I thought I’d share a homemade sponge candy recipe, because if your peeps are anything like mine the homemade gift they really want is something super yummy they can eat.  Sponge toffee goes by lots of different names.  It’s sometimes called honeycomb toffee, hokey pokey, puff candy, buffalo sponge candy, seafoam candy, cinder toffee, or angel food candy.  Most of the names come from the unique texture of the candy.  It’s a crunchy toffee but also an airy candy, because the toffee is full of bubbles.  It’s sticky and crunchy but also has an airy texture.  This delicious candy is made from simple ingredients and is the perfect treat for gift giving.  Serve it as is, add a sprinkle of fleur de sel, or dip it in melted chocolate and package it in a beautiful bag or tin as a gift.

My First Attempt At Sponge Candy

I’ve never made a sponge candy recipe before, but broke out my trusty candy thermometer and decided to give it a try for the first time.  As with any candy recipe, the directions are really specific.  It’s science after all, so no “a little bit of this, a little bit of that”  it’s more like a controlled chemistry experiment.

It was all going so well.  I made the candy after much research and followed all “the rules”:  300 degrees, no stirring after the sugar is dissolved, add in the baking soda but don’t over stir.  I tasted a tiny little bit I’d put aside as a tester and thought it was perfect.

The candy takes a couple of hours to set, so after it was finally ready I tried a little of the edge, it was so, so good.  Sweet, crispy, lots of bubbles -exactly what we were going for.

So, since the candy was for this blog post and I needed to get a photo in for the collage I set about dipping it in chocolate, setting up a picture, and working away.  As I worked away, I just might have nibbled away.  And as I nibbled the burnt taste of caramelized sugar gone too far became more and more pronounced.  I burnt it.

But, hey it was my first attempt.  Try, try again.

Sponge Candy Attempt Number Two -Practise Makes Perfect

I had to run some errands so when I got home that night I attempted another batch.  This time I was super careful about the sugar -because it’s tricky to get it to 300 degrees (hard crack stage) without burning the sugar first.  And you have to get it up to 300 so that the toffee will set properly and be crispy.  The second time I turned the heat down a little and watched it like a hawk.  I even calibrated my thermometer.  I couldn’t recommend a recipe to you on the blog that didn’t work, so I had to figure this thing out.

Second batch and the mixture was still mostly clear by the time it got to 300, and tuned a little amber with the addition of the baking soda, just like my research told me it should and definitely not burnt this time.

But…you knew there was a but coming, it didn’t foam up like the first batch.

Sponge Candy Attempt Number Three -Third Time’s A Charm

So, the next day when I got home that night I attempted batch number three.  It came out pretty much the same as the first batch.  Nice big bubbles and burnt.

I had the ingredients to do one more batch, so it was back to try, try again.

Sponge Candy Attempt Number Four -Last But Not Least

Batch number four I again cooked at a much lower heat, and again succeeded in not burning it, but again not as big of bubbles.

Here’s a side by side comparison, with the over done, slightly burnt batch on the left, and the better one on the right.

What Am I Doing?  The Doubting Stage

After attempt number four I was starting to doubt myself.  In fact I was thinking that after one full bottle of corn syrup and a bag of sugar that I should really be writing to you to save your time, and effort and invest the money for my four batches into a few Crunchie chocolate bars from the store -and if necessary rough them up a little, break them into pieces, tuck them into a cello bag with some ribbon and try to pass them off as your own to your friends and family.


Friends Taste Test

I brought my attempts over to some friends and they loved it -batches two and four that is.  They all really, really liked it, and declared it a win rather than a fail.  So you see it only takes one bottle of corn syrup, one bag of white sugar, and eight hours to make a lovely Christmas treat for your loved ones -haha.

What I Learned About Making Sponge Candy

Seriously though, just turn down to a medium heat after the sugar is dissolved and you’ll be fine -perhaps there’s a life lesson here for someone like me who’s always in a hurry, got a speeding ticket recently, and only cooks on high most of the time.  Patience is a virtue.

Sponge Candy

sponge candy recipe
Cook Time 20 minutes
Additional Time 2 hours
Total Time 2 hours 20 minutes


  • 2 1/2 cups white sugar
  • 1/3 cup water
  • 2/3 cup white corn syrup (it's important to use white)
  • 4 tsp baking soda (make sure it's fresh)
  • Optional -melted chocolate for dipping


    1. Measure and sift the baking soda into a small bowl and set aside. Line a 9x13 baking dish with parchment paper and spray with cooking oil, and set aside.
    2. Combine sugar, water, and corn syrup in a very large saucepan. (When you add the baking soda at the end, the mixture will increase in volume and be very, very hot so a large pan is essential to keep it from overflowing.)
    3. Cook over a high heat, and use a wooden spoon to stir the mixture until the sugar dissolves fully.
    4. Reduce the heat to medium-low and stop stirring the mixture. Occasionally brush down the sides of the pan with a pastry brush dipped in cold water to keep the mixture from crystallizing. Clip a candy thermometer to the side of the pan, and cook until it just reaches 300 degrees F or hard crack stage. Be careful not to burn the sugar, if it starts to turn amber coloured at all, turn the heat down.
    5. When it comes to 300 degrees F, remove it from the heat and stir in the baking soda until just combined. Be careful not to over stir and deflate the mixture. The candy will have a chemical reaction, and foam up creating wonderful bubbles. Pour the hot candy into the prepared baking dish -taking care as it's very, very hot. Do not smooth it out, or push down the mixture with the spoon as it will deflate it and push all the air bubbles out.
    6. Let set for about two hours at room temperature, until the candy cools and is hard. Remove from the baking dish, and use a sharp knife to break the candy into large pieces.
    7. Optional -dip the candy into melted dark chocolate or milk chocolate.
    8. Be sure to store the candy in a sealed airtight container, it should last for several days to a week.

More Options

This homemade candy is delicious on its own, but you can also dip it into melted chocolate, if you’re a chocolate lover.  We dipped some of ours into milk chocolate, but semi sweet chocolate or dark chocolate are also a great choice.  Once the candy is set and you break it into bite-sized pieces, just dip them into the melted chocolate and let it set on parchment paper.

If you’re a big fan of the salty sweet candy combination, and love salted caramel, you can also add some sea salt to your sponge toffee.  When your making it, after you have it in your baking pan, but before it sets, sprinkle the toffee with a little sea salt on top.

We made our sponge toffee for gift giving, and broke it into bite sized pieces, but it’s also a great ice cream topping.  Break it up into quite small pieces and sprinkle over top of ice cream, for a great chewy, crunchy addition.

With a homemade old fashioned sponge candy recipe, life really is a party!

  1. I always burn the sugar too!!! Always rushing to get things done and it turns out badly. I make Almond Roca every year and inevitably burn at least one batch.

    Sponge toffee makes me think of my childhood! Thanks for the recipe.

  2. HaHa… too funny! I’m one of those strange birds that probably would have LOVED your “burnt” ones. Oh my, they look so lovely and I can totally relate… everything cooked on high is my motto! That scale, I think we could be IRL picking buddies! Swooning, from the yummy treat photos and that SCALE! <3

  3. Haha Danyelle, you’re awesome, and I’m glad you persevered! It really does sound delicious, and anything dipped in chocolate is a win in my books. Candy thermometer is on my bucket list of things to buy… I keep thinking I’ll try some candy without one, but maybe not…

  4. It kind of broke my heart a little to throw out the burnt version…at least there was lots of the the good batches too. 😉

  5. Definately pick up a candy thermometer, they’re cheap and handy…you know so you’re ready when ever the candy making urge strikes, haha.

  6. I used love sponge toffee as a child. I had no idea what the ingredients were. I am sure that your successful batches were much tastier than the store bought version. What a creative idea for a homemade candy gift!

  7. i make English butter toffee every year from my grandma’s recipe she brought from Canada. this will make a great addition to the holiday tins!!
    any peanut brittle recipes??

  8. I love the English butter toffee too! There’s a recipe here for that, search under “Christmas Candy”, also a great little brittle recipe -I used Cashews and Coconut, but you switch it out for peanuts. So good…just search in the sidebar and enjoy!

  9. i have never heard of sponge toffee before! Putting this on my list of holiday goodies. Thank you for posting!

  10. Batch number one looks identical to every piece I have ever bought in Quebec! Coming from there, I know of what I speak. The “burnt” taste is right for sponge toffee, as are the large holes.

  11. I know it’s been years once you made this post but I wanted to come back here to tell you that your recipe is the one closest to a Crunchie bar that I’ve found. So thank you. I made your recipe last year to rave reviews and then couldn’t find it again. I tried two different recipes today and neither of them was right. Of course I found yours again after the second batch had set up. Sigh. I’m out of sugar and corn syrup for another batch so the first batch (the more successful of the two) will have to do. I’ve now bookmarked this page AND printed out a copy of the recipe! Thank you for sharing this recipe, your experiment in heating the sugar (super helpful), and for keeping this website going so disorganized Christmas bakers like myself can find it!

  12. Hi Elyne, thanks so much for your feedback. I’m so glad the recipe worked out well for you! If you didn’t get a chance to review the recipe with how many stars you would give it, I would really appreciate it. Just click on the stars in the recipe card underneath the image.
    Thanks again,
