Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
White Layer 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).
Sift the flour and baking powder together.
Cream the butter and sugar until light and fluffy.
Add the water and flour alternately, mixing well after each addition.
Stir in the flavoring and the beaten egg whites.
Divide the batter into two greased cake pans and bake until golden.
Make the filling and assemble
Boil the heavy cream with cornstarch, egg yolks, chopped almonds, and sugar until thick, stirring constantly.
Spread the filling between the layers.
Frost the top.
Garnish with split almonds.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb and flavor.
- Eggs
- Egg whites add structure and lift; yolks add richness and help the filling set.
- Flour
- Forms the cake's structure as its proteins set during baking.
- Sugar
- Sweetens the cake and helps it brown while tenderizing the crumb.
- Heavy cream
- Provides fat and moisture, making the filling smooth and rich.
- Almonds
- Add nutty aroma and texture to the filling.
The step that matters
Boil the filling until thick, stirring constantly. The cornstarch and egg yolks thicken the cream as they heat. Stirring prevents scorching on the bottom and keeps the yolks from clumping, giving a smooth, evenly set filling.
“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.
