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.

Prepare

Preheat the oven to 400°F (200°C).

Make the batter

In a bowl, combine molasses, flour, butter, baking soda, and flavoring.
Beat the ingredients together thoroughly.

Bake

Drop spoonfuls of the mixture onto a buttered baking sheet.
Bake for 5 to 6 minutes.

What each ingredient does

Molasses: Adds sweetness, deep flavor, and moisture to the cakes.
Flour: Provides the structure that holds the cakes together as they bake.
Butter: Adds fat for tenderness and richness in the finished cakes.
Baking soda: Reacts with the acidity in molasses to help the cakes rise and brown.
