What You’ll Need
For the Sponge Cake:
- 100g self-raising flour – sifted (¾ cup + 1 tablespoon)
- 100g caster sugar – superfine sugar works best (½ cup)
- 100g unsalted butter – softened to room temperature (7 tablespoons)
- 2 large eggs – room temperature for best mixing
- 1 teaspoon vanilla extract – optional but recommended
- 1-2 tablespoons milk – if needed for consistency
For the Classic Filling:
- 3 tablespoons strawberry jam – good quality for best flavor
- 150ml double cream – whipped to soft peaks (⅔ cup heavy cream)
- 1 tablespoon icing sugar – for dusting (powdered sugar)
For the Equipment:
- Two 6-inch round cake tins – shallow sandwich tins preferred
- Electric mixer – hand mixer or stand mixer
Substitutions:
- No self-raising flour: Use plain flour + 1½ teaspoons baking powder
- No caster sugar: Blend granulated sugar in a food processor until fine
- Dairy-free: Use vegan butter and plant-based cream alternative
- Different jam flavors: Raspberry, blackcurrant, or apricot work beautifully
Step-by-Step Directions
- Preheat oven to 180°C (160°C fan/Gas Mark 4/350°F). Grease two 6-inch cake tins thoroughly with butter and line the bases with baking parchment. This ensures easy release and prevents sticking.
- Prepare your ingredients. Ensure butter and eggs are at room temperature—this is crucial for the all-in-one method to work properly. Cold ingredients won’t cream together effectively.
BBC baker’s tip: Leave eggs in warm water for 5 minutes to quickly bring them to room temperature if you’ve forgotten to take them out early!
- Use the all-in-one method. Place the butter, sugar, eggs, flour, and vanilla extract all into a large mixing bowl. Beat with an electric mixer for 2-3 minutes until the mixture is pale, smooth, and well combined.
- Check the consistency. The mixture should drop easily from a spoon. If it’s too stiff, add 1-2 tablespoons of milk and beat for another 30 seconds.
- Divide the mixture evenly. Spoon the batter into your prepared tins and level the tops gently with the back of a spoon. Try to get them as even as possible for uniform layers.
Professional tip: Weigh your filled tins to ensure even layers—they should be within 10g of each other for perfectly matched sponges!
- Bake for 18-20 minutes until the cakes are golden brown, spring back when lightly touched, and have started to pull away from the sides of the tins.
- Cool properly. Leave in tins for 2-3 minutes, then turn out onto a wire rack to cool completely. Don’t attempt to fill warm cakes—they’ll collapse!
- Prepare the filling. Whip the cream to soft peaks—be careful not to over-whip or it will become grainy and difficult to spread.
- Assemble your sponge. Place one cake layer on your serving plate. Spread the jam evenly to within 1cm of the edge, then add the whipped cream on top. Gently place the second layer on top.
- Finish with style. Dust the top with icing sugar using a fine sieve for that classic British bakery appearance.
Assembly secret: Spread jam first, then cream—this prevents the jam from making the cream runny and helps everything stay in place when you cut!
How to Serve
This 6 inch sponge cake is perfect for a proper British afternoon tea! Serve with a pot of Earl Grey or English Breakfast tea for the full experience. Cut into 8 neat wedges using a sharp knife, cleaning the blade between cuts for professional-looking slices.
For special occasions, garnish with fresh strawberries arranged around the top, or add a few mint leaves for color. The cake also pairs wonderfully with fresh berries on the side.
Timing tip: This sponge is best eaten within 4-6 hours of assembly when the layers are still distinct and the cream hasn’t softened the cake too much.
Expert Tips for Success
The golden ratios: Traditional British sponge uses equal weights of butter, sugar, flour, and eggs. This 100g base recipe follows that classic formula perfectly.
Temperature matters: Room temperature ingredients are non-negotiable for this method. Cold butter won’t cream properly, and cold eggs can cause the mixture to curdle.
Don’t over-mix: Once you add the flour, mix just until combined. Over-mixing develops the gluten and creates a tough, dense cake instead of a light sponge.
Storage wisdom: Unfilled sponges keep for 2 days in an airtight container or freeze for up to 3 months. Once filled, eat the same day for best results.
Jam selection: Choose a jam with good fruit content and not too much pectin—it should spread easily without tearing the delicate sponge.
BBC baker’s secret: Warm your jam slightly in the microwave (10-15 seconds) to make it easier to spread without damaging the sponge surface!
Common Questions
Why did my sponge turn out dense and heavy?
This usually happens when ingredients are too cold, the mixture is over-mixed, or the oven temperature is too low. Make sure everything is at room temperature and mix just until smooth.
Can I make this without an electric mixer?
While possible, it’s much harder work! Cream the butter and sugar by hand for at least 5 minutes until very pale, then beat in eggs one at a time. The all-in-one method really needs electric mixing power.
How do I know when the sponge is perfectly baked?
Look for golden-brown color, cakes that spring back when lightly touched, and slight shrinkage from the tin sides. A skewer inserted in the center should come out clean.
Can I use different size tins?
Yes! For one 6-inch deep tin, bake for 25-30 minutes. For 12 cupcakes, bake for 15-18 minutes. The mixture also works in a 7-inch tin with slightly reduced baking time.
What if I don’t have self-raising flour?
No problem! Use 100g plain flour mixed with 1½ teaspoons baking powder. Sift them together twice to ensure even distribution.
How can I make my sponge extra light?
Some bakers swear by separating the eggs, beating the whites to soft peaks, and folding them in last. This creates an even more delicate texture, though it’s not the traditional BBC method.
