METHOD

You will need 1 x approx 23cm / 9-inch square baking dish

1. Preheat the oven to 180°C/160°C Fan/350°F and lightly grease your dish. Put the chopped dates, 200ml/¾ cup of boiling water and bicarbonate of soda into a bowl, give a stir and then leave for 10 minutes.
2. Cream the butter and black treacle until well mixed, then add the sugar and mix again, beating out any lumps. Beat in an egg and keep beating until completely incorporated, then do likewise with the other egg. Beating more gently, add the flour and baking powder until you have a smooth, thick batter.
3. Using a fork, stir the soaked dates, then pour the dates and their liquid into the batter and beat gently to mix in.
4. Pour into your prepared dish or cake tin and bake in the oven for 30-35 minutes, or until a cake tester comes out clean.
5. For the sauce. Melt the butter, muscovado sugar and treacle over a very low heat in a saucepan. Once the butter's melted, stir gently until everything else is melted too. Now stir in the cream, then turn up the heat and when it's bubbling and hot, take it off the heat.
6. As soon as it's out of the oven, prick the cooked sponge pudding all over with a cocktail stick and pour about a quarter of the warm sauce over, easing it to the edges so that the sponge is entirely topped with a thick sticky glaze. Put a lid on the remaining sauce in the pan to keep it warm.
7. Leave for 20-30 minutes, or up to an hour is fine, then take to the table, with the rest of the sauce in a jug, and vanilla ice cream to serve.
