Why it works: Vanilla and chocolate are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Devils' Food 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.
Prepare
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Make the batter
Melt the Baker's chocolate and mix it into the batter.
In a separate bowl, combine the flour and baking soda.
Gradually add the flour mixture to the batter, alternating with the buttermilk.
Fill the cup with boiling water and stir it into the batter last.
Pour the batter into a greased 2-inch square pan.
Bake and serve
Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
Let cool, then ice with chocolate icing and serve in blocks.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Sugar
- Creamed with butter to trap air, and it adds sweetness and helps keep the crumb moist.
- Eggs
- Add structure and richness, and help bind the batter.
- Buttermilk
- Its acidity reacts with the baking soda and tenderizes the crumb.
- Baking soda
- Reacts with the acidic buttermilk to release gas, helping the cake rise.
- Butter
- Adds fat for a tender texture and rich flavor.
The step that matters
Adding the flour mixture with the buttermilk. Alternating flour and buttermilk in small additions and mixing just until combined keeps the batter smooth. Overmixing develops too much gluten, which makes the cake tough and dense.
