Preparation Steps

• Start by preheating your oven to 350°F (175°C). Prepare a baking dish by greasing it or lining it with parchment paper for easy removal later.
• In a large mixing bowl, combine the softened butter, brown sugar, and granulated sugar. Cream them together until the mixture is light and fluffy.
• Add in the eggs one at a time, mixing well after each addition, then blend in the vanilla extract.
• Gradually mix in the all-purpose flour until well incorporated. Finally, gently fold in the chocolate chips and nuts if you're using them.
• Spread the batter evenly in the prepared baking dish and smooth out the top with a spatula.
• Bake in the preheated oven for about 25 minutes or until the edges are golden and a toothpick inserted in the center comes out clean.
• Once out of the oven, let the bars cool in the pan for at least 10 minutes before transferring to a wire rack to cool completely. Cut into squares and enjoy!
