Ingredients

- ½ teaspoon baking soda
- ¼ teaspoon salt
- 1 cup all-purpose flour
- 1 cup semi-sweet chocolate chips
Directions
Preheat Your Oven
Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
Mix the Wet Ingredients
In a large bowl, combine the melted butter, peanut butter, brown sugar, and granulated sugar. Beat until smooth and creamy. Add the eggs and vanilla extract, mixing well after each addition.
Incorporate the Dry Ingredients
In another bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the Chocolate Chips
Gently fold in the chocolate chips, ensuring they are evenly distributed throughout the batter.
Bake to Perfection
Pour the batter into the prepared baking dish and spread it evenly. Bake for 25-30 minutes or until the edges are golden brown and a toothpick inserted in the center comes out clean. Let the bars cool completely before cutting into squares.

Variations
- Add ½ cup of chopped nuts like walnuts or pecans for extra crunch.
