Why it works: Milk and butter 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 ↓
Irving Park 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. 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
Preheat oven to 350°F (175°C).
Make and bake the layers
In a mixing bowl, combine sugar, milk, flour, baking powder, and butter. Mix until smooth and well combined.
Divide batter into four equal portions and pour into greased cake pans.
Bake for 25-30 minutes or until a toothpick comes out clean.
Assemble
Let layers cool before assembling with coconut filling.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the layers rise and turn light.
- Sugar
- Adds sweetness and helps the layers brown and stay tender.
- Butter
- Adds fat for richness and a tender crumb.
- Milk
- Provides moisture that hydrates the flour and forms the batter.
The step that matters
Let layers cool before assembling with coconut filling. Warm layers are fragile and soft, so they can tear or slide when stacked, and filling melts or soaks in. Full cooling lets the crumb firm up so the layers hold their shape.
Swap the coconut
How well each one fits the dish's main ingredients (sugar, milk, flour, butter):
- Vanillafits better
- Raisinfits better
- Figfits about as well
- Coconutthe original
Fit is the average pairing score against sugar, milk, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
