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 in a large bowl.
Gradually add the sugar while beating constantly.
Separate the eggs and beat the yolks until light.
Add the yolks to the butter and sugar mixture and beat again.
Stir in the milk.
Sift in the flour and beat until perfectly smooth.
Add the flavoring.
Beat the egg whites until very stiff.
Gently fold in the egg whites and baking powder until well mixed.
Bake
Pour the batter into a greased cake pan and bake at 350°F (175°C) for about 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cupcake a tender, rich texture.
- Sugar
- Sweetens the batter and helps hold air when creamed with butter.
- Eggs
- Yolks add richness and structure; whites, beaten stiff, add lift and airiness.
- Flour
- Forms the structure that sets the crumb as the cupcake bakes.
- Baking powder
- Releases gas in the batter, causing it to rise during baking.
- Milk
- Adds moisture and loosens the batter to a pourable consistency.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold the air that lifts the batter. Overmixing or deflating them while folding makes the cupcake dense and heavy, so fold gently until just combined.
