Ingredients
Method
- Preheat oven to 180°C / 160°C fan / Gas 4. Grease and line two 20cm sandwich tins.
- Place all sponge ingredients into a large bowl. Beat with electric whisk for 2–3 minutes until smooth and pale.
- Divide equally between tins — weigh for even layers. Smooth tops. Bake 22–26 minutes until golden, risen, and a skewer comes out clean.
- Cool in tins 5 minutes. Turn out onto a wire rack. Cool completely — at least 45 minutes.
- Place one sponge on serving plate. Spread with jam. Add whipped cream. Place second sponge on top. Dust with icing sugar.
Notes
Butter must be genuinely soft — take out of fridge at least 1 hour before baking.
Weigh batter between tins for perfectly equal layers.
Check at 22 minutes — do not overbake.
Cool completely before filling — warm sponge melts cream.
With whipped cream: refrigerate and eat within 2 days. With buttercream: room temperature up to 3 days.
Unfilled sponge layers freeze for up to 3 months.
