Preheat your oven to 350 degrees. Line baking sheet(s) with parchment paper or silicone, or spray with cooking spray.
In a large bowl, beat the butter, brown sugar, and white sugar for 2-3 minutes at medium speed with an electric mixer. Beat in the egg and vanilla.
Whisk together the flour, cinnamon, soda, baking powder, and salt in a small bowl. Add to the wet ingredients and stir until flour mixture is incorporated.
Use a cookie scoop to portion the dough into tablespoon-sized balls.
Combine the sugar and cinnamon in a small bowl. Roll the cookie dough balls in the cinnamon sugar mixture. Place on prepared cookie sheet at least 2 inches apart.
Bake in preheated oven at 350° for about 10 minutes, or until barely set in the middle.
Let cookies cool on the pan for 3-4 minutes, then transfer to a wire rack to cool completely.
