Sponge Toffee Recipe (1)

Sponge Toffee is an easy candy to make - one of the first I learned to make, as a kid - tasty, and a lot of fun to make AND eat! Try it out!

Sponge Toffee was one of my favorite treats as a kid.

We used to get it at corner stores, farmer's markets, and gas stations... or make it at home. I loved the contrast between the appearance (bubbles!), and the crispy texture.

Whether I'd let it melt in my mouth slowly, or chomp through (and pick the sugar off my teeth for a long time afterwards!), it was just a fun food to enjoy.

As I got older, I realized that gas station sponge toffee is just *no* match for homemade.

This is really easy to make, and a lot of fun for kids to watch (From a distance! Hot sugar can be dangerous!).

What is Sponge Toffee?

Sponge toffee is an easy to make candy that’s usually sold in blocks or in chunks / nuggets.

The technique used to make the candy causes it to fizz up at the last minute, and it hardens full of holes. This gives it an airy, bubbly, almost flaky texture.

How to Make Sponge Toffee

Like all caramel or toffee based candy, this one starts off by boiling sugars together with water.

As the water boils off, temperature raises, the sugar caramelizes, and the whole mixture becomes something capable of hardening into a brittle candy.

At the last minute - as soon as the mixture reaches the appropriate temperature - you quickly mix some baking soda in, which causes it to VIOLENTLY bubble up.

Be very careful with this - sugar burns are no joke! Be sure to use a long handled spoon to mix the baking soda in, keeping your hands clear of the ... volcano.

As you stir the baking soda in, you’ll want to be sure it’s well incorporated, but you’ll also want to be mindful of how much you stir / beat it.

The less you beat it, the higher it will rise, and the bigger the holes will be.

The more you beat it, the smaller the holes will be, the less lift you’ll get, and the denser the final candy will be.

Once you’ve beat it as much as you’d like, quickly pour it into a prepared 9 x 13" pan.

If you’ve been judicious in your mixing, it will continue to foam a bit in the pan - it’s good to not beat the “life” out of it, in the pot.

Then, you let it cool.

If you’d like set sizes / shapes (blocks, bars), you can score the candy with a sharp knife. DO this several minutes after pouring it into the pan, so you don’t affect the rise.

As the candy cools, gently re-establish your score cuts, bit by bit. Once it’s 100% cooled, you can easily break it into the blocks or bars you’d like.

Sponge Toffee Around the World

Growing up, it was "sponge", but some older people (looking back, probably immigrants or 1st gen Canadians from England, where "Honeycomb" is the term for it) would call it honeycomb toffee.

I always liked that - it's a much cuter / more tasty sounding name than "sponge". Who wants to eat a sponge, anyway?

When I was in Minnesota, it was called "sponge candy" the few times I saw it. It definitely wasn't as commonly available there, as it had been my whole life in Canada.

Via friends, I learned that the same stuff was referred to as "foam candy" or "seafoam" in some other places in the US.

Sponge Toffee - or something very similar - exists around the world, in slightly different variations, and with a bunch of different names.

I love that New Zealanders call it "Hokey Pokey" and put it in ice cream!

As a kid, I enjoyed drizzling ice cream with a bit of corn syrup and topping with the crumbs left over from making a batch of this toffee.

Sponge Toffee Variations

Chocolate Dipped

The most common variation you’ll see to this recipe is to dip the final - cooled - candy into chocolate.

Here in Canada, we have a popular candy bar based on this idea, the Crunchie bar. (I have a recipe for Homemade Crunchie Bars!).

Other than that, you can break up the cooled candy and dip them - fully or partially - in the melted chocolate of your choice.
Personally, I prefer milk or dark chocolate for this. While I enjoy white chocolate in general, it doesn’t taste quite right with the toffee.

Ginger Molasses

While I wouldn’t call this a common variation - I came up with it myself, years ago - you can always swap out the corn syrup and add some ginger to make Ginger Molasses Sponge Toffee!

I designed that recipe to have the taste of a gingersnap cookie, only in candy form. I love the stuff!

Sponge Toffee

Sponge Toffee is an easy candy to make - one of the first I learned to make, as a kid - and it’s also one of the first recipes I blogged. Give it a try!

Prep Time5 minutes mins

Cook Time20 minutes mins

Cooling time1 hour hr

Total Time1 hour hr 25 minutes mins

Course: Dessert, Snack

Cuisine: British

Servings: 20 - 1 9x13 pan of toffee

Calories: 130kcal

Author: Marie Porter

Equipment

  • 9 x 13 Baking Dish

  • Candy Thermometer

Ingredients

  • 2 ½ cups granulated sugar
  • cup corn syrup
  • 6 tablespoon water
  • 2 tablespoon baking soda
  • 2 teaspoon vanilla

Instructions

  • Prepare a 9″ x 13″ cake pan with nonstick spray, or a light coating of vegetable oil or shortening. Set aside.

  • In a large saucepan, stir together sugar, corn syrup, and water. Attach a candy thermometer to the pan, making sure that it does not touch the bottom of the pan.

  • Bring mixture to a boil, and allow to cook until temperature reaches 300 degrees F (hard crack stage). From the time mixture starts boiling to the time it reaches 300F, do not stir.

  • Once mixture reaches 300F, remove from heat.

  • Add vanilla and baking soda, beating to incorporate. The mixture will start foaming quite a bit when you add the baking soda (chemical reaction!), so using a LONG wooden spoon is a good idea. The sugar will be very hot, and will burn if you get any on your hand as you stir. Be very careful and work FAST.

  • Dump foaming mixture into greased cake pan, spreading it out as evenly as possible. Allow it to cool completely.

  • Once toffee is cooled all the way through, remove from pan and snap into chunks / nuggets and serve.

Notes

  • Be sure to store toffee in an airtight container – the sugar will attract water from the air, and the toffee can go soggy.
  • While you definitely want the baking soda to be fully mixed in, know that how much you beat it affects the final texture. If you beat it a lot, the air bubbles will be smaller than if you don't.
  • If you like big, airy toffee, beat it the minimum possible, and GENTLY pour it into the pan. DO NOT disturb it - it will keep rising and developing big bubbles.

    Hello, how long would the toffee be good for in an air right container at room temperature?
    Thank you.

      Probably a few weeks? We've never had it last long enough to really have an idea of longevity.

        This sounds a lot like Irish candy called Crunchies. I love it but after it’s cooled it’s dipped in chocolate. So yummy!!

    Other recipes call for vinegar. Will it work without it?

    Reply

    • Marie Porter

      I've never even heard of making it with vinegar. I've been making it with the recipe since I was a kid, and I'm assuming my grandma was making it much longer.

Sponge Toffee Recipe (2024)

FAQs

What is sponge toffee made from? ›

Honeycomb toffee, honeycomb candy, sponge toffee, cinder toffee, seafoam, or hokey pokey is a sugary toffee with a light, rigid, sponge-like texture. Its main ingredients are typically brown sugar (or corn syrup, molasses or golden syrup) and baking soda, sometimes with an acid such as vinegar.

Why is my sponge toffee chewy? ›

Chewy honeycomb happens when the mixture hasn't been cooked for long enough. This is most common when you don't use a sugar thermometer. If you don't heat the mixture to 149°C the sugar won't achieve the brittleness required for that crumbly, crunchy texture.

Why do bubbles form in sponge toffee? ›

The candies are in the toffee family. Both honeycomb and sponge candy are made by boiling sugar and a golden syrup of some kind. To get the iconic texture of either, baking soda is added. This common baking ingredient responds to the compounds in the mixture creating air bubbles of varying sizes.

Why is my toffee chewy and not crunchy? ›

Low and slow

Simmering the syrup for English toffee to the requisite 300°F temperature can (and should) be a slow process — up to 20 minutes or so. Don't hurry this gradual transformation; syrup that doesn't reach 300°F, or close to it, will make candy with timid flavor and chewy (not crunchy) texture.

Why does my sponge toffee taste burnt? ›

The trick is to avoid any clumps or pockets of soda, so stir more than you think you should - a whisk works well. It's the areas with too much soda that get the big bubbles and the burnt taste. The warmed oven really helps with keeping the loft in the candy.

Why do you put baking soda in toffee? ›

You might wonder why the toffee recipe includes baking soda. It is added at the end of the boiling stage and creates lots and lots of bubbles. These bubbles help to lighten the texture of the finished toffee, resulting in an easier-to-bite candy.

Why is my toffee not set and why is it's texture grainy and not smooth? ›

As the toffee cools and the molten sugar crystals become solid again, they are attracted to the 'seed' forming new lumps of tiny crystals – hence the grainy texture. This can also happen if the toffee is stirred, or agitated, after it has begun to boil or on cooling (as happened with this pink-tinted toffee).

Is chewy toffee the same as caramel? ›

This overview aims to clarify their differences. While they share a golden-brown colour and a sugary base, toffee and caramel are distinct in ingredients, preparation, and texture. Toffee, known for its hard and brittle nature, contrasts with caramel's soft, chewy consistency.

Should toffee be hard or soft? ›

Toffee is a hard candy made by cooking a sugar syrup with butter to the hard crack stage, 300–310°F (149–154°C), and then pouring it out to cool. It can have inclusions or not, and it can be made either very dense and hard or can be lightened by adding baking soda when the candy is almost done cooking .

Who invented sponge toffee? ›

Science has discovered many answers, but there are still many mysteries that remain unsolved; Bigfoot, the Loch Ness Monster, how were the pyramids built, and of course, who invented sponge candy. Some say the British invented it first with their cinder toffee. Others might say Cadbury's Crunchie bar was the first.

Why does my homemade toffee stick to my teeth? ›

You might check the amount of water you are using. If it is more than 1/4 c. per pound, you might be inverting the sugar which would give the same effect of adding corn syrup, making it sticky.

Why add water when making toffee? ›

Adding water to sugar before caramelizing it helps it melt at a more even rate, and helps reduce the risk of crystalization. You only need to add enough water to turn the sugar into a slurry, and it all boils off as you heat the syrup.

What can go wrong when making toffee? ›

Stirring too quickly or too often can cause the toffee to separate. Moderate the heat as needed – turn it down if the toffee is boiling or cooking too fast so it doesn't burn. Cook until the toffee registers 285-290 degrees on an instant-read or candy thermometer and is deep amber brown in color, about 20-25 minutes.

How do you know when toffee is done? ›

Once boiling, cook, stirring only 2 to 3 times, until it turns a dark amber color and the temperature reaches 285 degrees F (137 degrees C) on a candy thermometer, 20 to 30 minutes.

What happens if you cook toffee too long? ›

Toffee Making Tips + Troubleshooting

Your toffee is better off overcooked than undercooked! Undercooked toffee won't be anything more than a caramel sauce. But overcooked toffee will be just slightly crunchier (almost unrecognizably). So, always err on the side of over-cooking!

What is the inside of sponge candy made of? ›

Sponge candy is made from a few simple ingredients. Sugar, corn syrup, water, vinegar, and baking soda are what create the magical filling of sponge candy. Traditional toffee is hard, brittle, and buttery, but the secret to sponge candy is air.

What is sponge candy from Buffalo? ›

Sponge Candy is a light and crunchy but delicate toffee made from sugar, corn syrup, and baking soda. The recipe is very simple but produces a very unique flavor reminiscent of toasted molasses.

Is sponge candy the same as seafoam candy? ›

Seafoam candy is a vintage treat that gets its name from its signature airy and bubbly appearance. This confection goes by several other names as well, depending on your region. Some call it sponge candy, honeycomb, hokey pokey, fairy food, or cinder toffee.

Does sponge toffee have dairy? ›

Ingredients: Milk Chocolate (sugar, cocoa butter, skim milk powder, cocoa mass, whey powder, lactose, butter oil, soya lecithin, natural flavour), Sugars (sugar, glucose syrup [wheat]), Sodium Bicarbonate, Gum Arabic, Shellac. May contain: Peanuts, Tree Nuts.
