Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Dabk 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 dark brown sugar and butter.
Add the eggs and sweet milk, mixing well.
Gradually stir in the flour.
In a separate saucepan, combine the grated chocolate, milk, dark brown sugar, and egg. Cook over low heat, stirring until smooth, then add vanilla.
Mix this chocolate mixture into the first batter. Sprinkle baking soda over the mixture and stir well.
Bake and frost
Pour the batter into prepared cake pans and bake until a toothpick comes out clean.
For the frosting, boil sugar and milk for eight minutes. Beat the frosting until light and fluffy with a fork.
Spread frosting between the layers of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and add richness and tender texture.
- Eggs
- Bind the batter and add structure and moisture as the cake sets.
- Flour
- Forms the cake's main structure as its proteins set during baking.
- Baking soda
- Reacts with acidity in the batter to produce gas that helps the cake rise.
- Dark brown sugar
- Adds moisture, sweetness and a deeper caramel flavor to the cake.
- Grated chocolate
- Supplies chocolate flavor and color to the batter.
The step that matters
Sprinkle baking soda over the mixture and stir well. Baking soda needs an acid in the batter to react and release gas. Stirring it in evenly keeps the rise uniform, while clumps can leave bitter spots or uneven holes.
