Preheat oven to 350*F . Line a baking sheet with parchment.
In a small bowl combine the sugar and cinnamon to roll the cookies. Set aside.
3 Tbsp Granulated Sugar, ¾ tsp Cinnamon
In a large bowl using a hand mixer, or in the bowl of a stand mixer fitted with the paddle attachment, cream the vegan butter and brown sugar until well combined and fluffy.
8 Tbsp Vegan Butter, 1 Cup Light Brown Sugar, tightly packed
Add the pumpkin purée, non-dairy milk and vanilla and mix on low until well combined.
⅓ Cup Pumpkin Purée , 2 tsp Vanilla Extract, 1 Tbsp Non-Dairy Milk
Then, add the flour, pumpkin pie spice, baking powder, baking soda and salt and mix until just combined.
1 ½ Cups All-Purpose Flour, 2 ½ tsp Pumpkin Pie Spice, ½ tsp Baking Powder, ½ tsp Baking Soda, ¼ tsp Kosher Salt
Using a 3-tablespoon cookie scoop, scoop 8 dough balls onto a parchment- lined baking sheet. Roll each dough ball in cinnamon sugar and place back onto the baking sheet.
Bake in a 350*F oven for 13-15 minutes. The edge of the cookies should feel set when pressed with a finger. Allow the cookies to cool on the baking sheet for 10 minutes, then transfer to a cooling rack to finish cooling.
Repeat with the remaining cookie dough.
