Honeycomb candy is one of those magical confections that feels like a science experiment and dessert combined. With just a few simple ingredients, you can create an airy, crunchy candy that shatters into golden, caramelized pieces. Whether you eat it plain or dip it in chocolate, honeycomb is an irresistibly sweet and melt-in-your-mouth treat.
If you’ve ever had Crunchie Bars or Violet Crumbles, you’re already familiar with the delightful contrast between the brittle yet airy texture and the deep caramel flavor. Luckily, making honeycomb at home is easier than you think. With just sugar, corn syrup, vinegar, and baking soda, you can create this classic candy from scratch—no fancy equipment required.
This guide will walk you through everything you need to know about making perfect honeycomb candy, from ingredients to troubleshooting and creative ways to enjoy it.
What is Honeycomb Candy?
Honeycomb candy—also known as sponge toffee, seafoam candy, or cinder toffee—gets its name from its airy, bubbled interior, which resembles a honeycomb. Despite the name, there’s no actual honey in it; instead, the rich caramelized sugar combined with baking soda creates a light, crisp texture that snaps when you break it apart.
The signature air pockets in honeycomb are created when baking soda is added to hot sugar syrup. The reaction causes the mixture to foam up dramatically, trapping tiny bubbles of air inside. Once cooled, it hardens into a brittle yet delicate candy that melts in your mouth.

Ingredients for Honeycomb Candy
This recipe only requires five simple ingredients, plus chocolate if you want to coat the pieces.
- 1 cup white sugar – The base of the candy.
- 1 cup dark corn syrup – Prevents crystallization and adds a rich caramel flavor.
- 1 tablespoon white vinegar – Helps break down sugar and create a lighter texture.
- 1 tablespoon baking soda – The key ingredient that makes the candy bubble and expand.
- 10 ounces chocolate melting wafers (optional) – If you want to dip the honeycomb in chocolate.
Step-by-Step Instructions
Step 1: Prepare Your Pan
Before you start, line an 8×8-inch square baking dish with nonstick foil or parchment paper. This will make it easier to remove the candy later.
Step 2: Heat the Sugar Mixture
In a heavy-bottomed saucepan, combine:
✔ Sugar
✔ Corn syrup
✔ Vinegar
Set the pan over medium heat, stirring gently until the sugar completely dissolves.
Step 3: Bring to 300°F (Hard-Crack Stage)
- Once the sugar is fully dissolved, stop stirring and let the mixture come to a boil.
- Use a candy thermometer to monitor the temperature closely.
- When the temperature reaches 300°F (hard-crack stage), remove the pan from heat immediately.
💡 Pro Tip: If you don’t have a candy thermometer, you can test the syrup by dropping a small amount into a bowl of cold water—it should harden into a brittle thread that snaps when bent.
Step 4: Add Baking Soda (The Fun Part!)
- Quickly whisk in the baking soda—this is where the magic happens!
- The mixture will foam up and expand rapidly. Be careful, as it is extremely hot.
DO NOT stir too much after adding the baking soda, as it can deflate the bubbles that create the airy texture.
Step 5: Pour and Let It Set
- Immediately pour the foamy mixture into the prepared pan.
- Let it spread and settle naturally—don’t shake or tap the pan.
- Allow it to cool at room temperature for about 2 hours.
Step 6: Break Into Pieces
- Once completely hardened, lift the honeycomb candy from the pan.
- Use a sharp knife or your hands to break it into 1-inch chunks.
💡 Pro Tip: Honeycomb candy is delicate—avoid handling it too much or exposing it to moisture, which can make it sticky.
Optional: Chocolate Coating
Dipping honeycomb in melted chocolate makes it even better!
- Melt chocolate wafers in the microwave or over a double boiler.
- Dip each honeycomb piece into the melted chocolate, coating one or both sides.
- Place on parchment paper and let the chocolate set completely before serving.
How to Store Honeycomb Candy
Honeycomb candy is best enjoyed fresh, but you can store it for later:
- Airtight container – Keep at room temperature for up to 2 weeks.
- Avoid moisture – Humidity will make honeycomb candy sticky and chewy.
- Chocolate coating helps – If dipped in chocolate, it will last longer since the chocolate protects it from air and moisture.
🚫 Do not refrigerate – This can cause it to absorb moisture and lose its crispness.
Troubleshooting & Tips for Success
🔹 Why did my honeycomb collapse?
- Overmixing after adding baking soda can deflate the air bubbles. Stir gently and pour immediately.
🔹 Why is my honeycomb too soft?
- The sugar mixture wasn’t heated to exactly 300°F. Be sure to use a candy thermometer for accuracy.
🔹 Why is my honeycomb sticky?
- Humidity or improper storage can make it sticky. Always store in an airtight container away from moisture.
🔹 Can I use honey instead of corn syrup?
- No, honey reacts differently in candy-making and can result in burnt or chewy honeycomb.
