Preheat your oven to 350°F (177°C) and line a 9×9-inch baking dish with parchment paper.

In a large mixing bowl, melt 1 cup of unsalted butter and combine it with 1 ½ cups of light brown sugar until fully incorporated.

Stir in 2 large eggs, 2 tablespoons of molasses, and 1 teaspoon of vanilla extract to the mixture until smooth.

In a separate bowl, whisk together 2 ½ cups of all-purpose flour, 1 tablespoon of ground ginger, 2 teaspoons of cinnamon, 1 teaspoon of baking powder, and ½ teaspoon of kosher salt.

Gradually add the dry ingredients to the wet mixture, gently folding them together until just combined.

Pour the brownie batter into your prepared baking dish, spreading it evenly across the pan.

Bake for 30-35 minutes, testing for doneness with a toothpick.

Allow the brownies to cool completely in the pan, then dust with confectioners’ sugar before slicing.
