METHOD
- Preheat oven to 180°C. Line a 20cm cake tin with baking paper. Cream the butter and sugar until light. Add the eggs one at a time, beating well after each addition. Stir in the vanilla and sweet potato.
- Sift together the flour, baking powder, bicarb, cinnamon and salt. Stir the flour mixture and milk, alternately, into the egg mixture. Fold in the nuts and spoon into the prepared tin.
- Bake for about 40 minutes until a skewer inserted comes out clean. Cool in the tin for 15 minutes before turning out onto a rack to cool completely.
- Meanwhile, for the icing, beat the butter, cream cheese and icing sugar until light and fluffy. Beat in the syrup until a spreadable icing forms (add more icing sugar if it’s too runny or a splash of milk if it’s too dry). Spoon a layer of icing onto the cooled cake.
