Preheat oven to 350°F.
In a stand mixer, add sugar and vanilla, and egg replacer mixture or 2 eggs.
Add brown sugar, pumpkin and dairy free milk (all while the stand mixer is on slow/low).
Add the baking powder, xanthan gum, all the spices and salt.
Allow to beat for one minute and then add the GF All Purpose Flour.
Mix on medium speed for 2 minutes, scraping down the sides halfway through.
Add the chocolate chips and mix on slow until they are mixed through the batter evenly.
Line your muffin pan with liners and use an ice cream scooper to scoop the batter in.
Bake 25-30 minutes or until a toothpick comes out clean.
