Preheat oven to 375°F/190°C. Grease a muffin pan or line with muffin liners.
In a large bowl whisk together flour, baking soda, cinnamon, ginger, nutmeg, and salt.
Divide batter evenly in a silicon muffin pan or a cupcake pan with paper liners.. Bake for 16-22 minutes until a toothpick inserted into the center of the muffin comes out clean. Allow to cool for 5 minutes in the pan, then transfer to a wire rack to cool completely.
