Chocolate Wafers

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the dough

  1. Preheat the oven to 400°F (200°C).

  2. In a bowl, cream together the brown sugar, granulated sugar, and butter.

  3. Add the grated chocolate, egg, and vanilla extract; mix well.

  4. Gradually add enough flour to form a stiff dough.

Shape and bake

  1. Roll the dough very thin on a floured surface.

  2. Cut into desired shapes and place on a baking sheet.

  3. Bake in the preheated oven until crisp.

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 the dough cream and hold together.
Brown sugar
Adds sweetness and moisture, and contributes to a chewy-crisp texture.
All-purpose flour
Provides structure, forming the stiff dough that holds the wafer shape.
Egg
Binds the dough and adds richness to the batter.
Grated chocolate
Adds chocolate flavor and fat to the dough.

The step that matters

Roll the dough very thin. Thin dough dries out and crisps during baking, while thick dough stays soft in the centre. Uneven thickness causes uneven browning.
