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.
Prepare the cake
Preheat the oven to 350°F (175°C).
In a bowl, combine sugar, butter, milk, flour, and baking powder.
Divide the cake batter into two portions.
Beat the egg yolks and whites separately.
Add the yolks to one portion of the batter and the whites to the other.
Flavor the yellow batter with vanilla and the white batter with lemon.
Pour the batters into separate layer cake tins and bake until golden.
Make the frosting
For the frosting, combine dark brown sugar and white sugar in a saucepan.
In a separate bowl, dissolve Knox Gelatin in ¾ cup warm milk.
Add butter to the gelatin mixture and boil for 5 minutes, stirring frequently.
Flavor with vanilla and beat slightly after removing from heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks and whites add structure and richness to the cake crumb when beaten.
- Flour
- Forms the main structure of the cake batter as it sets in the oven.
- Baking powder
- Releases gas in the batter, helping the layers rise and turn light.
- Butter
- Adds fat for tenderness and flavor in both the cake and the frosting.
- Knox gelatin
- Sets the frosting so it holds its shape once cooled.
The step that matters
Boil the frosting for 5 minutes while stirring. Boiling dissolves the sugars fully and controls how much water evaporates, which sets the final texture. Stirring keeps the mixture from scorching on the bottom of the pan.
