Slowly add the powdered sugar until combined then add the egg, baking powder, vanilla, and salt and mix. Add flour in slowly, mixing everything together until evenly combined. Scrape sides if needed, cover with plastic wrap and place in fridge for one hour. Preheat oven to 375 degrees.In small bowl mix the cinnamon and sugar and set aside.Take dough out of the fridge and roll 1 inch sie balls out. Roll the dough balls in your cinnamon and sugar mix.Cover a cookie sheet with parchment and place the sugared dough balls about 2 inches apart.Bake for 8-10 minutes, until just set. Make sure you do not overbake, it is hard to tell but they will puff up and you take your chances until you find your perfect minute. Let cookies cool for about 5 minutes after taking them out of the oven to let them finish and then your ready to dive in!
Notes
Make sure your oven is preheated all the way before placing the cookies in. Parchment paper helps the cookie to reduce spreading.Enjoy!
