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 ↓
Surprise 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.
Mix the batter
Preheat oven to 350°F (175°C).
In a mixing bowl, cream together butter and sugar until light and fluffy.
Add egg and mix well.
Stir in sweet milk.
In a separate bowl, combine baking soda and cream of tartar.
Add dry ingredients to wet mixture and mix until smooth.
Add flavoring to taste.
Bake
Pour batter into greased cake pan and bake for 25-30 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat for tender texture and rich flavor.
- Sugar
- Sweetens the cake and helps create a tender crumb and browning.
- Egg
- Binds the batter and adds structure as it sets.
- Sweet milk
- Provides liquid that hydrates the flour and keeps the crumb moist.
- Baking soda
- Reacts with an acid to release gas that makes the cake rise.
- Cream of tartar
- Provides acid that reacts with baking soda to leaven the batter.
The step that matters
Cream the butter and sugar until light and fluffy. Beating air into the butter and sugar creates tiny bubbles that help the cake rise and give a fine, even crumb. Under-creamed batter tends to bake up dense.
“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.
