Ingredients
Method
Prepare
- Heat the oven to 180 C / 350 F. Grease two 20 cm round sandwich tins and line the bases with baking paper.
- Weigh all your ingredients before starting so you can work quickly once the butter is creamed.
Make the batter
- Beat the softened butter and caster sugar together on medium-high speed for 4 minutes until the mixture is pale, fluffy, and doubled in volume.
- Add the eggs one at a time, beating for 30 seconds after each addition. Scrape down the bowl between eggs. Add the vanilla extract with the last egg.
- Sift the flour and salt over the batter. Fold in gently with a large metal spoon using slow figure-eight strokes until no dry flour is visible. Add the milk if the batter looks stiff - it should drop slowly off the spoon.
Bake
- Divide the batter equally between the two prepared tins. Use kitchen scales to confirm equal weights. Smooth the tops lightly with an offset spatula.
- Bake on the middle shelf for 20 to 22 minutes until the sponges are golden and spring back when you press the center lightly.
- Leave in the tins for 5 minutes, then turn out onto a wire cooling rack. Peel off the baking paper and leave to cool completely, about 15 minutes.
Assemble
- Place one sponge layer flat side up on a serving plate. Spread the strawberry jam evenly to within 1 cm of the edge.
- Place the second sponge on top, flat side down, and press gently so the jam just reaches the edge.
- Dust the top with caster sugar through a fine sieve and serve at room temperature.
Notes
For a slightly more tender crumb, swap 20 g of the flour for 20 g of cornflour. The difference is subtle but noticeable in a side-by-side comparison.
