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 ↓
Black 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the sweet milk and eggs, mixing well.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture.
Make the chocolate filling
In a double boiler, combine the chocolate, sweet milk, sugar, and egg yolk; boil until thick.
Fold the chocolate mixture into the cake batter.
Bake
Pour the batter into layers or a bar pan.
Bake until a toothpick inserted comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Eggs
- Add structure and richness, helping the batter bind and set during baking.
- Butter
- Adds fat for tenderness and flavor in the crumb.
- Sugar
- Sweetens the cake and helps brown the crust and keep the crumb tender.
- Baking powder
- Releases gas that makes the cake rise and become light.
- Chocolate
- Gives the cake its chocolate flavor and deep color.
The step that matters
Boil the chocolate mixture until thick. Egg yolk thickens when heated but can scramble if it boils too hard or too long. Cook gently and stir constantly so the mixture becomes smooth and thick rather than grainy.
“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.
