Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Chocolate Filling
Ingredients
Directions
Cook the filling
Cut the chocolate into small pieces.
Combine all ingredients in a saucepan and cook over medium heat.
Test the mixture in cold water; when it reaches the soft ball stage, remove from heat.
Cool, beat and spread
Allow to cool, then beat until thick and creamy.
Spread the filling on the cake without stirring after it begins to boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Granulated sugar
- Provides sweetness and, as it cooks and cools, helps set the thick, creamy texture.
- Cream
- Adds moisture and richness, keeping the filling soft and smooth.
- Butter
- Adds fat for a smooth, tender mouthfeel.
- Baker's chocolate
- Adds chocolate flavor and body to the filling.
The step that matters
Remove from heat at the soft ball stage. Sugar concentration rises as the mixture cooks. Removing it at the soft ball point sets the texture: stopping too early leaves the filling loose, while cooking too long makes it stiff and grainy once beaten.
