Why it works: Milk and butter 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 ↓
Chocolate Cream Cake Filling
Ingredients
Directions
Make the filling
Melt the chocolate in a saucepan.
In a separate pot, combine sugar and sweet milk, and place over medium heat.
Bring the mixture to a rapid boil, stirring constantly for 2 minutes.
Remove from heat, add flavoring, and beat until stiff enough to spread.
Assemble
Spread the cream on your cake layers quickly, then top with melted chocolate.
For layer cakes, spread cream on all layers at once before adding chocolate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the rich chocolate flavor and color of the filling.
- Granulated sugar
- Sweetens the filling and, when boiled, helps it thicken as it cools and stiffens.
- Sweet milk
- Supplies liquid that dissolves the sugar and forms the body of the cream.
The step that matters
Boiling the sugar and milk. Boiling for the full 2 minutes while stirring dissolves the sugar and brings the mixture to the concentration needed to set. Undercooking leaves it runny; stirring prevents scorching on the bottom of the pot.
