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 ↓
Jelly or 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 batter
Preheat the oven to 350°F (175°C).
In a bowl, cream the butter and sugar together.
Add the eggs and milk, mixing well.
In a separate bowl, combine the flour, baking powder, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Bake the cake
Pour the batter into jelly tins and bake until a toothpick comes out clean.
Make the chocolate filling
For the chocolate, combine the grated chocolate, ½ cup milk, and ½ cup sugar in a saucepan.
Heat until just boiling, then add the corn‑starch and stir until thickened.
Remove from heat and stir in the vanilla.
Assemble
Once the cake is cool, spread the chocolate mixture between the layers and dust the top with powdered sugar.

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 they set during baking.
- Butter
- Adds richness and tenderness through fat coating the flour.
- Sugar
- Sweetens the cake and helps give it a tender, browned crumb.
- Flour
- Forms the main structure of the cake as its proteins set.
- Baking powder
- Releases gas in the batter to help the cake rise.
- Corn-starch
- Thickens the chocolate mixture into a spreadable filling.
The step that matters
Heat the chocolate filling until thickened. Cornstarch thickens only when the mixture reaches a boil and is stirred; stopping early leaves the filling runny, while overcooking can make it stiff or gummy.
