Slow Cooker Milk Chocolate Fudge

Fudge has a reputation for being temperamental but this slow cooker version is not. You don’t need a sugar thermometer, a double boiler or any special equipment. Just a slow cooker, a good block of milk chocolate and a bit of patience while it does its thing.

This milk chocolate fudge is rich, creamy and very hard to stop at one piece! The texture is slightly softer than old-fashioned cooked fudge, which is exactly what makes it so good. It slices cleanly, keeps well in the fridge and makes a lovely gift if you can resist eating it all first.

If you have made my popular Microwave Milk Chocolate Fudge before you will know the texture I am going for here. This slow cooker version gives you the same result but it is more forgiving. The microwave method is fast but it can seize or overcook if you are not watching it closely. The slow cooker takes longer but it is much harder to get wrong.

What you need to know before you start

There is one stage in this recipe that looks wrong before it looks right. In the first hour the chocolate will soften but will not look fully melted. It can appear thick, slightly dull or dry at the edges. This is normal. Do not add liquid, do not turn up the heat.

Around the one hour mark, stir it properly, folding in from the edges and then through the whole mixture. It will come together and go glossy quite quickly once it is ready.

Once it is glossy, stop. If you keep working it past this point the fat will separate from the chocolate and it will turn oily. Stir to combine, stop when it looks glossy.

If you have ever had microwave fudge seize up on you, this method solves that problem. The slow gentle heat means the chocolate melts gradually rather than in short sharp bursts, which gives you much more control.

What chocolate to use

This is the one place in this recipe where it is worth spending a little more. A good quality milk chocolate block makes a real difference to the final flavour and texture. I use Whittakers or Cadbury milk chocolate, both work well and are easy to find at any supermarket in NZ and Australia.

Do not use cooking chocolate or chocolate melts. They are formulated differently and the texture of the finished fudge will not be the same. Use a block you would happily eat on its own.

What the butter and golden syrup do

Both are optional but both are worth including. The butter smooths the texture and gives the fudge a slightly more melt-in-the-mouth quality when it sets. The golden syrup adds a gentle caramel note that lifts the chocolate without you being able to identify it as a separate flavour.

If you do not have golden syrup, leave it out and the fudge will still be excellent.

How to press and set the fudge

Once the mixture is glossy and ready, move quickly. It thickens as it cools so you want to get it into the tin while it is still pourable.

Use a spatula to press and spread it level. This mixture is thick so you need to press rather than smooth. If you are struggling, press gently with the palm of your hand first to get the level right, then neaten with the spatula. A gentle jiggle of the tin also helps it settle into the corners.

How to cut clean slices

Run a sharp knife under hot water and wipe it dry before each cut. The warmth of the blade helps it slice cleanly through the set fudge without dragging or crumbling.

Slow cooker milk chocolate fudge variations

This base recipe is so easy to adapt. Here are a few that work well.

Rocky Road Fudge Once you have stirred through the vanilla and salt, fold through 60 grams of mini marshmallows, 60 grams of roughly chopped roasted peanuts or almonds, and 50 grams of jelly lollies cut into small pieces. Press into the tin and set as directed.

Caramel Swirl Fudge Pour the fudge into the tin then drop spoonfuls of tinned caramel, Highlander works well here, or dulce de leche, over the surface. Use a skewer to swirl through gently before setting. Do not over-swirl or the two layers will combine rather than staying distinct.

Peppermint Chocolate Fudge Replace the vanilla extract with half a teaspoon of peppermint extract and fold through 60 grams of roughly crushed candy canes or Peppermint Crisp before setting. A good one to make coming up to Christmas.

Cherry Ripe Fudge After stirring in the vanilla and salt, fold through four roughly chopped Cherry Ripe bars. The coconut and cherry pieces distribute through the fudge as it sets. Very good.

Turkish Delight Fudge Same method as the Cherry Ripe version but with four roughly chopped Turkish Delight bars instead. The rose flavour comes through gently against the chocolate and it looks beautiful when sliced.

Gifting this fudge

This fudge makes a lovely gift, especially around Christmas. The one thing to keep in mind is that it needs to stay chilled. It softens at room temperature and does not hold up well sitting out for long periods.

If you are giving it as a gift, package it in a box or jar with a little note to keep it refrigerated and it will keep well for up to two weeks.

How to store slow cooker milk chocolate fudge

Keep it in an airtight container in the fridge with baking paper between the layers so the pieces do not stick together. It keeps well for up to two weeks.

To freeze, place in an airtight container with baking paper between layers and freeze for up to three months. Thaw overnight in the fridge.

Questions about this recipe

Why does my fudge look oily or separated? It has been stirred past the point of being glossy. Once the mixture comes together and looks smooth and shiny, stop. Continuing to work it causes the fat to separate from the chocolate. Stop as soon as it looks glossy and you will be fine.

Can I use dark chocolate instead of milk? Yes. Dark chocolate will give a less sweet, more intense result. Use the same quantity and the same method. The texture may be slightly firmer when set.

Can I double the recipe? Yes. Use a larger slow cooker and a 20 by 30 centimetre tin. The cook time will be similar but check it from the one hour mark as usual.

My fudge is too soft even after chilling overnight. What happened? Usually the mixture was not fully glossy before it went into the tin and needs a little longer in the slow cooker next time. If it is very soft after overnight chilling, pop it in the freezer for 30 minutes before slicing and keep it in the coldest part of the fridge.

Can I add nuts? Yes. Fold through roughly chopped roasted almonds, walnuts or macadamias along with the vanilla and salt. About 80 grams works well.

How is this different from microwave fudge? The ingredients and finished texture are very similar to my Microwave Milk Chocolate Fudge. The difference is the method. The microwave version is faster but needs close attention and can seize if it gets too hot, which can easily happen as all microwaves are so different.

The slow cooker takes longer but the gentle heat makes it much harder to get wrong. If you have had trouble with microwave fudge in the past, this is the one to try.
