Preheat the oven to 350(f) degrees. Grease & line a standard loaf pan.
In a large mixing bowl sift together the flour, baking soda, salt, ginger, nutmeg, cloves, cardamom & black pepper.
In a separate large mixing bowl whisk together the pumpkin, brown sugar, oil, eggs, vanilla & yogurt.
Add the dry ingredients to the wet ingredients & beat until smooth, about 60 seconds.
Transfer to the prepared loaf pan & sprinkle with pumpkin seeds.
Bake for 35 to 45 minutes, until the top bounces back to touch. Let cool completely before slicing.
