1cup(227g)salted butter, softened to cool room temperature
1 ⅓cups(283g)granulated sugar
1large egg
2teaspoonspure vanilla extract
2 ½cups(355g)all-purpose flour (see note!)
½teaspoonbaking powder
½teaspoonbaking soda
½teaspoonsalt
Additional granulated sugar or sprinkles, for rolling
Instructions
Preheat the oven to 350 degrees F (see note). Line two large, rimmed baking sheets with parchment paper and lightly grease with cooking spray.
In the bowl of an electric stand mixer fitted with the paddle attachment or in a large bowl with a handheld electric mixer, cream together the butter and granulated sugar until lightly and fluffy, 3-4 minutes. Scrape down the sides of the bowl as needed.
Add the egg and vanilla and mix again for 1-2 minutes until the batter lightens in color. Scrape the sides of the bowl as needed.
In another bowl, whisk together the flour, baking powder, baking soda and salt.
Add the dry ingredients to the wet ingredients and mix until combined.
Scoop the cookie dough into rounded balls (about 2 tablespoons in size; I use my #40 cookie scoop), roll in granulated sugar or sprinkles and place on the prepared baking sheets a couple inches apart (about 12 cookies per baking sheet).
Bake for 11-13 minutes until slightly crackly on top (but not much color around the edges or bottom to keep them soft and chewy).
Let the cookies cool for a few minutes on the baking sheet before removing to a cooling rack to cool completely.
Notes
Flour: for a slightly thicker/puffier cookie, add 2-4 extra tablespoons flour. Cookies Spreading: if the cookies spread and flatten too much while baking, try adding more flour per the note above or increase the baking temperature to 375 degrees F or use convection bake (if you have that function on your oven - see my Instagram experiment here to come to this conclusion).
