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 ↓
Devil 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 chocolate mixture
Boil 1 cup sugar, ½ cup milk, and 2 squares of chocolate; set aside to cool.
Make the batter
Cream together 1 cup brown sugar and ½ cup butter.
Add 2 beaten eggs, ½ cup milk, and 1 teaspoon baking soda dissolved in a little hot water.
Mix in 2 cups flour and the cooled boiled mixture.
Bake in layers or a large flat tin at 350°F (175°C).
Make the icing
For icing, beat 1 tablespoon butter until creamy, then add confectioner's sugar until thick enough to spread.
Flavor the icing with vanilla and add chopped nuts if desired.

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 bakes.
- Baking soda
- Reacts with the batter to help the cake rise and turn lighter.
- Flour
- Provides the structure that holds the cake together.
- Chocolate
- Gives the cake its chocolate flavor and deep color.
- Brown sugar
- Adds moisture, sweetness, and a molasses-like depth to the cake.
- Butter
- Adds richness and tenderness to the cake crumb.
The step that matters
Dissolving the baking soda in hot water. Baking soda needs to be fully dissolved and evenly distributed through the batter; clumps can leave bitter, soapy spots and uneven rising.
Swap the nuts
The recipe marks nuts as optional. How well each one fits the dish's main ingredients (sugar, milk, chocolate, butter, egg, flour, vanilla):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Nutsthe original
Fit is the average pairing score against sugar, milk, chocolate, butter, egg, flour, vanilla. Candidates are from the same food group and used in at least 100 recipes.
“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.
