Start by measuring all the dry spices into a small bowl. Whisk together the turmeric, cinnamon, nutmeg, and black pepper until they are well combined. Add the freshly grated ginger at this point to ensure even distribution.
Combine the pumpkin puree, milk, brewed espresso or coffee, honey or maple syrup, and vanilla extract in a blender or saucepan, then add the prepared spice mix. Heat the mixture gently while stirring until warm and fully blended.
Pour the latte mixture into two mugs, allowing the foam to rise to the top. Finish each mug with a generous swirl of whipped cream and a light dusting of pumpkin spice or cinnamon. For an extra decorative touch, add a cinnamon stick if desired.
