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 ↓
Chocolate 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 cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the sweet milk and beaten eggs, mixing well.
Gradually add the flour and baking powder, stirring until smooth.
Pour the batter into a greased cake pan and bake until a toothpick comes out clean.
Make the filling
For the filling, combine cold water, chocolate, butter, and sugar in a saucepan.
Cook over medium heat for 30 minutes, stirring occasionally.
Let the filling cool, then spread it between the layers of the cake.

Butter and flour 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
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Forms the main structure of the cake crumb.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Butter
- Adds fat for tenderness and richness in the cake and filling.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
The step that matters
Let the filling cool, then spread it between the layers of the cake.. The filling thickens as it cools, so spreading it while hot can make it runny and cause it to slide off the layers. Cooling the cake layers first also keeps the filling from melting into them.
