Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Birthday Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Pour the batter into a greased cake pan.
Bake and cool
Bake in a moderate oven at 350°F (175°C) until a toothpick comes out clean.
Let the cake cool before icing.

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, giving the cake a light, tender crumb and rich flavour.
- Sugar
- Creamed with butter to hold air bubbles and add sweetness and gentle browning.
- Eggs
- Add structure and moisture, and help bind the batter as they are mixed in.
The step that matters
Adding the eggs one at a time. Adding eggs gradually lets each one emulsify fully into the creamed butter and sugar. Adding them all at once can make the batter curdle and trap less air, which affects the final texture.
