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 ↓
Plain 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.
Make the batter
Cream the butter and gradually add the sugar.
Add the beaten eggs and flavoring, mixing thoroughly.
Alternately add the flour and milk, sifting the baking powder with the flour. Do not beat after adding flour; stir just enough to combine.
Bake
Pour into loaf or shallow pans and bake at 350°F (175°C) until it shrinks from the sides and springs back when pressed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich texture.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with fat.
- Eggs
- Add structure, richness and moisture to the batter.
- Milk
- Adds moisture and works with the flour to form the batter.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
The step that matters
Do not overmix after adding flour. Once flour meets liquid, gluten begins to form. Overbeating develops too much gluten, making the cake tough and dense instead of tender. Stir only until combined.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
