Why it works: Vanilla and milk 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 ↓
French Cream 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 layers
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the beaten egg yolks and water. Mix well.
Sift together the flour and baking powder.
Add the sifted mixture to the batter.
Fold in the beaten egg whites and vanilla extract.
Pour the batter into layers.
Bake until golden.
Make the filling and assemble
For the filling, heat the sweet milk and sugar in a saucepan.
Add the butter, eggs, and dissolved corn starch.
Cook until thick.
Spread the filling between the cooled layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness to the cake and fat to the filling.
- Eggs
- Egg whites add lift when folded in, and yolks and whole eggs help bind and thicken the batter and filling.
- Flour
- Forms the structure of the cake layers as its proteins set during baking.
- Baking powder
- Releases gas in the batter, helping the layers rise and become light.
- Corn starch
- Thickens the filling as it heats, giving it a smooth, spreadable body.
- Sugar
- Sweetens the cake and filling and helps the layers brown.
The step that matters
Cook the filling until thick. Corn starch only thickens once it is heated enough for its granules to swell and gelatinize. Stopping early leaves a runny filling that will not hold between the layers, while overcooking can make it stiff or cause it to scorch on the bottom of the pan.
