Cream butter and sugar.

Add eggs, one at a time.

Add treacle and mix well.

Sift flour, baking powder and spices into mixture and stir to combine.

Add fruit and mix well.

Put mixture into a small, deep cake tin which has been lined well with baking paper. (A 6 inch round tin works nicely with 3 layers of greased baking paper).

Cover cake tin with a piece of baking paper and tie to secure.

Steam for 2 to 2 ½ hours.

Remove paper cover and put into a slow oven for 20-30 minutes to crust.

Remove from oven, cover with aluminium foil and wrap in a clean tea towel to cool.
