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 ↓
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
Preheat the oven to 350°F (175°C).
In a bowl, mix powdered sugar, baking powder, flour, and eggs.
Add water and combine until smooth.
Divide the batter into two layers and bake until golden.
Make the cream filling
For the cream filling, heat milk to near boiling.
Mix cornstarch with a little cold milk and add to the hot milk.
In another bowl, combine beaten eggs and sugar, then add to the milk mixture.
Boil until thickened, then cool.
Stir in vanilla and melted butter.
Assemble and serve
Spread the cream filling between the layers and sprinkle powdered sugar on top.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure to the batter and help bind the cake as it bakes.
- Flour
- Forms the main structure of the cake batter.
- Baking powder
- Releases gas during baking so the cake layers rise.
- Cornstarch
- Thickens the milk so the cream filling sets smooth and spreadable.
- Butter
- Adds richness and a soft, tender texture to the cream filling.
- Milk
- Forms the base of the cream filling, which thickens with heat.
The step that matters
Boil until thickened, then cool. Cornstarch only thickens fully once the mixture reaches a boil, and the egg mixture must be cooked through while stirring so it does not scramble. Cooling lets the filling set to a spreadable consistency.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, flour, egg, milk, butter):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against sugar, flour, egg, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
