Directions :

Make sure to preheat your oven to 350º and line 2 baking sheets with parchment paper.
Then beat butter, granulated sugar, and brown sugar with an electric mixer, until light and creamy.

Next, add eggs, vanilla extract, and beat again for an additional 2 minutes. Immediately add flour, baking soda, salt, and mix until just combined
When finished, scoop balls, using a medium cookie scoop onto prepared baking sheets and add a pecan half to the top of each cookie. Bake until golden brown, about 10 to 15 minutes. Finally, cool cookies on a wire rack.
