01 - Preheat the oven to 350°F. Grease a 2-quart baking dish or six individual ramekins with butter or cooking spray.
02 - In a large mixing bowl, whisk together the pumpkin purée, eggs, whole milk, heavy cream, brown sugar, maple syrup, and vanilla extract until completely smooth and well incorporated.
03 - In a separate medium bowl, sift together the all-purpose flour, baking powder, salt, ground cinnamon, ground ginger, ground nutmeg, and ground cloves to ensure even distribution.
04 - Gradually add the dry ingredient mixture to the wet ingredients, whisking continuously until fully combined and no lumps remain. The batter should be smooth and thick.
05 - Pour the batter evenly into the prepared baking dish or distribute among the six ramekins, filling each about three-quarters full.
06 - Place the baking dish or ramekins in a larger roasting pan. Carefully pour hot water into the roasting pan until it reaches halfway up the sides of the baking vessel, creating a gentle water bath.
07 - Bake for 40 to 45 minutes, or until the pudding is set around the edges but still retains a slight wobble in the center when gently shaken.
08 - Remove from the oven and carefully lift the baking dish from the water bath. Let cool for 15 minutes before serving warm or at room temperature. Top with whipped cream and a dusting of cinnamon if desired.
