Baked Treacle Sponge Pudding Recipe UK Style

Baked treacle sponge is a classic British dessert: a light, fluffy sponge cake baked over a layer of golden syrup, which turns into a rich, sticky sauce as it cooks. This version uses the traditional method of pouring hot syrup into the dish before adding the batter, so you get that perfect contrast of tender crumb and gooey, caramel-like topping. It is a genuinely easy pudding to pull together with store-cupboard ingredients, and it delivers real comfort-food satisfaction every time.

Ingredients

6 tbsp (120 g) golden syrup, plus extra for serving
1 cup (115 g) self-raising flour
1 tsp baking powder
1/2 cup (115 g) unsalted butter, softened, plus extra for greasing
1/2 cup (100 g) caster sugar
2 large eggs, at room temperature
1 tsp vanilla extract
2 tbsp (30 ml) whole milk
Finely grated zest of 1 lemon (optional)

Instructions

Preheat your oven to 350°F (180°C). Generously butter a 2-pint (about 1.2 litre) ovenproof pudding basin or a deep 8-inch (20 cm) round cake dish.
Warm the golden syrup in a small saucepan over low heat for 1-2 minutes until it is runny. Pour it into the bottom of the prepared basin, tilting to coat the base evenly. Set aside.
In a medium bowl, sift together the self-raising flour and baking powder.
In a separate large bowl, beat the softened butter and caster sugar together with an electric mixer until pale and fluffy, about 3 minutes.
Beat in the eggs one at a time, adding a spoonful of the flour mixture with each egg to prevent curdling. Stir in the vanilla extract and lemon zest, if using.
Gently fold in the remaining flour mixture with a metal spoon, then stir in the milk to loosen the batter to a soft dropping consistency.
Spoon the batter carefully over the syrup in the basin, smoothing the top with a spatula. Do not stir the syrup into the batter.
Place the basin on a baking tray to catch any overflow. Bake for 40-45 minutes, until the sponge is golden brown, risen, and springs back when lightly pressed in the centre. A skewer inserted into the sponge (not the syrup layer) should come out clean.
Remove from the oven and let it rest for 5 minutes. Run a knife around the edge, then invert the pudding onto a deep serving plate with a rim, so the syrup runs over the top. Serve hot with extra golden syrup and custard.

Tips

Syrup temperature: Warm the syrup before pouring it into the basin; cold syrup is too thick to spread evenly and can make the sponge base soggy.
No self-raising flour? Use 1 cup (115 g) plain flour plus 2 tsp baking powder and a pinch of salt. The texture will be slightly less tender but still good.
Prevent curdling: If the batter curdles when adding eggs, don’t panic—it will often come back together once the flour is folded in. Make sure the eggs are at room temperature.
Don’t overmix: Fold the flour in gently; overmixing develops gluten and makes the sponge tough instead of light.

Serving Suggestions

Serve this pudding steaming hot with a generous pour of hot custard, which is the classic British pairing. It also works beautifully with thick double cream, vanilla ice cream, or a spoonful of crème fraîche to cut through the sweetness. A pot of strong tea on the side completes the experience.

Variations

Syrup swap: Replace the golden syrup with black treacle (molasses) for a deeper, slightly bitter flavour, or use a mix of half golden syrup and half black treacle.
Citrus twist: Add the zest of an orange instead of lemon, or stir 1 tbsp of orange juice into the syrup before pouring it into the basin.
Spiced version: Add 1/2 tsp ground ginger or mixed spice to the flour for a warming, aromatic note.
Individual puddings: Divide the syrup and batter among 6 buttered ramekins (about 1/2 cup / 120 ml each) and bake for 20-25 minutes.

Storage and Reheating

Leftover pudding can be kept in the refrigerator for up to 3 days, covered tightly with plastic wrap or in an airtight container. To reheat, spoon individual portions into a microwave-safe bowl and heat on medium power in 30-second bursts until piping hot, about 1-2 minutes total. Alternatively, reheat the whole pudding in a 350°F (180°C) oven for 10-15 minutes, covered with foil to prevent drying out. The syrup will thicken as it cools, so add a splash of milk or water when reheating if you want a saucier consistency. Do not freeze this pudding, as the texture of the sponge becomes rubbery when thawed.

Frequently Asked Questions

Can I make this pudding ahead of time? Yes, you can assemble the pudding (syrup and batter) up to a day in advance and keep it covered in the refrigerator. Bake it straight from the fridge, adding 5-10 minutes to the cooking time. Do not bake it ahead and reheat the whole thing, as the sponge will dry out.

Why did my sponge sink in the middle? This usually happens if the oven door is opened too early during baking, or if the batter was overmixed. Keep the oven closed for at least the first 30 minutes, and fold the flour only until just combined.

Can I use a different syrup? Absolutely. Maple syrup, honey, or a thick fruit jam (like raspberry) can replace the golden syrup, though the flavour will change. If using honey, reduce the sugar in the sponge slightly, as honey is sweeter.

Do I need a pudding basin? No, a deep ovenproof dish or even a 9-inch (23 cm) round cake tin will work. Just make sure it is deep enough to hold the batter as it rises without spilling over.

Is this the same as a steamed treacle sponge? Not quite. Steamed versions are cooked in a covered basin over simmering water for about 1.5 hours, giving a denser, moister texture. This baked version is quicker and lighter, with a slightly firmer crumb.

Can I reduce the sugar? You can cut the caster sugar down to 1/3 cup (65 g) without ruining the pudding, but the syrup layer is essential for the sauce—don’t reduce that. The pudding will be less sweet overall, so adjust your serving accompaniments accordingly.
