Ingredients Breakdown
- Granulated Sugar: The base for creating those beautiful candy crystals. Don’t skimp here; regular white sugar works best.
- Light Corn Syrup: Ensures smooth texture and prevents the sugar from crystallizing prematurely.
- Water: Helps dissolve the sugar and provides the right consistency for the candy base.
- Cinnamon Oil: This is what gives the candy its signature spicy kick! Use sparingly—it’s potent.
- Red Food Coloring: Totally optional but gives the candy that iconic festive look.
- Powdered Sugar: For dusting and preventing the candy pieces from sticking together once broken into shards.
Step-by-Step Instructions
- Line a baking sheet with foil and lightly coat it with nonstick spray or butter. This is where your candy will cool and take shape.
- In a heavy-bottomed saucepan, combine 2 cups of granulated sugar, 1 cup of light corn syrup, and 1/2 cup of water. Cook over medium heat, stirring occasionally, until the sugar has completely dissolved.
- Attach a candy thermometer to the side of the pan. Increase the heat to high and allow the mixture to boil without stirring until it reaches the hard crack stage (300°F).
- Once the mixture reaches 300°F, immediately remove it from the heat. Carefully stir in 1/2 teaspoon of cinnamon oil and a few drops of red food coloring, if using. Be cautious here, as the cinnamon oil releases a strong aroma when added to the hot syrup.
- Quickly pour the hot mixture onto your prepared baking sheet, spreading it out slightly with a heatproof spatula if needed.
- Let the candy cool completely. This usually takes about 30-40 minutes.
- Once cooled, break the candy into irregular pieces using the back of a spoon or a mallet.
- Toss the broken candy pieces in powdered sugar to prevent sticking, and enjoy!

Chef’s Tips and Tricks
- Safety first: The sugar syrup gets extremely hot, so make sure to keep little ones and pets out of the kitchen while making this recipe.
- Quick cleanup: Soak your saucepan and utensils in hot water immediately after use to dissolve the hardened sugar easily.
- Adjust the spice: If you prefer a milder candy, start with 1/4 teaspoon of cinnamon oil and adjust to taste.
Recipe Variations and Serving Suggestions
- Flavors: Swap cinnamon oil for peppermint oil and green food coloring for a wintry twist.
- Gift-worthy: Package the candy pieces in mason jars or festive gift bags with a ribbon for a thoughtful homemade present.
- Party favors: Pair with hot cocoa or tea for the ultimate pairing in a goodie bag.
FAQs
- How do I store Cinnamon Rock Candy? Store the candy in an airtight container at room temperature for up to 2 weeks. Keep it away from humidity to prevent it from becoming sticky.
- My candy isn’t hardening—what went wrong? This usually happens if the syrup didn’t reach the hard crack stage. Double-check using a candy thermometer next time!
- Can I make this recipe without a candy thermometer? While a candy thermometer is highly recommended, you can test the syrup by dropping a spoonful into ice water. If it hardens into brittle threads, it’s ready.
