Note: During the entire cooking process be very careful not to get any of the sugar mixture on your hands. The mixture will be very hot. I recommend wearing oven mitts during the cooking process to be extra safe.

1 Line a rectangular 9 x 13 baking dish with parchment paper to cover the base of the pan and high enough to go above the edges of the pan.

2 In a medium sized pot stir together the sugar, honey and water with a metal whisk or fork.

3 Heat on medium heat for 12-15 minutes until everything fully melts and started to bubble.

4 Once the mixture has turned amber in color, add in the baking soda and stir vigorously. The mixture will being to foam up, bubble, and double – triple in size. Turn the heat off.

5 Using a rubber spatula pour the mixture into the lined baking dish.
Note: the mixture will flatten and spread throughout the baking dish on it’s own. Do not use a utensil to spread the mixture out. If you try to spread it out with a utensil it will cause holes and gaps. Do NOT use hands to spread mixture, it will burn you!

6 Leave the sponge toffee at room temperature to set for 2 hours. Once it has hardened break into smaller pieces.

Tips for the Best Sponge Toffee

  • Ingredients – this recipe cannot have any ingredients swapped. The ratio of water, sugar, honey and baking soda is specific to this recipe and therefore no substitutions can be made.
  • Prep – be extremely careful during the entire cooking process. I wear oven mitts once I start heating the water, sugar and honey mixture. The candy is extremely hot and will instantly burn your skin if it comes in contact with skin.
  • Setting Time – before you star to make the sponge toffee line a baking sheet with edges with parchment paper. This way once the sponge toffee mixture is ready you can pour it right into the tray. Allow the sponge toffee to naturally spread out in the tray. If you try to use a spoon, spatula or anything else to spread out the toffee it will stick to it and cause holes in the toffee. Allow the sponge toffee to set at room temperature. Once it has fully set, tap it on the top to make sure it is hardened. Then break it up into pieces to serve.
