Ingredients

1/2 cup (1 stick) unsalted butter, plus more for pan 

1 1/2 cups all-purpose flour 

1/2 cup packed light-brown sugar 

1 1/2 teaspoons ground ginger 

1 teaspoon baking powder 

1/4 teaspoon salt 

1/8 teaspoon black pepper 

1/8 teaspoon ground clove 

1/2 cup water 

1/2 cup molasses 

1 large egg, lightly beaten 

2 ounces bittersweet chocolate, melted and slightly cooled 

Preparation

Preheat oven to 325 degrees. Butter an 8-inch square pan. In a bowl, combine flour, brown sugar, ginger, baking powder, salt, pepper, and cloves.

Melt the butter in the water in a small saucepan over medium heat, and stir mixture into the dry ingredients until smooth. Stir in molasses and egg.

Pour half the batter into prepared pan. With a spoon, drizzle half the chocolate over the batter. Pour remaining batter on top, and drizzle the remaining chocolate over the batter in a decorative pattern.

Bake the cake until a toothpick inserted in the center comes out clean, about 30 minutes.
