Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Birthday 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.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
In another bowl, combine the flour, baking soda, and cream of tartar (or baking powder).
Gradually add the dry ingredients to the wet mixture, alternating with the milk.
Stir in the lemon and vanilla extracts.
Bake
Pour the batter into a greased cake pan and bake for 30-35 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
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Butter
- Adds fat for richness and tenderness, and traps air when creamed with sugar.
- Eggs
- Provide structure as they set and add moisture and richness to the batter.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with acidic ingredients to produce gas that helps the cake rise.
- Milk
- Adds moisture and helps the batter come together into a smooth mixture.
The step that matters
Alternating dry ingredients with milk. Adding the dry ingredients gradually and alternating with milk keeps the batter smooth and prevents overmixing, which would toughen the cake by overdeveloping gluten in the flour.
