Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.

In a large bowl, whisk together flour, baking soda, salt, ground ginger, and ground cinnamon.

In another bowl, whisk molasses, brown sugar, eggs, and vegetable oil until smooth.

Gradually add the dry mixture to the wet mixture, stirring gently until fully incorporated.

Pour the batter into the prepared cake pan, spreading it evenly.

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

Let the cake cool in the pan for 10 minutes before transferring it to a wire rack.
