In a microwave-safe mug, whisk together the flour, brown sugar, baking powder, baking soda, ground ginger, ground cinnamon, ground cloves, and a pinch of salt.
Add the molasses, milk, melted butter, and vanilla extract to the mug. Stir until the batter is smooth and well combined.
Microwave the mug on high for 1 minute and 30 seconds to 2 minutes, or until the cake has risen and set in the middle.
Allow the mug cake to cool for a minute or two before topping it with whipped cream or a scoop of vanilla ice cream, if desired.
Serve immediately and enjoy your warm and comforting Gingerbread Mug Cake!
