Easy, delicious, and quick gin and tonic fudge with lime.

Gin and tonic fudge!

So recently I posted my gin & tonic cupcakes recipe and it was a much much MUCH bigger hit that I planned and I just knew I needed to do another gin and tonic recipe, so gin and tonic fudge happened. I have several G&T recipes up my sleeve, and I thought I might as well post another one as its such a popular thing at the minute. Honestly, all the deals, all the popular things are all about gin at the moment!

I recently went to an event with Paul A Young and Four Pillars Gin which was DELIGHTFUL, and delicious.. and it made me want more gin treats in my life. However, for this particular recipe, I thought I would make it cheaper than having to buy a new bottle of gin, and some tonic, and tried the Sainsbury’s gin and tonic flavouring. Obviously, its never going to taste as good as an ice cold G&T, but it does the trick damn well. You can’t really smell G&T out of the little bottle as its so concentrated it kinda just burns. The taste however? Yes please!

Gin and tonic

As I do love a good G&T, I am always for trying the flavour in new and different things. You can try gin & tonic in a condensed milk fudge if you like, but you’d have to use so much to get the flavour through, that the fudge doesn’t really set very well due to the tonic. Trust me, I have tried… it doesn’t work too well. I have also tried more classic types of fudge, and the flavour just doesn’t come through. However, using just gin does work to a degree, as long as its a nicely flavoured one that is quite strong! My gin & tonic cupcakes worked wonderfully with the actual gin, as the gin syrup is utterly dreamy, but for the fudge… I love the essence, or gin on its own.

Recipe adaptations

I put some lime into my fudge to give it a little bit of colour, and to give it a bit of a fruity taste. This is completely optional, I just thought it looked nice! You can easily dye the fudge a colour if you wanted, or change it to milk chocolate, or dark chocolate – its so easily adaptable you will adore it. I hope you love this recipe as much as I, and my taste testers did! Enjoy! x

  • 397 g condensed milk (one tin)
  • 600 g white chocolate
  • 2-3 tsps gin & tonic flavouring (or 75ml gin)
  • 100 g icing sugar (sifted)
  • Zest of two limes


  • Line a tin with parchment paper – I use a 7×10″ brownie tin as it makes a nice depth of fudge!
  • Put the chopped chocolate into a heavy based pan, along with all of the condensed milk, and the gin and tonic flavouring – melt on a low heat, stiring often so that the chocolate doesn’t catch on the bottom and burn and so that all the ingredients mix together well.
  • Alternatively, melt the chocolate in the microwave until fully melted, and mix in the condensed milk and flavouring afterwards.
  • If using actual gin, mix in at the end with the icing sugar in the next stage.
  • Once melted, tip in the sifted icing sugar and combine well, it make take a bit of beating. Add in the zest of one of the limes.
  • Stir through and pour into the tin and smooth over the mixture. Sprinkle on some more lime zest and press into the top of the fudge and store in the fridge for at least 3-4 hours to set, or overnight!
  • Once set – remove from the tin and cut into the squares (I cut 1″ squares) , return to the fridge for another couple of hours to finish setting if its still a little soft – ENJOY!


  • I bought my gin and tonic flavouring from Sainsbury’s as it was nice and cheap and worked well! They also do rum flavouring, and prosecco flavouring.
  • As I said above, I didn’t get on with using real gin or tonic as this is a condensed milk type fudge rather than a proper fudge. Just gin on its own works, but tonic causes it to not set. As a warning, even with the gin it can be still a little soft!
  • If your fudge  is still a little soft, try leaving it in the fridge for another night, and it’ll harden. You can also add in another 200g of white chocolate to help, however that will reduce the flavour of the gin.
  • This fudge will last in the fridge for 2-3 weeks, in an airtight container.

    Can you make this with pink gin?

    • Jane's Patisserie on February 15, 2022 at 2:23 pm

      Hiya, yes absolutely! In baking, Gins can be interchangeable! Hope this helps! x

    I posted this above but under someone else’s comment by mistake, sorry. But you mention biscuits in point number 1 in the method when choosing your tin size? Is this just an error? And if so is it still a 7×10 tin you use to get a nice depth?

    • Jane's Patisserie on January 30, 2021 at 7:51 pm

      Oops that was an error! The tin is still a good size though as that is what I used! x

    Can this fudge be frozen if making it in advance?

    • Jane's Patisserie on December 11, 2020 at 3:46 pm

      Yes it can!

    • Lauren Grigg on December 12, 2020 at 8:59 pm

      Thanks. Is that the same with all your fudge recipes? Can they all be frozen? Am working my way through them – love them all so far!

    • Jane's Patisserie on December 13, 2020 at 9:17 am

      Yes you can – the condensed milk types don’t tend to freeze completely solid but that’s fine!

  4. Lauren Grigg on December 11, 2020 at 9:28 am

    Have you tried to freeze this? Am thinking of making for Christmas gifts but need to make in advance.

  5. Melanie Warren on October 12, 2020 at 4:41 pm

    Hi Do you do any fudge recipe that doesn’t involve chocolate please? I can t eat chocolate in any form
    Thanks x

    • Jane's Patisserie on October 12, 2020 at 6:21 pm

      Yes – have a look at my cookies & cream fudge. It’s a completely different base recipe that is classic, and doesn’t use chocolate!

    Could I make this gluten free?

    • Jane's Patisserie on August 10, 2020 at 9:43 am

      As long as the ingredients are gluten free (you need to check yourself as brands vary), yep.

    Delicious fudge as usual Jane!
    With this being the quick fudge how long do you think it would keep out the fridge if I was to gift some to a friend?

    • Jane's Patisserie on June 28, 2020 at 7:33 pm

      It really depends on the weather – for example with the heatwave we’ve had in the UK recently I wouldn’t say long at all, but in winter it could last a lot longer!

  8. April on April 12, 2020 at 10:20 am

    Hi Jane, I really want to try a pina colada fudge. Do you think I could substitute the gin and tonic extract in this for a coconut extract and rum extract, and it will work the same??

  9. Imogen on May 7, 2019 at 9:30 pm

    Love this fudge recipe, its amazing, can you swap the gin & tonic flavour for a whiskey flavouring

    • Jane's Patisserie on May 8, 2019 at 3:13 pm

      Yes – if its a flavouring. Unsure about actual whiskey!

  10. Imogen on May 7, 2019 at 8:20 pm

    Love this fudge, its amazing, just wondering if you could swap the gin and tonic flavour for a whiskey flavour?

  11. Lynsey on April 30, 2019 at 7:15 pm

    Should it pour out the bowl quite easily? Mine was quite tough & hard to spread. Have I done it wrong?

    • Jane's Patisserie on April 30, 2019 at 7:31 pm

      It should be thick, it means it will set well!

  12. veronica bellotti on March 1, 2019 at 10:08 am

    Im not going to, but would you add the lime juice, or will it not set so well, I’m asking noe for the next time, as you do not say to add juice of the limes.

    • Jane's Patisserie on March 1, 2019 at 5:14 pm

      I wouldn’t – as it can affect the set!

    • veronica bellotti on March 2, 2019 at 11:56 am

      Thank you

  13. Angela on December 11, 2017 at 10:05 am

  14. Barbara mcmaster on November 13, 2017 at 6:21 pm
