Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

Cream the butter in a mixing bowl.
Add the sugar, corn flour, baking powder, and eggs to the bowl.
Mix until well combined.

Bake

Pour the batter into a greased cake pan.
Bake in a preheated oven at 400°F (200°C) until golden.

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

What each ingredient does

Butter: Adds fat that softens the crumb and carries flavour through the cake.
White sugar: Sweetens the cake and helps it brown as it bakes.
Corn flour: Starch that gives a fine, tender crumb, with little gluten to toughen it.
Baking powder: Releases gas in the batter so the cake rises in the oven.
Eggs: Add structure as they set and help bind the batter.
