Slightly melt your vegan butter, and let it cool
Measure out canned pumpkin into a paper towel, wrap the paper towel around the pumpkin, and give it a squeeze, then set aside
Whisk the melted butter, brown sugar, and granulated sugar together in a medium bowl until no lumps remain in the sugar.
Whisk in the vanilla extract and blotted pumpkin until smooth
In a separate large bowl, whisk together the flour, salt, baking powder, baking soda, cinnamon, and pumpkin pie spice together.
Pour the wet ingredients into the dry ingredients and mix a large spoon or rubber spatula.
The dough should be soft. If added white chocolate, fold in the chips. It will take time to mix them in.
Cover the dough with plastic wrap and let chill for 30 minutes.
Remove the dough from the fridge and pre-heat the oven to 350 degrees
Combined the sugar and cinnamon in a bowl for the snickerdoodle coating
Scoop about 1.5 tablespoons of the dough and roll into a ball. Once formed, roll the dough in the sugar mixture.
Place the dough ball on a cookie sheet and flatten it slightly with the back of a spoon or measuring cup. Repeat until you have 12 dough balls on the sheet.
Cooke for 13-15 minutes or until the cookies are slightly brown on the edges and on top.
Once slightly brown on the edges, remove from the oven and let the cookies sit on the sheet for a few minutes.
Then move to the cooling rack to completely cooled.
Once cooled, enjoy. Place in an air-tight container for up to a week.
