Sponge Molasses Cake

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

  1. Preheat your oven to 350°F (175°C).

Make the batter

  1. In a large bowl, mix the shortening and molasses until well combined.

  2. Dissolve the baking soda in the boiling water and add it to the mixture.

  3. Gradually stir in the flour until the batter is smooth.

Bake

  1. Pour the batter into a greased cake pan and bake for about 30-40 minutes or until a toothpick comes out clean.

What each ingredient does

Molasses
Adds sweetness, dark color, and a moist, deep flavor to the cake.
Flour
Provides structure as the batter sets in the oven.
Baking soda
Reacts with the molasses and hot water to produce gas that lifts the batter.
Shortening
Adds fat that tenderizes the crumb and carries flavor.

The step that matters

Adding the baking soda mixture. Baking soda must be fully dissolved in the boiling water before it goes in, so it disperses evenly. Uneven distribution can leave pockets that are bitter or soapy and an uneven rise.
