Steamed sponge puddings are the backbone of the English hot dessert tradition, and the golden-syrup or treacle sponge is the most-loved variant. They became universal in Victorian and Edwardian kitchens once cheap refined sugar and raising agents were available, and the steaming method suited the working kitchen that had a pot on the boil for the family's main course anyway. Golden syrup itself is a British creation of the 1880s: Abram Lyle opened his sugar refinery on the Thames at Plaistow in 1881, and the syrup was formulated there by the refinery's chemist Charles Eastick and first sold in its green-and-gold tins in 1885, the tins bearing the lion and bees from Samson's riddle on the label; the firm later merged into Tate and Lyle. The steamed sponge is built on eggs, flour, butter and sugar beaten to a light foam, the syrup swirled or layered in, then steamed in a covered basin for about 90 minutes. It is unrelated to the baked treacle tart, which is a shortcrust case filled with syrup-and-breadcrumb.
A hot, light, yellow sponge, sticky with syrup through its crumb, with a pooling of golden syrup at the bottom of the basin and more poured on top. Intensely sweet, buttery, soft; the custard loosens and warms it further.
The sponge relies on trapped air beaten into eggs and butter for its rise, with a little baking powder as insurance, and it must be light enough to steam without collapsing. The basin is first coated in a layer of golden syrup, the sponge batter spooned over, then the basin covered with a pleated lid of buttered foil that lets steam in while keeping water out. Steaming for 90 minutes sets the sponge gently and evenly, no crust forms as in baking, and the bottom syrup soaks upward into the crumb. The finished pudding is inverted so the syrup pool now crowns the sponge. The key is the foil pleat: a flat cover pools condensation on the sponge and makes it heavy; the pleat directs drips to the side. More syrup is always poured at the table.
Variations
Black treacle replaces golden syrup for a darker, more bitter pudding. Some fold chopped dates into the batter for a sticky-toffee note. A modern oven-baked version in a loaf tin is quicker but lacks the soft steamed texture.

How it's made
7 steps · 20 min
- 14 min
Butter a 1-litre pudding basin generously and pour 3 tbsp golden syrup over the base and sides.
- 26 min
Beat 100g softened butter with 100g caster sugar until pale and fluffy, then beat in 2 large eggs one at a time with a tablespoon of the flour to prevent curdling.
Watch outBeat the butter and sugar until pale and fluffy — that trapped air is the sponge's whole rise, since steaming won't add lift.
- 35 min
Fold in 100g self-raising flour and 1 tsp baking powder with a splash of milk to a dropping consistency.
- 44 min
Spoon the batter into the syrup-lined basin and level the top.
- 54 min
Cover with a pleated sheet of buttered foil, pleat uppermost, tied tightly under the rim with string; make a string handle.
Watch outPleat the foil and tie it tight — the pleat lets the sponge expand and the seal keeps steam-water out of the pudding.
- 68 min
Steam in a covered pan of simmering water for 90 minutes, topping up with boiling water, until a skewer comes out clean.
Watch outKeep the water at a steady simmer and top up with boiling water — let it boil dry and the pudding scorches and stops rising.
- 75 min
Loosen, invert onto a plate; pierce the top and pour over 2-3 more tbsp warmed golden syrup; serve with custard.
