In a large pan or pot, add all the ingredients for the brigadeiro.

Place this onto medium heat and heat, whiles constantly stirring, until the mixture thickens. It should be a thick custard like texture.

Pour this into a bowl and cover with cling film, making sure the surface of the cling film is touching the surface of the brigadeiro.

Leave this in your fridge to cool down and thicken up.

Start by pre-heating your oven to 180c. Also grease and line a 9 inch square cake tin, leave this aside.

In a large bowl, add the cocoa powder, coffee and hot water. Whisk these together, then leave this aside to cool down for 5-10 minutes.

After it has cooled down, add the softened butter, oil and both sugars. Beat these together for 5 minutes.

Add 3 of the eggs into this and mix. Then add the remaining eggs and also the buttermilk, mix these in too.

Now add the flour and mix just until you get a smooth batter.

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

Pour this batter into your prepared cake tin and bake for around 50 minutes - 1 hour. Or until a toothpick inserted into the centre of the cake comes out clean.

Once baked, leave aside to cool down completely.

In a pot, add the ingredients for the milk soak.

Heat this on medium heat until the cocoa powder has dissolved. You could also do this in your microwave.

Leave this aside to cool down too.

Once the cake has cooled down completely, and the milk soak has cooled down too, we can put the cake together.

Start by cutting the cake in half, horizontally, so you have 2 cake layers.

Get a 9 inch square cake tin, this can be the same one you baked the cake in. But clean it first.

Add one of the cake layers into the tin.

Pour half of the milk soak over this. Then add ⅔ of the brigadeiro into the tin. Spread this out.

Add the second layer of cake on top, then pour the rest of the milk over it.

Add the rest of the brigadeiro and spread this out.

Now add some chocolate sprinkles on top.

Leave this to chill and set up in your fridge overnight.

The next day, cut it into pieces and enjoy!
