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 batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter. Add the eggs and mix well. Stir in the sweet milk.
In another bowl, combine the flour and baking powder. Gradually add the dry ingredients to the wet mixture.
Melt the chocolate and let it cool, then stir it into the batter.
Bake and finish
Pour the batter into prepared cake pans and bake until a toothpick comes out clean.
Once cooled, layer the cakes and frost with white icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the batter and helps it cream with butter to trap air for a lighter crumb.
- Butter
- Adds fat for tenderness and flavor, and creaming with sugar traps air in the batter.
- Eggs
- Add structure and richness, and help bind the batter as it bakes.
- Flour
- Forms the main structure of the cake once it sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Cake chocolate
- Adds chocolate flavor and some richness to the batter.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in portions and mixing only until combined keeps the batter smooth and limits gluten development, which would otherwise make the cake tough.
