Chocolate Petits Fours

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.

Make the batter

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

  2. Cream the butter and gradually add the sugar.

  3. Beat in the eggs until well combined.

  4. Stir in the melted chocolate, bread crumbs, flour, and vanilla.

  5. Spread the mixture in a shallow baking pan to about ¼ to ⅓ inch thickness.

Bake and shape

  1. Bake until set, then allow to cool in the pan.

  2. Once cool, use a circular cutter to shape into 1-inch rounds.

Assemble

  1. Pair the rounds with white frosting in between and on top.

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

What each ingredient does

Eggs
Bind the batter and help set the structure as it bakes.
Butter
Adds richness and tenderness to the crumb.
Stale bread crumbs
Give body to the batter and help make the cake-like texture.
Melted chocolate
Provides the chocolate flavor and deep color.
Sugar
Sweetens the batter and helps create a tender texture.
Flour
Adds structure so the batter holds its shape when baked.

The step that matters

Spread the mixture to an even thickness. A thin, even layer bakes uniformly and sets without drying out or cooking unevenly at the edges. Uneven thickness gives rounds that bake at different rates and cut unevenly.
