Gingerbread Cake

Preheat oven to 350℉. Grease an 8-inch square baking pan with ½ tablespoon butter.

Pour molasses into a medium bowl and add boiling water. Add flour, baking soda, ginger, cinnamon and salt and stir to combine. Add the remaining 4 tablespoons melted butter and brown sugar; beat well using an electric mixer or manually, about 3 to 4 minutes.

Pour the batter into the prepared pan and bake until a toothpick inserted in the center comes out clean, about 35 minutes. Cut into 9 squares and serve topped with whipped cream, if desired.
