Preheat your oven to 350°F and line or spray your muffin tin. In a large mixing bowl, use a hand mixer to cream together pumpkin puree, butter, and sugars until well combined. 15 ounces pure pumpkin puree, canned, ½ cup unsalted butter, softened, ½ cup granulated sugar, ½ cup light brown sugar
Add the eggs and vanilla extract and mix until just integrated.
1 teaspoon vanilla extract, 2 large eggs
Add flour, baking soda, salt, and pumpkin pie spice, and mix until the batter is smooth and there are no lumps.
2 cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon salt, 1 teaspoon pumpkin pie spice
Add milk, about 1/4 cup at a time, mixing in between, until well combined.
¾ cup milk
Fill each cup in your muffin tin about 3/4 of the way with the batter, leaving just a little bit of room to rise.
Bake 17-22 minutes until a toothpick comes out clean.
