Ingredients You’ll Need
This Cinnamon Rock Candy Recipe calls for just a handful of ingredients, each playing a vital role to achieve the perfect texture, color, and flavor. From sugar’s crystalline crunch to the vibrant red food coloring and aromatic cinnamon oil, everything comes together to create a show-stopping candy treat.
- Water: Acts as the solvent to dissolve the sugar and corn syrup evenly, ensuring a smooth cooking process.
- Sugar: The heart of the candy, creating that crisp, glass-like brittle texture everyone loves.
- Light corn syrup: Prevents crystallization and gives the candy a lovely sheen and chewiness at the edges.
- Red food coloring: Adds a festive, eye-catching color that makes the candy as beautiful as it is tasty.
- Cinnamon oil: The star ingredient, bringing an intense, warm spiciness that elevates the candy beyond ordinary sweetness.
- Powdered sugar: Used to dust and finish the candy, preventing stickiness and adding a delicate matte finish.
- Butter: For greasing the pan thoroughly, ensuring your candy releases perfectly after cooling.
How to Make Cinnamon Rock Candy Recipe
Step 1: Prepare the Pan
The first step sets you up for success. Butter a 15x10x1-inch sheet cake pan generously, then line it with parchment paper and butter the paper again. This double layer of greasing prevents your candy from sticking and makes it super easy to lift out once hardened. Taking this extra care ensures those perfect, smooth candy edges you’ll be proud of.
Step 2: Make the Candy Base
In a large saucepan, combine water, sugar, light corn syrup, and red food coloring. Stir over medium-high heat just until the sugar begins to dissolve completely. This stage is all about gently coaxing the sugar into solution so it heats evenly without seizing, which guarantees a flawless candy texture.
Step 3: Heat to Hard Crack Stage
Attach a candy thermometer to the pan to keep a watchful eye. Bring the mixture to a rolling boil and allow it to reach exactly 300°F. This “hard crack” temperature is crucial; it’s the sweet spot where the candy will harden firmly but not become brittle in a bad way. Be patient—this can take around 20 minutes—and carefully manage the heat to avoid the syrup bubbling over your pan.
Step 4: Add Cinnamon
Once your candy base hits 300°F, remove the pan from heat immediately. Stir in 1 to 2 teaspoons of cinnamon oil quickly but cautiously, as it is intensely fragrant and potent. This infusion is how the cinnamon flavor beautifully permeates each candy crystal, giving your rock candy that irresistible spicy warmth.
Step 5: Cool and Set
Pour the hot syrup gently into your prepared pan. Let it sit undisturbed at room temperature for at least four hours. This patience rewards you with stunningly glossy, solidified candy slabs that will crack with a satisfying snap.
Step 6: Break and Dust
After cooling, dust the top generously with powdered sugar to stop any stickiness. Flip the candy slab onto a cutting board, peel off the parchment, and break it into bite-sized pieces using a knife or even your hands. Toss the pieces with more powdered sugar if you want to keep them beautifully separated and easy to handle.
Step 7: Store
Keep your cinnamon rock candy fresh by storing it in an airtight container. This will preserve the crisp texture and lively cinnamon scent until you’re ready to enjoy or share your handcrafted treat.
How to Serve Cinnamon Rock Candy Recipe

Garnishes
Cinnamon rock candy is already a star, but sprinkling a little extra cinnamon powder or pairing it with a few whole cinnamon sticks can amplify the sensory experience. These garnishes add a rustic charm and deepen the aroma when used as part of your display or serving platter.
Side Dishes
This candy pairs wonderfully with warm beverages like hot tea, coffee, or even mulled cider. The heat from these drinks slightly melts the candy, imparting a cozy cinnamon sweetness that makes each sip extra comforting. Offering small bowls of fresh fruit and nuts alongside can also balance the sweetness beautifully.
Creative Ways to Present
Turn your homemade cinnamon rock candy into charming gifts by wrapping the shards in clear cellophane tied with a cinnamon stick and a festive ribbon. You can also place the candy pieces in pretty jars as vibrant kitchen decor or use them as whimsical cocktail stirrers that add both flavor and style at your next gathering.
Make Ahead and Storage
Storing Leftovers
Store leftover rock candy in an airtight container in a cool, dry place. Proper storage keeps the candy crunchy and prevents moisture from making it sticky or soft. Avoid refrigeration, as humidity can ruin the texture.
Freezing
Freezing rock candy is not recommended. The candy’s delicate hardness and crispness can degrade in the freezer, leading to condensation when thawed, which compromises its crunch.
Reheating
Reheating is generally unnecessary since rock candy is meant to be enjoyed as a hard, crunchy treat. However, if you find it a bit too hard, warming gently near a low heat source for a few seconds can make it slightly more pliable—just be careful not to melt it.
FAQs
Can I adjust the cinnamon flavor in this Cinnamon Rock Candy Recipe?
Absolutely! Cinnamon oil is quite potent, so start with one teaspoon and increase cautiously to two teaspoons if you want a stronger kick. Just keep in mind that a little goes a long way.
Is red food coloring necessary?
While not essential, red food coloring gives your cinnamon rock candy an attractive, fiery appearance that matches the spicy flavor. You can skip it or use another color if you prefer a different look.
Can I use cinnamon powder instead of cinnamon oil?
Using cinnamon powder won’t dissolve well in the syrup and can create a gritty texture, so cinnamon oil is best for a smooth, even flavor infusion.
How long does the candy take to harden?
It typically takes about four hours to fully set at room temperature. Patience is key here to achieve the perfect solid texture.
Can I make smaller batches of this Cinnamon Rock Candy Recipe?
Yes, just halve the ingredients and use a smaller pan, but be mindful that cooking times and candy thickness might vary slightly.

Dry Ingredients
- 3 3/4 cups sugar
- 1 1/2 cups powdered sugar
Other

Instructions
- Prepare the Pan: Butter a 15x10x1-inch sheet cake pan thoroughly, line it with parchment paper, and then butter the parchment paper as well to ensure easy removal of the candy later.
