Why it works: Vanilla and banana are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,430 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Cream Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Combine sugar and butter in a mixing pan.
Let the mixture soften in a 400°F oven for about 1 minute.
Remove from oven and beat for about 2 minutes.
Whip in the beaten egg yolks.
Add the milk, flour, baking powder, and vanilla, and mix until smooth.
Bake
Bake the batter in 3 layers at 350°F until golden.
Fill and garnish
Whip the pastry cream.
Mix in the sugar and vanilla.
Spread the filling between the layers and on top.
Garnish with sliced bananas.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the starch and gluten network that gives the cake its structure.
- Eggs
- Egg yolks add richness and help bind and set the crumb.
- Butter
- Adds fat for tenderness and a richer flavor in the crumb.
- Baking powder
- Releases gas during baking so the layers rise and become light.
- Milk
- Supplies moisture that hydrates the flour and keeps the crumb soft.
- Sugar
- Adds sweetness and helps the layers brown as they bake.
The step that matters
Bake the layers until golden. Thin layers dry out quickly once the starch has set, so pulling them when golden, before they darken further, keeps the crumb moist and prevents a bitter, browned edge.
