Preheat your oven to 425°F (220°C) and line a muffin tin with paper liners. In a large bowl, combine the all-purpose flour, whole wheat flour, brown sugar, baking soda, cinnamon, ginger, and salt.
Bake the muffins in the preheated oven for 7 minutes, then reduce the heat to 350°F (180°C) and bake for 9-11 minutes. Allow the muffins to cool in the tin for 5 minutes, then transfer them to a wire rack to cool completely.
