Preheat the oven to 350 degrees. Line a muffin tin with paper liners or grease and flour an 8-inch square baking dish.
In a blender, combine the molasses, maple syrup, applesauce and coconut oil. Blend until smooth.
In a large bowl, sift together the flour, baking soda, sea salt and spices.
Pour the wet ingredients into the dry and mix until just combined. Stir in the hot water. Pour into the prepared pan.
Bake 20-25 minutes for muffins or 35-50 minutes (ovens vary wildly) for an 8-inch cake, until a cake tester inserted in the center comes out clean. Allow to cool before serving. Sift powdered sugar over cake, if desired.
