Preheat the oven to 350°F (175°C). Line a baking sheet or pizza pan with parchment paper for easy removal, if desired.
In a mixing bowl, whisk together the flour, baking soda, and salt. Set aside.
In another bowl, cream the softened butter, granulated sugar, and brown sugar together until light and fluffy.
Add in the vanilla extract and egg, mixing until well combined.
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Avoid overmixing.
Fold in the chocolate chips until evenly distributed throughout the dough.
Spread the dough onto the prepared baking sheet or pizza pan, shaping it into a round pizza shape about ½ inch thick.
Bake in the preheated oven for 15 minutes or until the edges are golden brown and the center is set.
Remove from the oven and allow it to cool for a few minutes. Dust with powdered sugar if desired before slicing into wedges.
