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 ↓
Caramel 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).
Dissolve the chocolate in a little hot water.
Make the batter
In a bowl, cream together the butter and powdered sugar.
Add the eggs and sweet milk, mixing well.
In another bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Bake
Pour the batter into prepared cake pans and bake 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
- Eggs
- Bind the batter and add structure as they set in the oven.
- Butter
- Adds fat and richness, and helps trap air when creamed with sugar.
- Powdered sugar
- Sweetens the cake and helps give it a fine, tender crumb.
- Flour
- Forms the main structure of the cake as it bakes.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Chocolate
- Adds chocolate flavour and colour to the batter.
The step that matters
Gradually add the dry ingredients to the wet mixture, stirring until smooth. Adding dry ingredients in portions and mixing only until smooth keeps the batter from becoming overworked. Overmixing develops gluten in the flour, which can make the cake tough and dense.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
