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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the cake
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and sugar.
Add the eggs and milk, mixing well.
In another bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Divide the batter into three thin layers and bake until golden.
Make the filling
For the filling, combine 2 cups of sugar, ⅔ cup of milk, and butter in a saucepan.
Boil for 10 minutes, stirring until thickened.
Remove from heat, add vanilla, and let cool slightly.
Assemble
Spread the filling between the layers of cake and on top.

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 and richness to the crumb.
- Butter
- Adds fat for tenderness and flavor in both the cake and the filling.
- Sugar
- Sweetens the cake and, when boiled with milk, thickens into the caramel filling.
- Flour
- Forms the main structure of the cake layers.
- Cream of tartar
- Acidifies the batter and helps stabilize the leavening reaction.
- Baking soda
- Reacts with the acidic cream of tartar to make the layers rise.
The step that matters
Boiling the filling. Sugar and milk must be boiled long enough to thicken into caramel, but overcooking can scorch the sugar or make the filling too hard once cooled. Stirring prevents sticking and burning on the bottom of the saucepan.
