Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a large bowl, cream together the butter and sugar until smooth.
Beat in the eggs one at a time, then stir in the vanilla.
Combine the flour, baking soda, baking powder, and salt; gradually blend into the creamed mixture.
Roll dough into a large ball and place on the prepared baking sheet. Flatten slightly.
Bake for 15-20 minutes in the preheated oven, or until edges are golden. Let cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
