Preheat the oven to 170C/340F/Gas 3

Cream the butter and caster sugar until light and fluffy, I use a stand mixer but you can mix by hand

Next add 1 egg at a time, beating well in between

Next add the coffee and water mix, the soured cream and the flour and combined with a spoon until smooth

Pop it in your lined loaf tin and bake in the centre of a preheated oven

Bake for 45 minutes in the centre of the over, check after 40 minutes and see how it's doing

Once baked , leave to cool

In a small mixing bowl or a cup, add your coffee granules

Add the hot water and stir until the coffee is dissolved

Next add the icing sugar and mic until smooth, no lumps

Once the cake is cooled top the icing on top of the cake and it should drip a little down the sides of the cake

Finish with toasted mixed nuts (optional)
