Preheat your oven to 350°F (175°C) and grease a muffin pan.

In a medium saucepan over low heat, combine whole milk, butter, and granulated sugar until fully dissolved.

In a large bowl, whisk pumpkin puree and eggs, then add the warm milk mixture.

Sift in flour, baking powder, pumpkin pie spice, and salt, folding gently until combined.

Pour batter into muffin pan, filling each cup halfway.

Bake for 30-35 minutes until set and golden.

Cool in the pan for 10 minutes, then transfer to a wire rack.
