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 ↓

Make the filling

Stir in 1 cup of scalded milk and cook for 10 minutes, stirring occasionally.

Add the cooled mixture, 1 teaspoon of vanilla extract, and 1½ squares of melted chocolate.
Spread the frosting when cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the cooked milk mixture so it sets into a firm, spreadable filling.
- Egg
- Adds richness and helps bind the cooked mixture into a smooth custard-like texture.
- Milk
- Forms the liquid base that the flour and egg thicken into the filling.
- Butter
- Adds fat and creaminess, giving the frosting its smooth, rich body.
- Powdered sugar
- Sweetens the frosting and helps it hold a smooth, spreadable consistency.
- Chocolate
- Gives the frosting its chocolate flavour and deepens its colour.
The step that matters
Cool the cooked mixture before adding it to the butter. If the cooked mixture is still warm, it can melt the butter and make the frosting greasy and loose instead of light and spreadable.
