Preheat your oven to 350°F (175°C) and line an 8x8-inch baking dish with parchment paper, leaving an overhang on the sides for easy removal.
In a large mixing bowl, combine the melted butter and peanut butter. Whisk until smooth and well combined.
Add the granulated sugar, brown sugar, egg, and vanilla extract to the bowl. Mix thoroughly until the mixture is smooth and creamy.
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
Fold in the semi-sweet chocolate chips evenly throughout the dough.
Spread the batter evenly into the prepared baking dish, smoothing the top with a spatula.
Bake in the preheated oven for 18-22 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs.
Remove from the oven and allow the cookie bars to cool completely in the pan.
Once cooled, use the parchment paper overhang to lift the bars out of the pan. Cut into 12 equal-sized squares and serve.
