Dark Chocolate 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 the oven to 350°F (175°C).

  2. Cream the butter and sugar together until light and fluffy.

  3. Add the beaten eggs and mix well.

Make the batter

  1. In a separate bowl, combine the flour, cream of tartar, and baking soda.

  2. Gradually add the dry ingredients to the butter mixture, alternating with the sweet milk.

  3. Dissolve the chocolate in a small amount of the cake mixture, then add it back to the main batter.

  4. Mix well and add vanilla extract to taste.

Bake

  1. Pour the batter into a greased cake pan and 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

Butter
Adds fat and richness, and helps trap air when creamed with sugar for a tender crumb.
Eggs
Provide structure and moisture, binding the batter as they set in the oven.
Sugar
Sweetens the cake and helps create a light texture when creamed with butter.
Flour
Forms the main structure of the cake as its proteins set during baking.
Baking soda
Reacts with the acid in cream of tartar to produce gas that makes the cake rise.
Chocolate
Adds chocolate flavor and color to the cake.

The step that matters

Dissolving the chocolate. Chocolate or cocoa dissolves best in a small amount of batter first, so it blends evenly without lumps before being folded into the main batter.
