Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Coffee Cake
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.
Prepare the cake batter
Weigh 3 eggs and use the same weight for butter, castor sugar, and self-raising flour.
Beat the butter until creamy, then add the sugar and the yolks of the eggs (unbeaten). Mix well.
Add the beaten egg whites and mix until smooth.
Sift in the flour while beating continuously.
Add 2 teaspoons of coffee essence and mix well.
Bake and make the cream
Prepare 2 round flat tins by lining them with buttered paper.
Pour the mixture into the prepared tins and bake in a moderate oven at 350°F (175°C).
To make the cream, beat 1 pint of cream with 3 teaspoons of icing sugar and 1 teaspoon of coffee essence until thick.
Once the cakes are completely cool, spread the cream between the two layers.
Glaze and finish
In a soup plate, mix 3 tablespoons of icing sugar and 1 tablespoon of coffee essence with a little boiling water to create a glaze.
Spread the glaze over the top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whole eggs and beaten whites give the cake its structure and lift.
- Butter
- Creamed with sugar, it traps air and gives a tender, rich crumb.
- Castor sugar
- Beaten with butter, it creates air pockets and adds sweetness and browning.
- Self-raising flour
- Its built-in raising agent and gluten set the cake's structure as it bakes.
- Cream
- Whipped to thick, it adds moisture and richness to the filling.
The step that matters
Sift in the flour while beating continuously. Gentle, continuous mixing keeps the batter light; overbeating after the flour is added develops gluten and can make the cake tough.
