Instructions
Preheat the oven to 350°F (175°C) and grease a 9×9-inch baking pan with nonstick spray.
In a medium bowl, mix together the melted butter, brown sugar, vanilla, and egg until well combined.
Stir in the flour, baking powder, salt, and baking soda until the batter comes together.
Fold in the chocolate chips, then pour the mixture into the prepared pan.
Bake for 20-25 minutes until golden brown. Let cool slightly, then dig in and enjoy every gooey bite!
