Add the vanilla ice cream, pumpkin puree, ½ cup milk, and 1 teaspoon pumpkin pie spice to a blender.
Blend until smooth and creamy.
Add more milk, a little at a time, if you prefer a thinner milkshake.
Taste and add additional pumpkin pie spice or maple syrup/brown sugar if desired.
Pour into glasses and top with whipped cream.
Sprinkle with a little pumpkin pie spice before serving.
Recipe Notes
Start with less milk and add more until you reach your preferred consistency.
Adjust the pumpkin pie spice to taste for a stronger or milder fall flavor.
Maple syrup or brown sugar is completely optional if you prefer a less-sweet milkshake.
