Step 1

Preheat oven to 350°F. Line a 9×9-inch baking dish with parchment paper. Set aside.

Step 2

In a large bowl, combine butter and brown sugar. Stir well.

Step 3

Mix in eggs, molasses, and vanilla.

Step 4

In a medium bowl, whisk together the flour, ginger, cinnamon, baking powder, and salt.

Step 5

Gradually stir the flour mixture into the butter and egg mixture until completely combined.

Step 6

Spread the batter evenly into the prepared pan. Bake for 30-35 minutes, or until the edges are set and the center is no longer jiggly. If you are using a 9×13-inch pan, bake for 25-30 minutes.

Step 7

Allow to cool completely before sprinkling with confectioners' sugar. Cut and serve!
