Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, mix sugar, egg, melted butter, and sweet milk.
Sift together flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, stirring well.
Pour the batter into a greased cake pan.
Bake
Bake for 25-30 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake's shape as it bakes.
- Baking soda
- Reacts with acidic ingredients to release gas, helping the cake rise.
- Cream of tartar
- Acidic powder that stabilises the leavening reaction and adds a tender crumb.
- Egg
- Binds the batter and adds structure and richness as it sets.
- Melted butter
- Adds fat for a tender texture and moist crumb.
- Sugar
- Sweetens the cake and helps it brown lightly in the oven.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding dry ingredients slowly and stirring only until combined keeps the batter smooth and prevents overmixing. Overmixing develops gluten, which can make the cake tough and dense.
