Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Maple 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 batter
Preheat the oven to 350°F (175°C).
In a bowl, mix brown sugar, sour cream, butter, eggs, and vanilla until smooth.
Sift together flour and baking soda, then gradually add to the mixture.
Divide the batter into layers and bake until golden.
Make the filling
For the filling, combine granulated sugar, brown sugar, and cream in a saucepan.
Cook until it reaches a soft ball stage, then beat hard while cooling in cold water.
Assemble
Spread the filling between the layers and on top of the cake.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Adds moisture and a caramel, molasses-like flavour to the cake crumb.
- Sour cream
- Adds moisture and tenderness, and its acidity helps the baking soda react.
- Butter
- Adds fat for richness and a tender crumb.
- Eggs
- Add structure and help bind the batter.
- Flour
- Provides the structure that holds the cake together.
- Baking soda
- Reacts with the acidic sour cream to lift the batter.
The step that matters
Beating the filling while it cools. Sugar syrup cooked to soft ball stage must be beaten as it cools so the sugar forms fine crystals. If it is left to set still, it turns grainy or hardens instead of becoming a smooth, spreadable filling.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, cream, butter, egg, flour):
- Vanillathe original
- Raisinfits about as well
- Coconutfits less well
- Figfits less well
Fit is the average pairing score against sugar, cream, butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
“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.
