A simple, moist & flavourful marble cake with the aromas of coffee & orange are sure to delight anyone!
If you don't have soft brown sugar you may use caster sugar and 1 teaspoon of cocoa powder to achieve the dark brown colour that gives this cake a marble effect. However, the cocoa flavour may stand out (I haven't tried it, just a suggestion)
Please check the recipe for the mixed spice from my website. Mixed spice is generally used in Christmas cakes and is a blend of many warm spices. If you don't have mixed spice handy, you can use a mix of coriander, dry ginger powder, cloves, mace, cinnamon, all spice, cardamom & nutmeg. For this recipe I used whatever was handy and just added 1/8th teaspoon each of coriander powder, dry ginger powder, all spice, cardamom, cinnamon & nutmeg powders and about 5 whole cloves & a blade of mace directly to the coffee & walnuts and pulsed them together.
Instead of all purpose flour you may also use readymade self raising flour in which case you can use only 1 teaspoon of baking powder instead of 2 as the self raising flour will already have baking powder in it.
