Quick Coffee Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

Preheat the oven to 350°F (175°C).

Make the batter

In a bowl, mix the flour, baking powder, sugar, and salt.
Add the melted butter, egg, and enough sweet milk to create a thin batter.
Pour the batter into a greased pan.

Top and bake

Sprinkle ½ cup of sugar and cinnamon on top.
Bake for 25-30 minutes or until golden brown.

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

What each ingredient does

All-purpose flour: Provides the main structure that sets as the cake bakes.
Baking powder: Releases gas in the batter, helping the cake rise and turn light.
Egg: Adds structure and helps bind the batter together.
Melted butter: Adds fat for a tender crumb and rich flavor.
Sugar: Adds sweetness and helps the top brown as it bakes.
