Si and Dave made the ultimate dessert with their spiced cream and blackberries sponge on The Hairy Bikers Comfort Food show.

The ingredients for the sponge: 225g butter, softened, 225g caster sugar, 4 free-range eggs, 225g self-raising flour, 2 tbsp lemon juice.

For the blackberries: 1 punnet blackberries, 1 tbsp caster sugar and 1 tbsp blackberry liqueur, such as crème de mure (optional).

For the spiced cream: 250ml double or whipping cream, 2 tbsp icing sugar, ½ tsp ground cardamom, ¼ tsp ground allspice, ¼ tsp ground cinnamon and ¼ tsp ground mace.

Si and Dave says: “You could use spelt flour instead of plain flour for a slightly nutty flavour, which works really well with blackberries. If you do, add 2 teaspoons of baking powder.”
