Ingredients

1  1/4 cups packed dark-brown sugar 

3/4 cup unsulfured molasses 

1/2 cup (1 stick) unsalted butter 

1 tablespoon ground cinnamon 

1 tablespoon ground ginger 

1/2 teaspoon coarse salt 

1 1/4 cups milk 

1 tablespoon baking powder 

6 1/2 cups all-purpose flour 

Preparation

Combine brown sugar, molasses, butter, spices, and salt in a medium saucepan over low heat, stirring with a wooden spoon, until sugar is dissolved, about 10 minutes. Stir in milk. Remove from heat, and let cool.

Pour milk mixture into a mixing bowl; add baking powder and flour. With an electric mixer, and beginning on low speed and increasing to medium, beat until well combined. Divide dough in half; shape into disks. Wrap in plastic, and refrigerate overnight. Dough can be frozen up to 1 month; thaw in the refrigerator before using.
