A nostalgic treat with a glossy finish and crisp texture, Crystal Clear Hard Candy brings back the charm of old-fashioned sweets — with a personal twist. I like making these because I can play with colors and flavors to match any occasion, whether it’s the holidays, birthday party favors, or just something to satisfy my sweet tooth. This easy DIY candy is not only beautiful but also customizable and kid-friendly, making it perfect for edible gifts or festive table decor.
Ingredients
(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)
1 cup granulated sugar
⅓ cup water
⅓ cup clear corn syrup
≈40–45 drops food coloring (liquid works best; adjust for color intensity)
½–¾ teaspoon flavoring extract (peppermint, vanilla, fruit, etc.) or ¼ teaspoon flavor oil
Powdered sugar or cornstarch for coating (optional)
Directions
I start by preparing a sheet pan: either sifting powdered sugar or cornstarch over it, or lining it with a greased silicone mat or greased parchment paper.
In a medium heavy-bottomed saucepan, I combine the sugar, water, and corn syrup. I stir gently until everything dissolves and nothing sticks to the bottom.
Then I bring the pan to a boil over medium heat without stirring, letting it cook until it reaches the hard crack stage (about 300°F / 149°C). I always use a candy thermometer for accuracy.
Once the temperature is right, I remove the pan from heat and let it stand for 30 seconds. Then I quickly stir in my chosen flavor and color.
I pour the hot candy mixture onto the prepared sheet and spread it evenly with an offset spatula.
If I want, I sprinkle more powdered sugar or cornstarch on top, then let the candy cool completely for about 30 minutes.
Once it’s hardened, I brush off the excess sugar and break it into bite-sized pieces using a mallet or sharp knife.
I store the candy in an airtight container at room temperature, away from humidity to keep it crisp.

Variations
I like using different flavor oils like cinnamon, lemon, or bubblegum for a fun twist.
For a winter feel, I add crushed peppermint or shape the candy into shards for a frosty look.
Sometimes I swirl two colors together while pouring to make a marbled effect.
For a touch of sparkle, I add edible glitter or a sprinkle of sanding sugar on top before it sets.
Storage/Reheating
I always store the hard candy in an airtight container at room temperature, away from humidity or heat. It keeps for several weeks if stored properly. I don’t reheat this candy, as it’s meant to be eaten in its hardened form. If pieces stick together, I toss them lightly with more powdered sugar or cornstarch to prevent clumping.
FAQs
How do I know when the candy has reached the hard crack stage?
I use a candy thermometer and wait until the mixture reaches 300°F (149°C). That ensures the candy will harden properly once cooled.
Can I make this without corn syrup?
Corn syrup helps prevent crystallization and gives the candy its smooth texture. I don’t recommend skipping it, but glucose syrup can work as a substitute.
What kind of flavoring should I use?
I use either extract (like peppermint or vanilla) or candy flavoring oil for more intense flavor. Oils are more concentrated, so I use less.
Why is my candy sticky?
Humidity or not cooking the mixture to the correct temperature can make the candy sticky. I store mine in a dry place and make sure to reach 300°F.
Can I pour the candy into molds?
Yes, I sometimes use silicone candy molds for fun shapes. I work quickly when pouring, as the candy sets fast once it starts to cool.
Conclusion
Crystal Clear Hard Candy is a beautiful, nostalgic treat that I love making for holidays and special occasions — or just to have on hand when I want something sweet and crunchy. With customizable flavors and colors, it’s a fun project that looks impressive but is surprisingly easy. Once I made it the first time, it became a go-to recipe I come back to again and again.
