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 ↓
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, beat the eggs and sugar until well combined.
Add the flour, baking powder, and cold water, then mix until smooth.
Pour the batter into a small tin.
Bake until golden.
Make the custard
For the custard, boil the sweet milk in a saucepan.
In a separate bowl, mix the cornstarch with ½ cup milk until smooth.
Once the milk boils, stir in 1 cup sugar and the cornstarch mixture slowly.
Add the beaten eggs and ½ cup butter, then stir until dissolved.
Assemble and finish
Split the cake while warm to fill with custard.
Fill the split cake with custard.
Top with white icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and enrich the custard, helping it set and giving structure.
- Flour
- Provides the main structure of the cake as it sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Cornstarch
- Thickens the custard so it holds its shape when filled into the cake.
- Butter
- Adds richness and a smooth texture to the custard.
- Sugar
- Sweetens the cake and custard and helps tenderize the crumb.
The step that matters
Stir the cornstarch mixture into the boiling milk slowly. Adding the cornstarch slurry slowly while the milk is boiling and stirring constantly prevents lumps and lets the starch disperse evenly, so the custard thickens smoothly.
“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.
