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).
Make the batter
Cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sour milk and baking soda.
Melt the Baker's chocolate and mix it into the batter.
Gradually add the flour, mixing until just combined.
Bake
Pour the batter into a greased cake pan and bake for 30-35 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as they set in the oven.
- Flour
- Provides the main structure that sets as the cake bakes.
- Butter
- Adds fat for tenderness and a rich texture.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Baking soda
- Reacts with the sour milk to produce gas that lifts the batter.
- Sour milk
- Supplies moisture and acidity that activates the baking soda.
The step that matters
Gradually add the flour, mixing until just combined. Overmixing flour develops gluten, which makes the cake tough and dense. Stop mixing once the flour is just incorporated to keep the crumb tender.
