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 ↓
Caramel Cake
Ingredients
Directions
The book says “a warm oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Cream together the butter and sugar in a large bowl.
Add the sweet milk and mix well.
Sift in the flour and baking powder, mixing until combined.
Gently fold in the stiffly beaten egg whites.
Pour the batter into jelly cake tins and bake at 350°F (175°C) until golden.
Make the filling
For the filling, combine brown sugar, milk, molasses, and butter in a saucepan.
Add the grated chocolate and bring to a boil, stirring constantly for about 5 minutes.
Remove from heat, add a pinch of baking soda, and let cool.
Once cool, flavor the filling with vanilla and spread between the cake layers.
Optionally, cover the top and sides of the cake with the filling.

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 and add richness and tenderness to the crumb.
- Egg whites
- Stiffly beaten whites trap air, giving the cake lift and a light structure.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas during baking, helping the cake rise.
- Brown sugar
- Adds moisture and a deep, caramel-like sweetness to the filling.
- Grated chocolate
- Melts into the filling, adding bitterness, richness and body.
The step that matters
Boiling the filling while stirring. Stirring constantly keeps the sugars and chocolate from scorching on the bottom of the saucepan, and the boil thickens the filling so it can be spread between the layers.
