Preheat oven to 375.
In a medium bowl, cream the butter and xylitol. (I used a stand mixer, but you could easily do this by hand as well).
Add the eggs and vanilla; beat until just combined.
Mix in the baking blend, baking soda, baking powder, and all of the spices. Mixture will be crumbly and a bit dry.
Slowly pour in the 1/4 c + 2 tbsp brewed tea and mix well.
Form the cookies into balls - roughly two tbsp per cookie or a medium cookie scoop.
Roll each ball in the extra xylitol or low glycemic sweetener.
Place on a parchment covered cookie sheet and flatten with the bottom of a glass. The cookies will rise as they bake.
Bake for 10 minutes or until cookies have browned bottoms. They will be soft to the touch, even after sitting.
Store in the refrigerator for best results.
