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 the batter
Preheat the oven to 350°F (175°C).
Cream the butter and powdered sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Sift together the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the butter mixture, alternating with the cold water. Mix until smooth and well combined.
Bake
Pour the batter into a greased cake pan.
Bake for 1 hour or until a toothpick inserted in the center comes out clean.
Add fruit and spices if desired, or bake as a chocolate cake by using chocolate in the batter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich texture.
- Powdered sugar
- Creaming with butter helps create a light, fluffy structure and adds sweetness.
- Eggs
- Add structure and richness, and help bind the batter as it sets in the oven.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking soda
- Reacts with the acid in cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acidic ingredient that reacts with baking soda to help the cake rise and stay tender.
The step that matters
Gradually add the dry ingredients, alternating with the cold water. Adding dry ingredients in portions and alternating with liquid keeps the batter smooth and evenly hydrated. Overmixing once flour is added develops gluten, which can make the cake tough.
