½ cups powdered sugar for dusting, plus butter for greasing your pan
See? Simple ingredients with big flavor payoff!
Ingredient Notes & Substitutions
Cinnamon oil is non-negotiable - extracts won't pack the same punch. But careful! It's potent - I learned the hard way when I accidentally made "fire breath candy." Corn syrup prevents crystallization - honey works but makes a softer candy. For color, gel food coloring gives vibrant red, but liquid works too. And always use real butter for greasing - it gives the best release.
Equipment You’ll Need
You don't need fancy gadgets for this cinnamon rock candy - just these basics:
- A heavy-bottomed saucepan (trust me, thin pans burn sugar)
- Candy thermometer - no guessing when it hits hard crack stage!
- Buttered baking pan (I use a 9x13" but any shallow pan works)
- Airtight container for storage (moisture is candy's enemy)
That's it! Now let's make some magic.

How to Make Cinnamon Rock Candy
Ready to turn simple ingredients into that magical spicy-sweet crunch? Here's my foolproof method - just follow these steps carefully (and keep bandaids handy for any sugar burns - ouch!).
Step 1: Prepare the Pan
First things first - grab your pan and slather it with butter like you're frosting a cake! Every nook needs coverage unless you want candy glued permanently to the pan (been there).
Step 2: Cook the Sugar Syrup
This is where the magic happens! Combine water, sugar and corn syrup in your heavy saucepan. Medium heat works best - too fast and you'll burn it. Stir constantly until the sugar dissolves (about 5 minutes), then stop stirring and clip on that candy thermometer. Watch it climb to 300°F (hard crack stage) - this takes 15-20 minutes of patient waiting (no peeking!).
Step 3: Add Flavor & Color
Now the fun part! Remove from heat and quickly stir in food coloring and cinnamon oil. Warning - that oil's strong! Start with 1 teaspoon and add more if you dare. The steam will smell amazing but might make you cough - open a window!
Step 4: Cool & Break
Pour immediately into your buttered pan (careful - it's lava-hot!). Let it sit undisturbed for at least 2 hours - I know, the wait kills me too. When completely cool, whack it with a butter knife for satisfying shards. Dust with powdered sugar to tame the heat (or not - live dangerously!).
Tips for Perfect Cinnamon Rock Candy
After making countless batches (and plenty of mistakes!), here are my hard-won secrets for cinnamon rock candy success:
- No stirring after boiling - This prevents crystallization and keeps your candy clear
- Cold water test - Drop a bit in ice water to check for hard crack stage if your thermometer fails
- Light dusting - Too much powdered sugar masks that beautiful spicy kick
- Work fast - That syrup sets quickly once it's off the heat!
Remember - patience makes perfect candy. And burnt sugar smells terrible, so watch that heat!
Storing Your Homemade Cinnamon Rock Candy
Here's the secret to keeping your cinnamon rock candy crunchy and fiery for weeks - tuck those beautiful red shards into an airtight container (I love using mason jars for gift-worthy presentation). Moisture is the enemy, so skip the fridge - room temperature is perfect. If you can resist eating it all immediately, it'll stay fresh for about 2 weeks... though in my house, it never lasts that long!

Cinnamon Rock Candy FAQs
Over the years, I've gotten so many great questions about this cinnamon rock candy recipe - here are the ones I hear most often!
- Can I use cinnamon extract instead of oil? Oh honey, no! The oil is about 4 times stronger. I once tried extract and ended up with sad, barely-spicy candy. It's worth tracking down the real stuff.
- Why did my candy turn cloudy? You probably stirred it after boiling - that creates sugar crystals. Next time, resist the urge to stir once it starts bubbling!
- Help! My candy is stuck to the pan! Been there! Next time butter that pan like you're preparing for a blizzard. For now? Carefully warm the bottom over low heat to release it.
- Can kids help make this? Absolutely - but keep them far from the hot syrup! Let them help with greasing pans or dusting with powdered sugar when it's cool.
