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 ↓

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
Preheat your oven to 350°F (175°C).
Make the batter
In a bowl, cream together the melted butter and sugar.
Add the eggs and mix well.
In another bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, alternating with the milk.
Mix until smooth and pour into a greased baking pan.
Bake
Bake for 25-30 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Melted butter
- Adds fat and richness, giving the cake a tender crumb.
- Sugar
- Adds sweetness and helps the crust brown during baking.
- Eggs
- Add structure as they set, and moisture to the batter.
- Flour
- Forms the main structure that holds the cake together.
- Baking powder
- Releases gas in the batter, making the cake rise.
- Milk
- Adds moisture and loosens the batter for even mixing.
The step that matters
Alternating dry ingredients with milk, then mixing until just smooth. Adding flour makes gluten develop as you mix. Alternating with milk and stopping once smooth keeps the batter from being overmixed, which would make the cake tough and dense.
