Preheat your oven to 350 F (176°C) and adjust a rack to the middle.
In a large bowl or stand mixer, cream together ½ cup butter, ½ cup brown sugar, ½ cup powdered sugar until light and fluffy. Add ½ cup canola oil, 1 egg, and ½ tsp vanilla. Mix to incorporate. It's ok if a little chunky at this stage.
Add in 2¼ cups flour ~½ cup at a time, and mix until thoroughly combined.
Add the remaining ingredients: ½ tsp baking soda, ½ tsp cream of tartar, ¼ tsp salt, tea from 1 black tea bag (cut and emptied into the bowl), ½ cinnamon, ¼ tsp nutmeg, ¼ tsp ginger, ⅛ tsp cardamom, ⅛ tsp allspice. Mix on low until incorporated.
Make the cinnamon sugar by adding ¼ cup each of white sugar and cinnamon and mixing until combined.
Using a cookie scoop or two spoons, drop balls of dough into the cinnamon sugar and roll to coat. For large cookies, make ~17 balls, otherwise makes ~30 heaping Tbsp cookies
Place the dough balls onto a cookie sheet lined with parchment. Bake in the oven for 10-12 minutes for large cookies, 8-10 for regular sized. Let cool.
