Line a baking sheet with parchment paper and preheat oven to 375 degrees.
In a medium sized bowl, whisk dry ingredients together and set aside.
In a stand-up mixer using the paddle attachment (you can also use hand held electric mixer), beat sugar and butter on medium speed for 2 minutes or until white and fluffy. Add in egg and vanilla and mix for another 2-3 minutes until everything is combined.
Add in flour and mix together on low speed until dry ingredients are fully incorporated into wet. Using a cookie scooper (equal to 1-2 tablespoons) scoop out dough and then roll in your hands to form a ball. Place on baking sheet and using your hands lightly press down to flatten out cookie a little bit.
Bake in oven for 8-10 minutes or the bottoms are golden. Let cool on baking sheet for 5 minutes before transferring to cooling rack to cool completely.
Combine all ingredients well with a mixer.
