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 ↓
Cream to Spread Between Layers
Ingredients
Directions
Make the custard
In a bowl, mix ½ cup sugar and 2 tablespoons flour until combined.
Stir this mixture into 1 cup of boiling milk until it thickens.
Make the cake batter
In another bowl, cream together ¾ cup sugar and butter until fluffy.
Add 1 egg or 2 egg whites and ⅔ cup milk, mixing well.
Gradually add 1½ cups flour and 2 teaspoons baking powder, stirring until smooth.
Make the filling and bake
For the filling or frosting, combine 2 cups brown sugar, 1 cup sweet cream, and butter.
Boil this mixture until thick, then stir in ⅔ cup milk and 1 egg yolk if desired.
Bake the cake in flat tins or as two layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides structure as it sets around the egg and milk when the cake bakes.
- Eggs
- Add structure and richness, helping the batter bind and set during baking.
- Baking powder
- Releases gas when heated, helping the cake batter rise and become light.
- Butter
- Adds fat for tenderness and richness, and helps the creaming step trap air.
- Brown sugar
- Adds sweetness and moisture, and deepens flavour in the filling or frosting.
- Milk
- Adds moisture and helps the batter and the boiled filling become smooth and tender.
The step that matters
Boil the filling until thick. Sugar-rich mixtures can scorch or turn grainy if overheated, and they only thicken properly when cooked long enough to reach the right concentration. Stir steadily and judge by thickness, not time alone.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, flour, milk, butter, egg, cream):
- Almondfits better
- Pistachiofits about as well
- Chestnutfits about as well
- Walnutthe original
Fit is the average pairing score against sugar, flour, milk, butter, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
