Preheat the oven to 350 degrees Fahrenheit.
Sift together all your dry ingredients in a medium bowl - the spices, flour, baking soda and salt then set aside.
1 ⅓ Cups + 1 tablespoon all-purpose flour, ½ tablespoon ground ginger, ¼ teaspoon allspice, ¼ teaspoon cloves, ½ teaspoon ground cinnamon, ½ teaspoon ground cardamom, ½ teaspoon freshly ground nutmeg, ½ teaspoon baking soda, Pinch of sea salt
Add all of the rest of the ingredients into a large bowl and whisk to completely combine. Then, add the dry ingredients and mix until smooth.
⅓ Cup + 1 tablespoon canola or grapeseed oil, ⅓ cup brown sugar, ½ cup molasses, ½ cup buttermilk, 1 egg
Add batter into a greased and lined 8inch cake pan and bake for 30 minutes - testing for doneness with a toothpick before removing from the oven.
Allow the cake to cool in the pan for 10 minutes before removing it from the pan and let it cool completely before frosting.
