Preheat oven to 350°F (175°C). Grease a baking pan.
Mix pumpkin puree and sugar in a large bowl until well combined.
Add eggs one at a time, mixing well after each addition.
Stir in milk and vegetable oil. In a separate bowl, whisk together flour, cinnamon, nutmeg, and ginger. Gradually add dry ingredients to wet ingredients, mixing until just combined.
Pour batter into prepared pan and bake for 30 minutes or until a toothpick inserted comes out clean.
Let cool before serving. Optional: garnish with whipped cream or cinnamon.
