Treacle fudge is a common treat in the Wizarding World, whether you are at Hagrid’s Hut or shopping at Honeydukes. Now you can make it too!
Jump to RecipeBefore I set out on my journey to make delicious foods inspired by the Harry Potter books, I had never heard of Treacle before. Upon further investigation (thanks internet) I found that it’s a type of light sweetener, similar to molasses, that’s popular in British sweets, also called golden syrup. Of course, this made finding some a bit more difficult. I had to order a bottle on Amazon (found here) to use for Treacle Fudge and the Treacle Tarts.
Treacle Fudge first appears when Rubeaus Hagrid gives it to Harry, Ron, and Hermione in The Chamber of Secrets. This is after Ron’s wand backfires and has him burping up slugs. The real thing is also sold at Honeydukes Sweetshop in the Wizarding World of Harry Potter in Orlando.
“He [Professor Lockhart] was the on’y man for the job,” said Hagrid, offering them a plate of treacle fudge, while Ron coughed squelchily into his basin.
…
“An’ then I told him [Lockhart] I’d never read one o’ his books an’ he decided ter go. Treacle fudge, Ron?” he added as Ron reappeared.-Harry Potter and the Chamber of Secrets

‘ve always enjoyed fudge, but I hadn’t made my own before trying this out. A few of the times that I went to Wizarding World in Orlando I bought fudge from Honeydukes, and it was delicious! They have so many different flavors there to choose from. It’s been years now, so I don’t remember which we bought. All I know is it was addicting!
I decided to try Treacle Fudge. This one is the only edible “fudge” mentioned in the Harry Potter series. I found a recipe here and worked with that the best I could.
I originally made my treacle fudge with regular molasses because I couldn’t find the golden syrup in stores here. We didn’t have time to order it online before I wanted to make the recipe. I have since made it with the golden syrup and it tastes even better. If you don’t have access to golden syrup, molasses will work in its place. The molasses is just closer to black treacle than it is to light treacle. The fudge will have a darker, more bitter taste with molasses than it will with golden syrup.

Treacle Fudge Step by Step
Ingredients
- 1 cup granulated sugar
- 1 cup brown sugar
- 8 tbsp unsalted butter
- 1/2 cup heavy whipping cream
- 2 tbsp treacle syrup
- 1/4 tsp cream of tartar
- 1 tsp vanilla extract

Preparation
For the treacle fudge, you are going to want to use an 8×8 baking dish. The fudge won’t be baked, but the square pan is a good size for the amount of fudge this makes. Prepare your pan by greasing it. You can also line with parchment paper for easier removal.
In a saucepan, over medium heat, add all of the ingredients EXCEPT the vanilla extract. Stir constantly until the butter melts and the sugar dissolves.

Once the fudge has melted, stop stirring and let it cook until the mixture reaches 240F on a candy thermometer which is the soft ball stage. Then remove the pan from the heat and immediately stir in the vanilla extract.

Let the fudge sit, without heat, for about 5 minutes, until the bubbles start to subside. Now for the not-so-fun part: take the candy thermometer out of the pan and stir constantly with a wooden spoon for about 15-20 minutes.
The mixture will start to lose the glossy sheen and get very thick. This is when it’s best to have someone helping so you can take turns. My arms were getting worn out!

Pour mixture into your prepared pan and smooth it out on the top using the palm of your hand. Just be careful because it may still be a little warm. You can line it with a piece of plastic wrap to keep the fudge from sticking to your hands.

After the fudge has completely cooled at room temperature, for about an hour, carefully cut it into 1-inch squares and serve!

Treacle Fudge Leftovers
Storage: Store the remaining treacle fudge in an airtight container. If you live in a warm, humid area you’ll want to keep it in the refrigerator. Otherwise, it is ok to sit out at room temperature.

I can only imagine how friggin AMAZING that made your house smell, HOT DAMN – YUM!
It smells so good. Sometimes that’s one of the best parts of cooking: when the house smells delicious all day long!
This would be the perfect treat for a Harry Potter movie marathon! I love this idea; and it’s so easy to make!
My Harry Potter club loved the recipe! It’s very sweet, but oh so yummy.
It looks so soft!! I can practically case it melting in my mouth. Great job!
And it stays soft even a couple of days later! It does basically melt in your mouth.
Nice! I didn’t realize there was actually treacle syrup. Would love to try. I made treacle tart from the book and discovered glorious golden syrup. Have you ever had that? Yummy!
Golden syrup is a form of treacle syrup. It’s the lighter version vs black treacle. I use golden syrup for my treacle recipes and it’s delicious!
That sounds totally yummy – I adore fudge! And it looks so easy to make too…
I’ve always enjoyed fudge, too, but never made it much at home. This one was so easy so it makes me think I could easily make other versions, too!
I wasn’t sure what Treacle was either! Thank goodness for Amazon. My nephew is having a Harry Potter party. Can’t wait to show him this recipe!
Seriously, I wouldn’t have been able to make these without Amazon since I can’t get golden syrup in the stores near me. Treacle fudge is perfect for a HP party dessert!
Iam loving all the Harry Potter themed food. I still don’t quite get what treacle is though.
Treacle is just a different type of syrup than maple syrup. The darker version, black treacle, is close to molasses. Golden syrup reminds me of a mix between maple syrup and honey.
They look gorgeous and so tasty! I love using brown sugar in my desserts, it gives a different sweet taste!
I could eat brown sugar by the spoonful, so it’s in a lot of my desserts, too!
Oh, this looks super yummy. I will definitely have to try this. I love trying new recipes!!
It’s always fun to try something new!
We are definitely going to make this for our next Harry Potter marathon! This looks easy enough for the kids to get involved. Thank you for satisfying my sweet tooth!
The kids can definitely help. Even though he isn’t always in the photos, my oldest son loves to help in the kitchen and makes a lot of my recipes with me.
That’s kind of cool that you ordered the treacle. I love cool things from other countries!
I do, too. I know people in a few other countries who have sent me some of their favorite treats that are only available there and I’ve sent them stuff. It’s so fun to try foods from around the world!
There’s nothing better than fudge! This recipe is much appreciated. I’ll have to make it this weekend!
I agree, fudge is such a delicious dessert! I hope you enjoy yours 🙂
I still haven’t seen any of the Harry Potter movies. So I haven’t heard of treacle either. Of course Amazon would have it LOL. The treacle fudge recipe looks amazing! I love different types of fudge so I may have to give this a try.
Oh man, you should definitely watch them! Of course, as a book lover, I will say to read the books first 😉 And yes, I love Amazon, I can find almost anything on there, no matter how obscure!
Omg….this fudge looks super soft and yummy. I loved the way you have clicked pictures at each stage of cooking. Looks delicious!
The fudge almost melts in your mouth, it’s so soft. And I am a visual learner, so I know it helps to have the step-by-step photos for many. I try to help you all with the recipe in the way I would want to learn!
I have always loved fudge! But never found a perfect recipe. Until now! I will definitely try it out this weekend! I can’t wait!
There are soooo many different ways to make fudge! I’ve tried a few recipes before, but this one is just too easy and so sweet.
Oh, I’m so glad to hear that you tried it both ways and that molasses works too! I’m trying to cut back on our special-ingredient ordering from Amazon LOL, so this is good to know that we could use up what we have first 🙂 But this looks seriously SO good. Kimmie got a Harry Potter cookbook for Xmas, so am curious to see if there is a recipe for this in there and how they compare…am betting yours will be better since yours are always SO good! 🙂
The molasses doesn’t have quite the same flavor, since it’s a bit more bitter than golden syrup, but it still works well and the first batch was gone that evening. I have a couple of HP cookbooks on my Christmas list that I didn’t get so they are rolling over to my birthday list next month 🙂
Ooh, I absolutely LOVE fudge! I’ve never made it myself though so maybe it’s time I gave it a try… I’m sure this will be much more tasty than shop bought fudge…
It was much easier than I thought it would be the first time I made fudge. It seems a lot more complicated than it really is.
HAND OVER the fudge and NO ONE gets hurt! LOL!
It’s a long trip, but you’re welcome to head to Houston and take some 😉
I love fudge and this look super yummy. I haven’t tried making with treacle syrup. So I am excited to try this.
I’ve used both molasses (which is close to dark treacle) and golden syrup and the golden treacle syrup is better. It’s sweeter so it works well with the fudge.
I just love fudge! It’s actually been a pretty long time since I’ve even had any fudge. Might just have to try your recipe
Before I made this the first time, it had been years since I had fudge, too. This was the first one I made myself and it was much easier than I thought it would be!
I am so curious about the flavor of this. Sounds so interesting and definitely isn’t something I’ve tried before. I think the biggest reason why I haven’t made fudge is the never ending stirring!
Oh my gosh, the stirring! It does seem to never end. But it’s a great arm workout!!
These are just so delicious looking! I’m definitely saving this for later! Who doesn’t love a good fudge?
It’s such a delicious fudge, and very, very sweet! It goes a long way because most people only want a small piece.
This looks so good! My son loves fudge, I will have to make this for him this weekend…YUM!!!
Oh what a great treat for your son! Fudge is so yummy, and not too hard to make, either.
In your instructions, you say let it cook until the mixture reaches 225F on a candy thermometer, but in the recipe you say until it reaches 240F. Which is correct? I always get hyper when recipes start talking about soft ball and hard ball stages.
Thanks.
Thank you for catching that! I corrected the post. It should get up to 240F.
