Delia Smith All-in-One Victoria Sponge Recipe with Raspberry and Mascarpone Cream

Jump to Recipe

There’s a particular kind of confidence that comes from knowing a sponge cake will work every single time, and that’s exactly what Delia Smith’s all-in-one method delivers.

Rather than creaming butter and sugar first, then folding in flour and eggs in stages, every single ingredient goes into one bowl together and gets whisked until smooth. It sounds almost too simple for a cake this good.

This particular version dresses up the classic Victoria sponge with a filling of mascarpone, fromage frais and fresh raspberries, rather than the usual jam and buttercream.

It comes from Delia’s Vegetarian Collection, where it appears as a lighter, fruit-forward take on the traditional teatime sponge. The all-in-one method itself is one Delia has used across many of her sponge recipes, including her all-in-one chocolate fudge cake and fatless sponge , prized for being fast, forgiving and almost impossible to get wrong.

Why You’ll Love This Delia Smith Recipe

This isn’t just a quick cake — it’s a properly balanced one, where the tang of the fromage frais cuts through the richness of the mascarpone and butter.

• Genuinely fast to prepare — everything goes into one bowl, so there’s no separate creaming or folding stage.
• Forgiving for beginners — the all-in-one method is hard to get wrong, provided the butter is properly softened.
• A lighter filling — mascarpone and fromage frais give a softer, tangier result than traditional buttercream.
• Good make-ahead potential — the sponges bake and cool well in advance of assembly.
• A lovely seasonal option — fresh raspberries make this ideal for late summer, though frozen fruit works reasonably well out of season.

Ingredients You’ll Need

This version is scaled to serve nine, a small step up from the traditional eight-slice sponge, so quantities here are adjusted accordingly from the original recipe.

For the sponge:

• 195g self-raising flour (6.9 oz)
• 1 heaped teaspoon baking powder
• 3 large eggs
• 195g golden caster sugar (6.9 oz)
• 195g butter, very soft at room temperature (6.9 oz)
• ½ teaspoon vanilla extract

For the filling:

• 250g raspberries (8.8 oz)
• 4 tablespoons soft-set raspberry jam
• 280g mascarpone (9.9 oz)
• 225ml fromage frais (7.9 fl oz)
• 1 heaped tablespoon golden caster sugar
• 1 teaspoon vanilla extract

To serve:

• A little icing sugar, for dusting

Equipment: Two 20cm (8in) round sandwich tins, greased and with the bases lined with baking parchment.

How to Make the All-in-One Victoria Sponge with Raspberry and Mascarpone Cream

1. Prepare and combine the sponge batter. Preheat your oven and grease and line the base of both sandwich tins. Sift the flour and baking powder into a large mixing bowl, holding the sieve up high so the flour gets some air as it falls. Add the eggs, sugar, soft butter and vanilla extract straight into the same bowl.
2. Whisk until smooth. Using an electric hand whisk, beat everything together for around a minute, until you have a smooth, well-combined batter with no visible lumps of butter. A wooden spoon works too, though it takes more effort and a little longer. The finished mixture should drop easily off a spoon when you tap it against the side of the bowl — if it feels a touch too stiff, loosen it with a tablespoon or two of water.
3. Divide and bake. Split the batter evenly between the two prepared tins, levelling the tops with the back of a spoon. Bake on the centre shelf for 30–35 minutes. Resist opening the oven door for at least the first 30 minutes, as the sudden temperature drop can cause the sponges to sink in the middle.
4. Check for doneness and cool. The sponges are ready when the centre springs back after a light touch and leaves no visible impression. Leave them in the tins for about 30 seconds, then run a palette knife around the edges to loosen them before turning out onto a wire rack. Peel back the lining paper carefully, then flip the sponges the right way up using a second cooling rack, so they don’t stick as they cool completely.
5. Make the filling. Once the sponges are fully cold, whisk the mascarpone and fromage frais together in a bowl — a balloon whisk brings them together quickly and smoothly. Stir in the sugar and vanilla extract until the mixture is even and slightly softened.
6. Assemble the cake. Spread a tablespoon or so of jam over one sponge, top with half the mascarpone mixture, then scatter over the raspberries. Add the remaining mascarpone mixture on top and drizzle with the rest of the jam. Set the second sponge on top, press down lightly to bring the layers together, and finish with a light dusting of icing sugar just before serving.

Tips for Making the Recipe Successfully

Soften the butter properly. This recipe genuinely doesn’t work with cold or fridge-firm butter — plan ahead and leave it out for a few hours if needed.

Don’t open the oven early. A rush of cold air in the first half of baking is the most common reason for sunken sponges.

Cool completely before filling. Adding the mascarpone mixture to a warm sponge will cause it to melt and slide, ruining the layers.

Whisk the filling just enough. Overworking mascarpone can make it split or become grainy — combine it just until smooth.

Pat raspberries dry if they’re particularly juicy, so excess liquid doesn’t seep into the filling and make it runny.

Level your sponges before baking so the layers sit flush once sandwiched together.

Recipe Variations and Substitutions

These are optional adaptations rather than part of the original recipe, so treat the base sponge and filling above as the definitive version.

Different berries: Strawberries, blackberries or a mixture of summer fruits can replace raspberries when they’re more readily available.

Lighter filling: Swapping some or all of the mascarpone for extra fromage frais reduces the richness, though the filling will be looser and less stable.

Citrus twist: A little finely grated lemon or orange zest in the sponge batter adds a subtle background flavour that works well with the raspberries.

Nut-free reassurance: As written, this recipe contains no nuts, making it a straightforward option for gatherings where nut allergies are a concern (always double-check individual ingredient brands).

What to Serve With This Victoria Sponge

This cake is rich enough to stand entirely on its own as an afternoon tea centrepiece, but a few accompaniments suit it well.

• A pot of good breakfast or Earl Grey tea, in proper Victoria sponge tradition.
• A few extra fresh raspberries or a small spoonful of the same jam used in the filling on the side of each slice.
• For a more indulgent dessert-style serving, a light drizzle of pouring cream alongside, rather than more mascarpone.

If you’re planning a wider spread, Delia’s pavlova is another raspberry-friendly dessert that pairs well on the same table, and homemade plum jam is worth having on hand if you enjoy making your own preserves for the filling.

Common Mistakes to Avoid

Using cold butter. The all-in-one method depends on the butter being genuinely soft. Cold butter won’t combine properly, leaving a lumpy batter and an uneven crumb.

Opening the oven door too soon. Checking on the sponges before the 30-minute mark lets cold air in and can cause them to sink in the centre before they’ve set.

Filling the cake while it’s still warm. Even slightly warm sponges will melt the mascarpone filling, causing it to slide out from between the layers.

Overloading the filling. Piling on too much mascarpone mixture or too many raspberries makes the finished cake unstable and difficult to slice neatly.

Skipping the tap test. Relying purely on the timer without touching the centre of the sponge can lead to underbaked or overbaked results, since ovens vary.

Can You Make This Recipe Ahead?

The two sponge layers can be baked a day in advance and kept, once completely cool, wrapped in cling film or stored in an airtight container at room temperature.

The mascarpone filling is best made close to when you plan to assemble the cake, since it can lose some of its texture if left to stand too long.

Assembling the whole cake a few hours ahead of serving is fine, and the flavours settle nicely in that time, but for the best texture, it’s worth adding the final icing sugar dusting just before serving rather than in advance.

How to store leftovers

Once filled, this cake needs to be kept in the refrigerator, ideally in an airtight container, because of the fresh dairy filling.

It’s best eaten within a couple of days for the freshest texture, as the raspberries will start to release moisture into the filling over time.

The unfilled sponge layers freeze well if wrapped tightly in cling film and foil, and can be defrosted at room temperature before filling and assembling.

The finished, filled cake is not a good candidate for freezing, as the mascarpone and fromage frais filling doesn’t defrost cleanly.

Frequently Asked Questions

How do I make my Victoria sponge light and fluffy?

For a light and fluffy Victoria sponge, make sure the butter is properly softened so it combines smoothly with the other ingredients. Mix the batter until it is evenly combined and has a smooth, soft consistency, but avoid excessive mixing.

Use the correct amount of raising agent, divide the batter evenly between the tins and avoid opening the oven too early.

Bake until the sponge is well risen and the centre springs back when lightly touched.

What is the difference between a sponge cake and a Victoria sponge cake?

A sponge cake is a broad term for cakes with a light, airy texture, and there are many different types. A Victoria sponge is a specific style of sponge cake made as two layers and traditionally sandwiched together with jam and cream.

This all-in-one version follows the same basic two-layer concept but uses a raspberry, mascarpone and fromage frais filling, giving it a fruitier and creamier finish.

Can this cake be frozen?

The unfilled sponge layers freeze well. The assembled cake, with its mascarpone and fromage frais filling, doesn’t freeze successfully and is best made and eaten within a few days.

Can I change the serving size?

Yes, all the quantities here scale up or down consistently. Just keep the ratios between flour, sugar, butter and eggs the same as you adjust.

What can I substitute for fromage frais?

Natural yoghurt is the closest substitute, though it will make the filling slightly tangier and a touch looser than fromage frais.

Why did my sponge turn out dense or heavy?

This is almost always down to butter that wasn’t soft enough, or a batter that wasn’t whisked for long enough to fully combine and aerate.

How do I know when the sponge is properly cooked?

Touch the centre lightly with a fingertip. If it springs back with no lasting impression, it’s done. If it leaves a dent, give it another few minutes.

Can I double the recipe?

Yes, though you’ll need four sandwich tins, or you’ll need to bake the sponges in batches, since doubling the batter in one bowl can make it harder to whisk evenly.

Conclusion

Delia Smith Victoria Sponge All In One​ is a cake that proves you don’t need an elaborate method to get an impressive result. The all-in-one sponge does the heavy lifting in minutes, and the raspberry and mascarpone filling turns a familiar teatime bake into something that feels a little more special.

It suits everything from a relaxed weekend bake to a proper celebration centrepiece, and it’s worth having in your regular rotation for exactly that reason.
