- Preheat oven to 350F (325 convection bake). Line 1-2 large baking sheet(s) with parchment paper. Set aside.  
- In a large bowl, use an electric mixer to cream softened butter and sugar for ~5 minutes. Mixture will be light in colour and fluffy. Scrape down sides of bowl and mix one final time.  
- Add eggs, one by one, and vanilla extract. Mix each egg with butter mixture until it is well combined before proceeding.  
- In a medium bowl, combine flour, cream of tartar, baking soda, salt, and spices (cinnamon, all-spice, nutmeg, ginger, cloves). Whisk mixture together to sift and aerate.  
- Slowly, add flour mixture to wet (butter/sugar/egg) mixture. Scrape down sides of the bowl and mix one final time.  
- In a small, shallow bowl, combine sugar and spices (cinnamon +/- nutmeg) for sugar rolling.  
- Create small dough balls approximately 1 tbsp in size and drop into sugar mixture. Roll dough balls in sugar until completely coated, round, and smooth. Coat in sugar for a second time.  
- Place dough balls on baking sheet spaced ~2" apart.  
- Bake cookies for ~11 minutes or until cookies have spread and are slightly firm at the edges. Remove from oven and allow to cool on the baking sheet. Cookies will crack as they cool.  
- Enjoy!
