Method
Prepare the dish and soften the dates
Heat the oven to 180°C (350°F). Use a 20 x 20 cm (8 x 8 in) baking dish (for 8 servings); for a scaled batch, choose a dish that keeps the batter at a similar depth. Grease the dish with 10 g of unsalted butter for greasing and line the base with baking paper. Cut 225 g of pitted dried dates into small pieces and place them in a heatproof bowl. Pour 240 ml of boiling water over them, stir in 5 g of bicarbonate of soda, and leave for 10 minutes, until the dates are very soft and the liquid looks slightly thickened.
10:00Mix the date sponge

Beat 85 g of unsalted butter for sponge with 150 g of dark brown sugar for sponge for 2 to 3 minutes, until creamy and slightly lighter. Beat in 2 large eggs one at a time, scraping the bowl after each addition, then mix in 5 ml of vanilla extract. In a second bowl, whisk 180 g of all-purpose flour, 4 g of baking powder, and 1.5 g of fine salt for sponge together. Fold half of this dry mixture into the butter mixture, add 60 ml of whole milk, then fold in the remaining dry mixture just until no floury streaks remain. Mash the softened date mixture with a fork, leaving a few small pieces, and fold it through the batter without overmixing.
Bake until risen and fully cooked

Spread the batter evenly in the prepared dish and smooth the top. Bake for 30 to 35 minutes, rotating the dish once if the oven browns unevenly. Start checking at 30 minutes: the centre should spring back lightly, a skewer should show moist crumbs rather than wet batter, and a food thermometer inserted into the centre should register at least 71°C/160°F. Leave the pudding in the dish while you finish the sauce.
30:00Cook the treacle-toffee sauce

Combine 70 g of unsalted butter for sauce, 150 g of dark brown sugar for sauce, 180 ml of double cream, 20 g of black treacle, and 0.75 g of fine salt for sauce in a medium saucepan. Set over medium-low heat and stir until the butter melts and the sugar dissolves. Bring to a gentle bubble, then cook for 5 to 7 minutes, stirring often and lowering the heat if the sauce spits, until it is smooth, glossy, and thick enough to coat a spoon. Start checking the consistency at 5 minutes and handle the hot sugar sauce carefully.
05:00Soak the pudding and serve

Poke the hot pudding all over with a skewer. Pour about one-third of the warm sauce across the surface and spread it to the edges. Leave for 10 minutes so the sauce can sink into the crumb. Cut into portions, spoon over the remaining sauce, and serve with vanilla ice cream (optional).

Smart Substitutions
- No black treacle? Use unsulphured dark molasses for a similarly bittersweet finish.
- No double cream? Use heavy whipping cream with at least 36 percent fat so the sauce thickens smoothly.
- Only light brown sugar? Use it in both the sponge and sauce, then add a little more black treacle to deepen the flavour.
- No dried dates? Use soft pitted prunes for a darker, slightly tangier variation.
Tips and Variations
- Cut the dates into small, even pieces so they soften at the same rate and disappear into the crumb without becoming a smooth puree.
- Fold the flour in only until combined; prolonged mixing makes the sponge tight instead of tender.
- Keep the sauce at a gentle bubble. Fierce boiling can split the butter from the cream or scorch the sugar at the base of the pan.
What Went Wrong?
- Centre is wet after 30 minutes Bake for another 3 to 5 minutes, then check again for moist crumbs and an internal temperature of at least 71°C/160°F.
- Sponge turned dense The batter was probably overmixed or the raising agents were old. Fold gently and use fresh bicarbonate of soda and baking powder.
- Sauce looks greasy Take the pan off the heat and whisk steadily until it comes back together; avoid boiling it hard.
- Sauce became too thick Whisk in a small splash of hot water over low heat until it flows in a thick ribbon again.
