Ingredients

Directions

The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

Cream the butter in a bowl.
Add the sugar and mix well.
In a separate bowl, combine the flour and baking powder, then add to the butter mixture.
Beat the eggs well and fold them into the mixture.

Bake

Pour the batter into a buttered tin.
Bake at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour: Forms the structure that holds the cake's crumb together as it bakes.
Baking powder: Releases gas in the batter so the cake rises and becomes light.
Butter: Adds fat for a tender texture and rich flavour.
Sugar: Sweetens the cake and helps create a soft, tender crumb.
Eggs: Add structure, moisture and richness to the batter as they set.
