Sift together dry ingredients: flour, cinnamon, ginger, nutmeg, cloves, salt, baking powder, and baking soda.
Preheat oven to 350°F. Line a muffin tin with parchment paper muffin cups OR baking spray. (Do not use regular paper muffin cups.)
In a separate bowl, whisk together pumpkin puree, brown sugar, eggs, vanilla, and evaporated milk.
Gently stir dry ingredients into wet ingredients.
Fill prepared muffin cups about half full.
Bake for 20 minutes. Cupcakes will puff up during baking, but will settle as they cool.
Cool completely and then chill for 1 hour in the refrigerator before topping with whipped cream.
