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 ↓
Chocolate 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).
Cream together the powdered sugar and butter.
Add the milk, flour, eggs, baking soda, and cream of tartar; mix well.
Pour the batter into a greased cake pan and bake until a toothpick comes out clean.
Make the filling and assemble
For the filling, mix the chocolate, sweet milk, and corn starch in a saucepan.
Boil for 2 minutes, then remove from heat and stir in the vanilla.
Sweeten to taste and spread thickly between the layers of cake.

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 the cake bakes and sets.
- Butter
- Adds fat and tenderness to the crumb and richness to the batter.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter so baking soda can react and lift the cake.
- Corn starch
- Thickens the chocolate filling as it boils.
- Chocolate
- Gives the filling its chocolate flavor and body.
The step that matters
Boil the filling before removing it from heat. Cornstarch only thickens fully when it reaches a boil and its starch granules swell. Stopping early leaves a thin filling that will not hold between the cake layers.
“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.
