Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Coffee 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 your oven to 350°F (175°C).
Make the batter
In a bowl, cream together the butter and sugar.
Add the eggs and mix well.
Stir in the cold coffee and molasses.
Dissolve the baking soda in a little coffee and add it to the mixture.
Gradually add the flour until well combined.
Bake
Pour the batter into a greased baking pan.
Bake for about 30-40 minutes or until a toothpick comes out clean.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Creams with sugar to trap air and adds richness and tender texture.
- Eggs
- Bind the batter and add structure as the cake sets.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking soda
- Reacts with the acidic molasses to release gas so the cake rises.
- Molasses
- Adds moisture, deep sweetness and a darker color to the cake.
The step that matters
Dissolving the baking soda. Baking soda needs to be fully dissolved and evenly mixed so it reacts uniformly with the acid in the batter; clumps can leave bitter spots and uneven rising.
“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.
