Preheat the oven to 350°F. Prepare a 9x9 inch baking dish by either greasing it with nonstick spray or lining it with parchment paper.
In a medium-sized bowl, combine the flour, salt, baking soda, cinnamon, nutmeg, and cloves. Set this mixture aside.
In a separate bowl, whisk together the coconut oil, dark brown sugar, granulated sugar, eggs, Greek yogurt, pumpkin puree, and vanilla extract.
Gradually add the dry ingredients to the wet mixture, stirring until the batter is just combined.
Pour the batter into the prepared baking dish and bake for 25-28 minutes. Check for doneness by inserting a toothpick into the center of the cake; it should come out clean. Allow the cake to cool completely before cutting and serving.
