I’ve been trying to come up with more fudge flavours that you might enjoy and one classic flavour combination is Coffee and Walnut. I thought this would make a great fudge flavour and as Dave is the coffee drinker in our house I enlisted his help to get the balance right with this recipe.

What coffee should I use for this fudge?

This easy fudge can be made with any liquid brewed coffee. By that I mean don’t just put instant coffee granules into the mix – the results won’t be the same. Dave made an espresso and we used that but instead you could make a cup of instant coffee or your favourite coffee and add two tablespoons to the mix before drinking the rest. If you don’t have or drink coffee you could buy coffee flavouring instead.

We found two tablespoons of coffee was enough in this slow cooker fudge recipe to give a good coffee flavour without being overpowering. If you’d like a more subtle flavour you could use one tablespoon of coffee instead but you would also need to alter the amount of chocolate in the mix – around 500g in total. It would be the same if you add more coffee – add more chocolate to compensate.

Although this is a chocolate fudge the coffee replaces the chocolate flavour to give a really lovely homemade coffee fudge recipe and the chopped walnuts add a nice texture to the coffee walnut fudge too. If you’re allergic to nuts, just don’t like them or would prefer plain chocolate coffee fudge just leave the walnuts out for a nice easy coffee fudge recipe. Likewise, you could add any other dried ingredients you feel like to the mix – dried fruit, other nuts. The choice is yours.

You could also make this into a chocolate walnut fudge by leaving the coffee out and reducing the chocolate to 400g in total. This would be a really easy walnut fudge recipe and one that anyone who isn’t keen on coffee – like me – would enjoy.

Can you make this fudge in the microwave?

You can easily make this into a microwave coffee fudge recipe by putting all the ingredients in a microwave bowl instead of the slow cooker and heating on bursts, stirring in between until the right consistency is achieved. However, I much prefer the control I have when using a slow cooker.

How long does slow cooker fudge keep for?

This slow cooker fudge keeps well in the fridge, in an airtight container for a couple of weeks. The flavour matures over the first couple of days of it being in the fridge so you get the full flavour after it’s been in the fridge for a few days.

Can you make slow cooker fudge with evaporated milk?

Our slow cooker fudge works because condensed milk has a really high sugar content, needed to create that beautifully rich fudge. Evaporated milk isn’t the same, doesn’t have that sugar content and isn’t thick enough to help the fudge thicken and set. You can’t use evaporated milk in these recipes – so get some condensed milk instead.

Do you cook slow cooker fudge high or low temperature?

We always cook fudge on a high slow cooker temperature setting and it takes around 40 minutes in total. You could make it on the low setting but it would take longer and would still need to be stirred regularly. You may as well keep the slow cooker on high and be done in under an hour!

When cooking, is the slow cooker fudge lid on or off?

When making slow cooker fudge, you need to remove the slow cooker lid otherwise excess moisture would be retained in the slow cooker pot and the fudge wouldn’t thicken as it needs to.

Fudge is fantastic to give as a gift at Christmas or at any other time throughout the year. We put fudge pieces in individual cellophane gift bags and tie them with a ribbon – it’s always such a thoughtful but simple gift and this flavour especially is wonderful if you love coffee.
