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 ↓
Plain 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.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together.
Beat the egg whites separately, then add the beaten yolks to the mixture.
Melt the chocolate with hot water and thicken with pulverized sugar.
In a separate bowl, mix flour, baking powder, cream of tartar, and baking soda.
Combine the dry ingredients with the butter and sugar mixture, then add the sweet milk.
Marble and bake
Divide the batter in half; to one half, add grated chocolate, molasses, cinnamon, and cloves.
Swirl the two batters together to create a marbled effect.
Pour into a greased cake pan and bake until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the cake's structure as its proteins set during baking.
- Eggs
- Add richness and structure, and help bind the batter together.
- Butter
- Adds fat for tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps keep the crumb tender and moist.
- Baking powder
- Releases gas in the batter so the cake rises.
- Baker's chocolate
- Gives the cake its chocolate flavor and darkens the marbled half.
The step that matters
Combining the flour mixture with the batter. Once flour is wet, gluten begins to form, and overmixing makes the cake tough. Stir just until the dry ingredients are incorporated so the crumb stays tender.
“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.
