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 ↓
Birthday Cake with Glaze
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
Sift the sugar, then measure it.
Wash the butter in ice water until it is white and creamy, then dry it with a towel.
Add the butter to the sugar and rub both to a creamy consistency.
Make the batter
Stir in the egg yolks one by one, beating until light and foamy.
Stir in 1 cup of sifted flour.
Add the milk.
Add another cup of sifted flour and mix well.
Stir in the last cup of flour with the baking powder sifted in.
Gently fold in the well-beaten egg whites and the rose water.
Bake and cool
Butter a large round cake tin and line the bottom with paper.
Pour in the mixture.
Bake in a 350°F (175°C) oven for 1 hour.
Test for doneness by inserting a fine broom whisk in the center; it should come out dry.
Let the cake cool partially on a wire rack.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that creams with sugar to give a tender, fine crumb.
- Sugar
- Sweetens the cake and helps trap air when creamed with the butter.
- Eggs
- Yolks add richness and structure; well-beaten whites add lift and a light texture.
- Flour
- Forms the structure that holds the cake's shape as it bakes.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Milk
- Adds moisture and loosens the batter for an even bake.
The step that matters
Gently fold in the beaten egg whites. The whites hold the air that makes the cake light. Stirring or mixing hard knocks out that air, so the cake turns dense and may not rise well.
“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.
