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 ↓
Velvet 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
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, cream the butter and powdered sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the cold water, baking soda, and cream of tartar until combined.
Gradually add the flour and mix until smooth.
Add flavoring to taste.
Bake
Pour the batter into a greased cake pan and bake for 1 hour.
If desired, add fruit and spice before baking or make a chocolate version by baking as a jelly cake.

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, giving the cake a tender, rich crumb.
- Eggs
- Add structure and richness, binding the batter as the cake sets.
- All-purpose flour
- Provides the main structure that sets the cake as it bakes.
- Baking soda
- Reacts with the acid in cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acidic component that reacts with baking soda to lift the batter.
The step that matters
Adding the eggs one at a time. Eggs added too quickly can break the emulsion of creamed butter and sugar, causing a curdled batter and a denser cake. Mixing well after each egg keeps the batter smooth and evenly aerated.
