Old Fashioned Layer 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 the cakes

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

  2. In a large bowl, cream together the butter and sugar until light and fluffy.

  3. Add the eggs one at a time, mixing well after each addition.

  4. Gradually add the flour and baking powder, alternating with the sweet milk, and mix until smooth.

  5. Divide the batter into three equal parts.

  6. To one part, add the molasses and spices, mixing in a little more flour if needed.

  7. Pour the plain batter into two greased cake pans and the spiced batter into one.

Bake and cool

  1. Bake for 25-30 minutes or until a toothpick inserted comes out clean.

  2. Let the cakes cool before frosting.

Make the frosting and assemble

  1. For the frosting, beat the egg whites until stiff peaks form, then gradually add the sugar.

  2. Fold in the grated lemon and juice, then spread between the layers and on top of the cake.

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

What each ingredient does

Butter
Creams with sugar to trap air, giving the cake a tender, fine crumb.
Eggs
Provide structure and richness, binding the batter as the cake sets.
All-purpose flour
Builds the cake's structure as its proteins set during baking.
Baking powder
Releases gas in the batter so the layers rise light and open.
Molasses
Adds moisture, deep sweetness, and browning to the spiced layer.
Egg whites
Whipped into stiff peaks to form a light, airy frosting that holds its shape.

The step that matters

Beating the egg whites for the frosting. Egg whites must reach stiff peaks before the sugar is added gradually; under-whipped or greasy whites will not hold air, leaving a runny frosting. Any trace of yolk or fat prevents whipping.

Swap the allspice

How well each one fits the dish's main ingredients (butter, sugar, egg, flour, milk, molasses, cinnamon):

  1. Nutmegfits better
  2. Cardamomfits about as well
  3. Clovefits about as well
  4. Allspicethe original

Fit is the average pairing score against butter, sugar, egg, flour, milk, molasses, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
