Why it works: Milk and butter 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 ↓
Chocolate 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 chocolate
Break chocolate into small pieces and place in a double boiler over low heat.
Add ½ cup sweet milk and stir until thick, then remove from heat and let cool.
Make the batter
In a bowl, mix 1 cup sugar, ½ cup butter, and 1 cup milk until well combined.
In another bowl, combine 3 cups flour and 2 heaping teaspoons baking powder.
Add the beaten eggs to the butter mixture, then gradually mix in the flour mixture.
Fold the cooled chocolate mixture into the batter.
Bake
Pour the batter into a greased cake pan and bake at 350°F (175°C) 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
- Flour
- Provides the starch and gluten network that gives the cake its structure.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Baking powder
- Releases gas in the batter, causing the cake to rise as it bakes.
- Sugar
- Sweetens the cake and helps keep the crumb moist and tender.
- Chocolate (in the method)
- Gives the cake its chocolate flavour and deep colour.
The step that matters
Mixing in the flour mixture. Once flour is added, overmixing develops too much gluten, which makes the cake tough and dense. Mix just until the flour disappears into the batter.
