Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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 batter
Cream the butter and sugar together.
Add the beaten eggs and mix until light.
Sift the flour and baking powder together.
Add the flour mixture alternately with the milk to the butter mixture.
Bake
Pour into two small layer cake pans.
Bake in a moderate oven at 350°F (175°C) for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, and helps trap air when creamed with sugar.
- Eggs
- Add structure and moisture, and help the batter hold its light texture.
- Baking powder
- Releases gas in the oven, making the cake rise and become light.
- Flour
- Forms the structure that sets the cake as it bakes.
- Fine sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Milk
- Adds moisture and works with the flour to form a smooth batter.
The step that matters
Add the flour mixture alternately with the milk. Adding flour and liquid in alternating portions keeps the batter smooth and well combined. Overmixing once flour is added can develop gluten, which toughens the crumb.
