Preheat the oven to 350 degrees. Line a couple baking sheets with parchment and set
aside.
In the bowl of a stand mixer fitted with the paddle attachment, combine the softened
butter and sugar. Cream until smooth and combined.
Add in the eggs and vanilla and mix well, scraping down the sides.
Add in the flour, cinnamon and baking powder. Mix well, scraping down the sides often
Meanwhile, in a small bowl, combine the sugar and cinnamon for the coating. Reserve
about 1 tablespoon worth to be sprinkled over the frosting later.
Using an ice cream scoop, scoop out the dough and roll in the cinnamon sugar mixture.
Place on the baking sheets, leaving about 2-3 inches between each cookie. Use the
bottom of a cup or similar to flatten each cookie into a disk about ½-¾ of an inch thick
Bake in the preheated oven for 10-12 minutes or until the center is set. Allow to cool
completely before decorating.
For the frosting - in the bowl of a stand mixer, combine the softened butter, cinnamon,
about half of the powdered sugar and milk. Mix on low until combined.
Add in the remaining powdered sugar and mix on low until combined. Bump up the
speed to medium and whip until smooth and fluffy. Add a dash more milk only if needed
to smooth it ou
Transfer the frosting to a piping bag. Set aside.
Once the cookies are cool, pipe a spiral of frosting over the top of each cookie.
Sprinkle a bit of the reserved cinnamon and sugar mixture.
