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 ↓
Marshmallow 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the cake
Preheat your oven to 350°F (175°C).
Cream together 1 ½ cups sugar and ½ cup butter until light and fluffy.
Add 1 cup milk, ½ cup cornstarch, 1 teaspoon baking powder, and 2 cups flour. Mix until smooth.
In a separate bowl, beat the whites of 6 eggs until stiff peaks form. Gently fold the egg whites into the batter.
Pour the batter into a greased cake pan and bake for 25‑30 minutes or until a toothpick comes out clean.
Make the filling
For the filling, combine 1 ½ cups sugar with enough water to moisten and boil until it forms a string. Drop in 8 fresh marshmallows and let them dissolve.
Pour the syrup over the stiffly beaten whites of 2 eggs and beat until stiff.
Assemble
Spread the filling between the layers of the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, creaming with sugar traps air for a tender crumb.
- Egg whites
- Whipped to stiff peaks, they lighten the batter and give the cake its rise and structure.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Sugar
- Sweetens the cake and helps create a tender, fine-textured crumb when creamed with butter.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Marshmallows
- Dissolve into the syrup, giving the filling its soft, light, sweet body.
The step that matters
Folding the beaten egg whites into the batter. Egg whites hold air only while stiff; overmixing or stirring vigorously knocks the air out, so the cake rises less and turns dense. Fold gently and quickly.
