Why it works: Butter and milk 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 ↓
Washington 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. 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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the egg and mix well.
Stir in the sweet milk, baking soda, and cream of tartar.
Gradually add the flour and mix until smooth.
Pour the batter into 2 round cake tins.
Bake and assemble
Bake for 25-30 minutes or until a toothpick comes out clean.
Once cooled, spread apple sauce or your choice of fruit between the layers.
Top the cake with powdered sugar.

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 adds richness and tenderness to the crumb.
- Egg
- Binds the batter and adds structure and moisture as the cake sets.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda, helping the cake rise and stay tender.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
