Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a large bowl, beat the butter until creamy.
Gradually add the sugar and continue to beat until light and fluffy.
Add the egg yolks one at a time, mixing well after each addition.
In a separate bowl, combine the corn starch, flour, baking powder, cream of tartar, and baking soda.
Gradually add the dry ingredients to the butter mixture, mixing until just combined.
Bake and frost
In another bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter until no streaks remain.
Pour the batter into a greased cake pan and bake for 25-30 minutes or until a toothpick comes out clean.
For the icing, beat the reserved egg whites until stiff peaks form and frost the cooled cake.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- White sugar
- Sweetens the cake and, beaten with butter, helps create a light, fluffy structure.
- Eggs
- Egg yolks add richness and structure; whipped whites add air that lifts the cake.
- Baking powder
- Releases gas in the batter to make the cake rise.
- Cream of tartar
- Stabilizes whipped egg whites so they hold their peaks.
- Corn starch
- Softens the crumb by diluting gluten, giving a finer, more tender texture.
The step that matters
Folding the egg whites into the batter. Whipped whites hold the air that lifts the cake. Folding gently and only until no streaks remain keeps that air from collapsing, so the cake stays light.
