  • 400g golden caster sugar
  • 397g can condensed milk
  • 140g salted butter, chopped into pieces
  • 1 tsp vanilla bean paste
  • 2 tbsp coffee liqueur (or another alcohol of your choice - amaretto or brandy works well)



    Brandy is a distilled spirit made from virtually any fermented fruit or starchy vegetable.…


  1. Grease and line a 20cm square baking tin with baking parchment. Put the sugar, condensed milk and butter in a large heatproof bowl (the mixture will bubble up as it cooks to roughly double its size), add a good pinch of salt and stir together.

  2. Heat the mixture in the microwave on High for 10 mins, stirring every 2-3 mins. Keep an eye on the mixture, as it will bubble up and may go over the sides of the bowl.

  3. Add the vanilla and liqueur to the mixture, whisk together and heat on High for another 2 mins. The mixture should be caramel-coloured and thickened. Scrape into the tin and set aside for 45 mins to 1 hr until cool and firm before cutting. Pack into a box and eat within 3 weeks.

I've tried three times.....first one I followed exactly to the recipe, but the result was too gooey. I swirled the resulting goo in with ice cream. Second one I decided to make sure I kept heating it and lost count of how much it was heated - it turned out like toffee, and pulled one of my fillings out. There were some small parts within the toffee which were crumbly and fudge like, but in the minority. I concluded that I'd over heated it. Tried a third time to hit the Goldilocks spot, but even 10 x 2 minutes stirring well in between, and it's far too gooey. I'm giving up now!

This worked out great for me, I put in 4 tbs of Kalua (because, why not?) and it was delicious. I beat it with a fork every two minutes and zapped it a few extra times. It was a bit grainy but I prefer my fudge to be more like tablet than toffee. I also put walnuts in. Gave half as a gift.

This fudge was lovely, no booze but 2tbl spoons of strong coffee, it only took 8 mins in 900w microwave. This was first time doing it in microwave I will do this again its quicker and less mess.

Okay if you have your own teeth and like treacle toffee - I do recommend booking a dental appointment before trying it!

It took me longer to microwave than suggested - probably a total of 16-18 mins. But it produced a decent vanilla fudge (I didn't put the alcohol in) - and is so much quicker and easier than the stovetop method. I'll use the method for every type of fudge from now on.

After reading the comments I was worried that it would be gritty so I beat the mixture after each 2 minutes in the microwave. I added Baileys at the end, then whisked the mixture for about 4-5 minutes. The result is creamy fudge. Perfect.

This is delicious but is more of a Scottish tablet than a fudge. The texture is crumbly as per the picture and not soft and pliable as fudge would be. It is worth making though and will do so again. I haven't used alcohol but added chopped walnuts instead. Very nice and would recommend if you are happy with a crumbly texture ..... a lot less of a faff than normal fudge making!

The fudge turned out perfect and crumbly, just the way I like it. Cutting was difficult given that it was crumbly, but it tasted great. I left the alcohol out btw.

Delicious and super quick and easy. My test batch was sticky and a bit crystalised once fully set, so for the second attempt I beat the mixture by had for several minutes after all the cooking until it was starting the really thicken and om the verge of wanting to set. The result isn't a crumbly fudge, but instead is gorgeously smooth!

I have just put this back in the microwave after 1 hour was too sticky. Have followed recipe exactly. It tastes of condensed milk. I am hoping that the second heating solves the problem. These are for gifts!!!

Could you place all ingredients in slow cooker on low for 2 hours and stir every 15 mins instead? Would this also work by putting juice from an orange in instead of alcohol? Try I g to adapt recipe for children at school to make. Thanks

Can you replace condensed milk for coconut milk and would you need to reduce the sugar?

Thanks for your question. No unfortunately you can't replace coconut milk with condensed milk in this recipe. Making fudge is a fine balance and we would always recommend following the recipe.

Made this as per instructions but apart from the middle square inch it just didn't set! The rest was more like caramel. What went wrong? Thanks

I found it needed longer than the recipe, mine took about 15 mins :)

I have loved in the US for seven years and have never managed to track down golden caster sugar: would regular white sugar produce the same results? I want to try this out for last minute colleague gifts

Really disappointed with this recipe - has this really been tested multiple times?! It's a sticky mess - any suggestions for how to save it before the whole lot goes in the bin?
20th Dec, 2016
It probably needed longer than the recipe. Mine didnt start bubbling until the 10mins and wasnt ready until about 15!

Hi there, sorry to hear you're not having success with this recipe. All our recipes are triple tested however microwaves do differ slightly so if it is still very soft after being left to set for 45mins-1hr transfer the mixture back into the heatproof bowl and return to the microwave for another 2-3 mins. Store in a cool, dry place but not in the fridge as this can make it sticky.
