Baking a classic Victoria sandwich with equal weights

Why equal weights make the difference

The Victoria sandwich is the most forgiving cake in the British repertoire, and it is also the one most often ruined by a careless hand with the flour. The traditional method — weigh your eggs first, then match butter, sugar and flour to their weight — has been the backbone of home baking for well over a century, and for good reason. It is self-scaling. Whether you have three small eggs or four large ones, the ratios stay the same, and so does the texture.

Once you have made it this way a few times, you will stop reaching for a recipe. You will simply put the eggs on the scales and let them tell you what to do. That is the quiet pleasure of a good plain sponge.

Weighing your eggs and doing the sums

Take your eggs out of the fridge half an hour beforehand if you can — they emulsify far more readily at room temperature. Weigh them in their shells and note the number. Three medium eggs usually come in at around 175g; three large ones closer to 200g, which is generous for a two-layer cake but perfect for a deeper tin.

Whatever they weigh, treat that figure as your single unit and match it across the board.

• Butter — unsalted, softened to room temperature but not greasy
• Caster sugar — finer than granulated, so it creams more easily
• Self-raising flour — or plain flour with 2 level tsp baking powder per 100g
• A pinch of fine salt — a small thing that sharpens the finished cake
• A teaspoon of vanilla extract — optional, but kind to the flavour

If your eggs are on the small side and you want a little insurance, add half a teaspoon of baking powder to the flour. Not more: over-leavened sponges rise fast, then collapse into a sad, domed crater.

Creaming, beating and folding

Beat the butter and sugar together until the mixture turns noticeably pale and fluffy. With a hand mixer, this takes four or five minutes; by hand, longer, and your wrist will tell you when it is done. The texture should feel like soft whipped cream, not gritty.

Add the eggs one at a time, beating well between each. If the mixture looks like it is about to curdle, add a spoonful of the weighed flour and carry on. Once the eggs are in, stop using the mixer.

Sift the flour and salt over the top and fold it in with a large metal spoon, cutting down through the middle and turning the bowl as you go. Stop the moment the last streak of flour disappears. A few lumps beaten out now will cost you a tough, rubbery sponge later.

The finished batter should fall slowly from the spoon — a loose dropping consistency. If it sits stubbornly, loosen it with a tablespoon of milk.

Tins, temperatures and the bake

You want two 20cm (8in) sandwich tins, greased and lined at the base with baking parchment. Divide the mixture between them as evenly as you can; weighing the tins is the surest way. Level the tops with the back of a spoon or a palette knife.

Bake at 180°C (160°C fan, gas mark 4) on the middle shelf for 20 to 25 minutes. They are ready when the tops spring back under a light press and a skewer comes out clean. Fan ovens run hot, so if yours is fierce, drop to 150°C fan and give them an extra couple of minutes. Leave them in the tins for five minutes, then turn out onto a wire rack, peel off the paper and let them cool completely. Fill a warm sponge and the jam will soak in and the cream will slide.

Assembling and the heritage grain question

Turn one sponge upside down so you are working on a flat surface. Spread four to six tablespoons of good raspberry jam across it, right to the edges. Keep that layer modest, or the top sponge will slide when you cut it. Add whipped double cream or a light buttercream if you like, though the classic is jam alone. Sit the second sponge on top, press gently, and dust with caster sugar.

This is where heritage grains earn their place. Swap a quarter to a third of the flour for stoneground wholemeal, spelt or emmer and you get a nuttier, more savoury crumb that stands up beautifully to a sharp jam. Two adjustments matter. Wholemeal and stoneground flours absorb more liquid, so add an extra tablespoon or two of milk, and sift the flour first, tipping the bran back in. Spelt has a softer gluten that breaks down more easily, so fold it in with a gentler hand and expect a slightly lower rise. Einkorn is the most fragile of all — use it for half the flour at most.

Start with the equal-weights method and a plain white sponge, and get that right first. Then play. A Victoria sandwich made with good butter, your own scales and a handful of heritage flour is about as fine a thing as a British kitchen can produce.
