Ginger Bars

1 ¾ cups brown sugar

⅔ cup butter

¼ cup molasses

2 teaspoons ground ginger

2 eggs

2 teaspoons vanilla extract

1 cup all-purpose flour

1 cup whole wheat flour

1 teaspoon baking powder

¼ teaspoon baking soda

1 teaspoon salt

Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking pan.

Mash the brown sugar, butter, and molasses together in a bowl with a spoon until the mixture is creamy and thoroughly combined. Mix in the ginger, eggs, and vanilla extract. In a separate bowl, combine the all-purpose flour, whole wheat flour, baking powder, baking soda, and salt. Stir 1/4 of flour mixture into the butter mixture at a time, incorporating each addition before adding the next. Pour the batter into the prepared baking pan.

Bake in the preheated oven until a toothpick inserted into the center comes out clean, 25 to 30 minutes. Let cool before cutting.
