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 ↓

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 cake batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the eggs, buttermilk, hot water, and dissolved cocoa powder; mix well.
Gradually add the flour and baking soda, mixing until smooth.
Bake the cake
Pour the batter into greased cake pans and bake for 30-35 minutes.
Make the filling and assemble
For the filling, combine sugar, sweet milk, cocoa powder, and butter in a saucepan.
Cook over medium heat until thick, then stir in vanilla extract.
Once the cake is cool, spread the filling between the layers.

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.
- Baking soda
- Reacts with the acidic buttermilk or sour milk to produce gas that lifts the cake.
- Buttermilk or sour milk
- Adds acidity that activates the baking soda and tenderizes the crumb.
- Butter
- Creamed with sugar to trap air and add richness and tenderness.
- Cocoa powder
- Provides chocolate flavor and dark color to the cake and filling.
- All-purpose flour
- Forms the gluten network that gives the cake its structure.
The step that matters
Cook the filling until thick. Sugar and milk must be cooked long enough to thicken into a spreadable filling. Undercooked filling stays runny and soaks into the cake, while overcooking can make it grainy or stiff once it cools.
