Why it works: Vanilla and cocoa work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 357 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Fudge 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 cake
Cream together the butter and sugar.
Add the melted chocolate and beaten egg, then mix in the milk, salt, and vanilla.
Sift the flour with the baking powder and fold it into the mixture.
Pour the batter into a shallow pan and bake at 350°F (175°C) until done.
Make the icing
For the icing, cream together the confectioners' sugar and butter.
Add the cocoa, vanilla, and hot coffee, mixing until smooth.
Adjust sugar for spreading consistency.

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 form a tender, aerated base for the cake and icing.
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Egg
- Binds the batter and adds structure and richness to the crumb.
- Melted chocolate
- Adds deep chocolate flavor and color to the cake batter.
- Confectioners' sugar
- Dissolves smoothly into the butter to give the icing a spreadable, sweet body.
The step that matters
Sift the flour with the baking powder and fold it in. Folding gently keeps the air from creaming the butter and sugar and the baking powder's gas intact. Overmixing develops gluten, which makes the cake tough and dense rather than tender.
Swap the cocoa
How well each one fits the dish's main ingredients (butter, sugar, chocolate, egg, milk, vanilla, flour):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Cocoathe original
Fit is the average pairing score against butter, sugar, chocolate, egg, milk, vanilla, flour. Candidates are from the same food group and used in at least 100 recipes.
