Mars Bar Fudge | 3 Ingredient Fudge Recipe (1)

The problem with not being able to resist a bargain when you see it, is that you inevitably end up with things you a. forget about b. you don’t need or c. you end up withwaaay too many. When I did a recent stocktake of the pantry I was a little shocked to discover a total of 14 Mars Bars hidden in various places so I knew I needed to turn them into something before the urge to start eating them began. I decided to adapt my easy ChocolateMalteser Fudge recipe and turn it into three ingredient Mars Bar Fudge.

Why you will love this recipe:

  • It’s no bake!
  • You don’t need a sugar thermometer
  • You can make this fudge up to one week in advance
  • It’s an easy dessert

    Can I do this in my slow cooker as this is how I make my fudge all the time. it look’s so delicious & yummy off to my local IGA for some mars bars I do have heaps of different chocolate in my freezer but no mars bars unfortunately do U need to let it cool a bit be4 adding the mars bars?

      Hi Judith, I’ve never tried making this fudge in a slow cooker before so I’m not sure how it would go. It only needs to cook for around 8 – 10 minutes and it’s a good idea to add the mars bars straight away as the fudge does start to set quite quickly. I hope that helps xx

    Just made these and the texture was perfect! The sweetened condensed milk came in a 300ml can, and, not wanting to open another can for the extra 95ml, thought I would risk just adding the 300ml. It turned out nice and firm and was still easy to cut. Also, as I had a lot of unsweetened squares of cholocate on hand, and the mars bars and milk are already very sweet, the flavor was perfect too. Thanks for sharing such an easy recipe!

    Tried this one out, but even after leaving in the fridge overnight, it still hadn’t hardened 🙁

    I suspect that this might be because the Cadbury Milk Chocolate here in Australia has different ingredients so that it doesn’t melt in our hot climate during transport.

    It has ended up more like a chunky mousse – the flavour is delicious though!

      Hi Danni,
      I’m glad you can still enjoy the fudge even though it hasn’t set properly for you. I’m also from Australia too (Brissy girl!) and find that the fudge doesn’t set rock hard overnight, it still has a little give to it and is more like a soft fudge.

What makes fudge fudge? ›

Fudge is a dense, rich confection typically made with sugar, milk or cream, butter and chocolate or other flavorings. The base for fudge is boiled until it reaches the soft-ball stage (135 to 140 degrees F), then stirred or beaten as it cools to minimize the formation of sugar crystals.

How do you make your fudge thicker? ›

If your fudge is soft or runny, it probably didn't come up to a high enough temperature while it was cooking. Put it back into the saucepan and add 1–2 US tbsp (15–30 ml) of 35% fat whipping cream. Stir the fudge as it heats, but only until the sugar in the chocolate is completely melted again.

What is the secret to smooth fudge that is not gritty? ›

Once a seed crystal forms, it grows bigger and bigger as the fudge cools. A lot of big crystals in fudge makes it grainy. By letting the fudge cool without stirring, you avoid creating seed crystals.

Can you fix fudge that didn't set? ›

It sounds like your fudge simply wasn't heated enough. ... If it's overcooked (resulting in grainy fudge) or undercooked (resulting in poor setting) all you really need to do is add a bit of cream, reheat the fudge to the target temperature, and let it set again.

What gives fudge its firm texture? ›

The key to creamy, luscious fudge is controlling crystal formation. If the sucrose (table sugar) crystals are small, the fudge will feel creamy and smooth on your tongue. But if the crystals are large, the fudge develops a crumbly, dry, or even coarse texture.

Why did my fudge turn out grainy? ›

If your fudge is tough, hard, or grainy, then you may have made one of several mistakes: You may have overcooked it, beaten it too long, or neglected to cool it to the proper temperature.

Why is fudge unhealthy? ›

Fudge almost always has a pretty high sugar content as well as having some cream in it—both fattening. If you compare that to eating pure dark artisanal chocolate, it is a no-brainer. Dark chocolate of 70% cocoa or higher is considered a health food and often contains only two ingredients: cocoa and organic cane sugar.

What is traditional fudge made of? ›

At its simplest, fudge is a dense, soft candy, often made with sugar and dairy products like butter and milk. Nowadays, fudge is usually flavored with chocolate, but you can utilize pretty much any flavor, such as peanut butter, pumpkin, even birthday cake.

Should I stir fudge while boiling? ›

Stir the ingredients to dissolve the sugar until the mixture comes to a boil. If your recipe uses milk, stirring will keep the mixture from curdling. But once it reaches about 236–238 degrees F/113–114 degrees C (the "soft-ball" stage), do not stir it or even shake the pan.

Can you stir fudge too much? ›

Never stir the mixture during cooking or sugar could crystallize again. The mixture may seize and become grainy. Use a candy thermometer or conduct a cold water test to check if the fudge is done.

What happens if you boil fudge too long? ›

Too cooked

The result is hard and brittle fudge. To save the fudge, put it in a saucepan with 45 to 60 ml (3 or 4 tbsp.) of 35% cream and bring to a boil, stirring until the sugar is completely melted. Then let it boil without stirring until the thermometer reaches 114 to 115 °C (237 to 239 °F).

When should I stop beating fudge? ›

One of the most difficult steps in making fudge is knowing when to stop beating. Once the candy becomes thick and almost holds its shape when dropped from the spoon, it's time to quickly stir in the nuts and push the mixture into the prepared pan (Step 8).

What makes high quality fudge? ›

You have to control two temperatures to make successful fudge: the cooking temperature AND the temperature at which the mixture cools before stirring to make it crystallize. Confectionery experiments have shown that the ideal cooking temperature for fudge is around 114 to 115 °C (237 to 239 °F).

Should you stir fudge constantly? ›

Stir Constantly: Stir the fudge mixture continuously, especially during the melting process, to prevent burning and ensure even cooking. Use Sweetened Condensed Milk: Sweetened condensed milk adds sweetness and creaminess to fudge, creating a smooth texture.

Do you stir fudge while it is boiling? ›

Brush the sides of the pan with a wet brush at the beginning of cooking to dissolve sugar crystals stuck to the sides. Never stir the mixture during cooking or sugar could crystallize again.
