20-Minute Easy Honeycomb Toffee with Baking Soda
Crispy, airy honeycomb toffee made with sugar, honey, and a baking soda reaction that creates delicate pockets throughout. The candy reaches hard-crack stage, then the soda causes dramatic puffing for signature texture. Serve as a standalone treat, crush over ice cream, or dip in chocolate for an elegant homemade confection. This version prioritizes simplicity with no thermometer guessing-the 300F target is exact.
Ingredients
- 1 ½ cup granulated sugar
- ¼ cup honey
- ¼ cup water
- 1 tablespoon baking soda
Instructions
- 1
Line a 9x9-inch baking pan with parchment paper and coat with cooking spray.
- 2
Combine sugar, honey, and water in a large heavy pan.
- 3
Bring to a boil over medium-high heat, stirring occasionally, until darkened and reaches 300F (10 to 15 minutes).
- 4
Remove from heat and immediately stir in baking soda for no more than 5 seconds until blended.
- 5
Pour into prepared pan without spreading or moving.
- 6
Cool and set for at least 1 hour, then remove and break into bite-sized pieces.
- 7
Optional: dip pieces in melted chocolate, sprinkle with salt, and refrigerate 15 minutes to set.
Tips
Stir the baking soda very briefly (no more than 5 seconds) after removing from heat-over-mixing prevents the aeration and deflates the honeycomb structure.
Do not spread or disturb the poured mixture while cooling; movement breaks the delicate bubbles forming inside.
Good to Know
Transfer cooled toffee to an airtight container and store at room temperature for up to one week. Humidity will soften it, so avoid damp conditions.
Make up to 5 days ahead and store in an airtight container at room temperature. Add chocolate coating the day before serving for best set.
Serve at room temperature as a standalone candy, crushed over vanilla ice cream, or dipped in melted dark chocolate with fleur de sel.
Common Mistakes
Do not stir excessively after adding baking soda to avoid deflating the honeycomb bubbles.
Do not move or spread the mixture while it sets to prevent breaking the delicate structure.
Do not skip the thermometer-under 300F yields chewy toffee, over 300F turns bitter.

FAQ
Can I make this without a candy thermometer?
A thermometer ensures accuracy, but you can use the cold-water test: drop a small amount into ice water; it should crack immediately and snap cleanly at 300F. This requires practice and is less reliable than a thermometer.
What if my honeycomb didn't puff up?
Over-stirring after baking soda addition deflates bubbles. Alternatively, the mixture may not have reached a high enough temperature. Next time, stir minimally and confirm 300F before removing heat.
How long will chocolate-dipped toffee keep?
Chocolate-dipped pieces stay fresh in an airtight container at room temperature for 4-5 days. Refrigerate them in humid climates to prevent the chocolate from blooming or the toffee from softening.
