Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Chicago Dessert 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 sugar and flour.
Add the beaten egg yolks and baking powder. Mix well.
Beat the egg whites until stiff peaks form, then fold them into the batter.
Divide the batter into two cake pans and bake until golden.
Make the cream
For the cream, bring 1 cup of milk to a boil.
Mix corn starch with 2 tablespoons of milk until smooth, then add the mixture to the boiling milk.
Stir in the beaten egg, sugar, and lemon or vanilla extract until thickened.
Assemble
Once the cakes are cool, layer them with the cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air when whipped, lifting the batter, and yolks add richness and structure.
- Flour
- Forms the cake's structure once mixed with the wet ingredients and heat sets it.
- Baking powder
- Releases gas in the batter, helping the cakes rise and turn light.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Milk
- Adds moisture and, with corn starch, thickens the cream.
- Corn starch
- Thickens the cream as it heats, giving it a smooth, set texture.
The step that matters
Stirring the cream while it thickens. Corn starch must be fully smoothed into cold milk before it meets the boiling milk, otherwise it clumps. Once heated, the starch swells and thickens the cream, so it needs constant stirring to keep it smooth and avoid scorching.
