Step 1

Start by pre-heating your oven to 180c. Also grease and line two 8 inch cake tins.

Step 2

In a large bowl, add the cocoa powder, instant coffee and hot water. Whisk these together.

Step 3

Add the oil, buttermilk and eggs into this, whisk until combined.

Step 4

Now add the flour and both sugars, whisk just until you get a smooth batter.

Step 5

In a small separate bowl, add the baking soda and pour the vinegar over it. This will start bubbling, just give it a quick mix and then whisk this into your batter.

Step 6

Pour the batter into your prepared cake tins, then bake in your pre-heated oven for around 30-35 minutes, or until a toothpick inserted into the centre comes out clean.

Step 7

Once baked, leave to cool completely.

Step 8

In a large bowl, break up your cakes until you get fine crumbs. You can either do this in a stand mixer using a paddle attachment, or you can just break the cake up with your hands.

Step 9

Add a large dollop of fudge icing to this and mix this into the cake crumbs. You should be able to get a piece of this mixture and easily roll it into a ball, if it's too dry and crumbly, mix in some more fudge icing.

Step 10

Get about 1-2 tablespoons of this mixture and roll it into a ball. It's up to you how much of the mixture you want to use for 1 truffle, you can make your truffles as big or as small as you want.

Step 11

Place this onto a baking paper lined tray.

Step 12

Keep repeating this until you've used all of the mixture, then leave these in your fridge for about 30 minutes.

Step 13

Add your oil and chocolate into a bowl and melt this. You can either do this in your microwave, or in a double boiler.

Step 14

Using a fork, get one of your truffles and dunk it into the melted chocolate, then place this onto a baking paper lined tray.

Step 15

Keep repeating until you have coated all of your truffles. At this point, I sprinkled some flaky salt over the truffles, but this is optional.

Step 16

Leave these in the fridge so the chocolate can set up, then you can enjoy!
