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 ↓
Ice Cream 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together in a bowl.
Add the milk and flavoring, mixing well.
Sift in the flour, cornstarch, and Magic Baking Powder, and mix until combined.
Gently fold in the beaten egg whites until just incorporated.
Bake and cool
Pour the batter into a square pan and bake until golden.
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
- Egg whites
- Whipped whites trap air, helping the cake rise and turn light and airy.
- Magic baking powder
- Releases gas when heated, lifting the batter so the cake rises.
- Butter
- Adds fat that softens the crumb and gives a rich, tender texture.
- Sugar
- Sweetens the cake and helps creaming trap air for a lighter texture.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Cornstarch
- Lightens the crumb and makes the cake more tender than flour alone.
The step that matters
Folding in the egg whites. Egg whites hold air only when whipped, and overmixing deflates them. Folding gently and stopping once just combined keeps the batter light so the cake rises well.
