Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the sponge
Preheat the oven to 350°F (175°C).
Beat the eggs and sugar together until creamy.
Add the melted butter, flour, and baking powder; stir well.
Spread the mixture on a buttered baking tin.
Bake for 10 to 15 minutes until golden.
Fill and ice
Turn the cake onto a sieve to cool, then cut in half.
Spread one half with crushed raspberries and dredge with caster sugar.
Cover with the other half.
Sift the icing sugar into a bowl, add enough sieved raspberries to flavor and achieve a thick cream consistency.
Pour the icing over the top of the cake and let it set.
Finish
Once set, cut into fancy shapes.
Use white royal icing in a piping bag to decorate as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten with sugar to trap air, giving the sponge its light structure.
- Flour
- Forms the gluten network that sets the sponge's structure as it bakes.
- Butter
- Adds richness and moisture, and a tender crumb to the sponge.
- Baking powder
- Releases gas in the batter, helping the sponge rise in the oven.
- Raspberries
- Add tartness and fruity aroma to the filling and icing.
- Icing sugar
- Dissolves into the raspberry juice to make a thick, sweet icing that sets smooth.
The step that matters
Bake until just golden. Overbaking dries out the thin sponge and makes it brittle, so it will crack when cut in half. Watch the color closely within the 10 to 15 minute window.
