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 ↓
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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the cream and eggs, mixing well.
Gradually add the flour and baking powder, stirring until just combined.
Bake and assemble
Pour the batter into jelly cake pans.
Bake until a toothpick inserted in the center comes out clean.
Layer with cream between the cakes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air, giving the cake a light, tender crumb.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking, helping the cake rise.
- Sugar
- Sweetens the cake and helps trap air when creamed with butter.
- Cream
- Adds moisture and richness to the batter and the filling.
The step that matters
Stirring in the flour and baking powder. Overmixing once flour is added develops gluten, which can make the cake tough and dense. Stir only until the flour disappears into the batter.
