The flavour we decided to add to our fudge slow cooker recipes is Rum & Raisin Fudge. It’s such a classic flavour combination and one I know so many people love. I’ve tried to make the recipe as simple as possible and it turned out pretty great.

Do you need to use real rum in this recipe?

We wanted to create a family friendly fudge recipe so used rum flavouring which has an incredibly low alcohol content. Alternatively you could use real rum. Also, I didn’t want an overpowering rum flavour and so used just one tablespoon of rum flavouring in the recipe.

However, you could add more rum to the mix if you want a stronger flavour. For each extra tablespoon of rum add an extra 100g of chocolate to make sure it still sets properly.

Slow Cooker Rum and Raisin Fudge

Rum and Raisin is typically a flavour that you find mostly at Christmas but this chocolate fudge recipe is definitely one that you can enjoy throughout the year. It would be lovely to parcel up into individual gift bags to give as presents or to take to someone’s house as a little token gift.

Two things you really need to make sure of when making perfect slow cooker fudge is that you don’t let the fudge burn. Leave it for longer than 10-15 minutes without stirring and it burns easily. Also, make sure you line your tin well with baking paper or use a decent silicone baking tray – you’d hate for it to stick!

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.

Can you make microwave rum and raisin fudge?

A lot of people make fudge in the microwave but I much prefer the control that the slow cooker gives me. However, if you want to try making this chocolate rum and raisin fudge in the microwave, put the ingredients in a microwavable bowl and heat on short bursts in the microwave, stirring regularly.

If you’re looking for other slow cooker fudge recipes to try at home then I have to recommend our Lotus Biscoff Fudge, Peanut Butter Fudge and Kinder Style Fudge but you can see all our fudge recipes so far here.
