Preheat your oven to 180ºc/160ºc fan, and line a 2lb loaf tin!
In a microwave proof bowl, add the chocolate and butter and heat and mix until melted
Add the coffee granules to a mug, and pour over the boiling water and mix until smooth
Add the coffee mix into the chocolate/butter and mix until smooth. Leave to cool for five minutes.
In a separate bowl, add the flour, sugar, cocoa powder, baking powder, bicarbonate of soda and spices to a large bowl and whisk until distributed.
Add the cooled chocolate mix to the dry mix and combine
Add the treacle, buttermilk and eggs and mix again as little as possible until combined
Pour the mixture into the lined 2lb loaf tin - only fill your tin 2/3 full. Tins can vary in size, so make cupcakes with spare mix if your tin is too small
bake in the oven for 55-60 minutes, or until baked through. Leave to cool fully
Frosting
Beat the butter on it's own for a few minutes to soften
Add in the icing sugar, and beat until combined.
Add the ginger and treacle and mix through.
Add the cream cheese and mix again until thick and delicious
Decoration
Slather the frosting onto the top of the loaf cake, and then decorate how you want - I used gingerbread biscuits
