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 ↓
Nut Layer 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.
Make the batter
Preheat the oven to 350°F (175°C).
Cream together the butter and sugar in a bowl.
Add the milk, yolks of the two eggs, and the beaten white of one egg, then mix the mixture well.
Sift in the flour and baking powder, stirring until combined.
Divide the batter into two bowls.
In one bowl, add chocolate and vanilla.
In the other bowl, add lemon extract.
Pour the chocolate batter into one pan.
Pour the lemon batter into two other pans.
Bake
Bake until a toothpick comes out clean, about 25-30 minutes.
Make the filling
Whip the cream until thick.
Fold in the chopped walnuts and sugar.
Assemble and finish
Spread the walnut cream between the layers of cake.
Top with the reserved egg white icing and sprinkle shredded coconut over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the main structure that holds the cake's crumb together as it bakes.
- Eggs
- Add structure and moisture, and help the batter set as it bakes.
- Butter
- Adds richness and a tender crumb to the cake.
- Baking powder
- Releases gas during baking, helping the layers rise.
- Heavy cream
- Whipped into a thick filling that keeps the layers moist.
- Walnuts
- Add crunch and a nutty texture to the cream filling.
The step that matters
Bake until a toothpick comes out clean. Egg and flour proteins set as the cake bakes. Underbaking can leave the layers wet and collapsing, while overbaking dries the crumb, so checking for doneness matters.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, milk, flour, butter, egg, cream, chocolate):
- Almondfits better
- Hazelnutfits about as well
- Pistachiofits about as well
- Walnutthe original
Fit is the average pairing score against sugar, milk, flour, butter, egg, cream, chocolate. Candidates are from the same food group and used in at least 100 recipes.
