Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the sweet milk and mix well.
In a separate bowl, beat the egg whites until stiff peaks form and set aside.
In another bowl, beat the egg yolks and then add to the mixture.
Sift together the flour and baking powder, then gradually add to the wet ingredients.
Gently fold in the beaten egg whites.
Bake and frost
Divide the batter evenly into three greased cake pans.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
Let the layers cool before frosting with boiled icing flavored with Royce's vanilla.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites add lift and airiness, while yolks add richness and tenderness to the crumb.
- All-purpose flour
- Provides the structure that holds the cake's shape as it bakes.
- Baking powder
- Releases gas during baking, helping the layers rise and become light.
- Butter
- Adds fat for a tender texture and rich flavor.
- Sugar
- Sweetens the cake and, creamed with butter, helps trap air for a lighter crumb.
- Sweet milk
- Adds moisture and hydrates the flour to form the batter.
The step that matters
Gently fold in the beaten egg whites. Egg white foam holds the air that lifts the cake. Vigorous stirring knocks that air out, leaving dense layers, so fold gently until just combined.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, butter, milk, egg, flour):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against sugar, butter, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
“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.
