Preheat your oven to 375°F (190°C) and line baking sheets with parchment paper. Whisk together flour, baking soda, and salt in a medium bowl. Set aside.

In a large mixing bowl, cream together the butter and peanut butter with granulated and light brown sugars until fluffy. Incorporate the egg and vanilla, then add the dry mixture and fold in the chocolate chips.

Scoop the dough onto prepared sheets with space between each. Bake for 8-10 minutes until edges are golden; let cool for 5 minutes before transferring to a rack.
