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 ↓
Sandwich 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
Preheat the oven to 350°F (175°C).
In a bowl, rub the butter into the flour.
Make and bake the cake
Add the sugar, egg, baking powder, and milk, and mix until combined.
Pour the batter into two greased cake pans.
Bake until a toothpick inserted in the center comes out clean.
Assemble
Let the cakes cool, then spread jelly on one layer and stack the other on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Egg
- Binds the batter and adds structure and richness as it sets.
- Butter
- Adds fat for tenderness and flavor, and coats the flour to limit gluten toughness.
- Milk
- Adds moisture that hydrates the flour and helps form the batter.
- Granulated sugar
- Sweetens the cake and helps keep its crumb tender and moist.
The step that matters
Baking until a toothpick comes out clean. Baking until the center is set matters because underbaked batter stays wet and can collapse or sink as it cools, while overbaking dries the crumb.
“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.
