Creating cutting cookie bars is a breeze when you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper.
2. Mix Wet Ingredients: In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until smooth. Beat in the eggs one at a time, then add the vanilla extract.
3. Combine Dry Ingredients: In another bowl, whisk together the flour, baking soda, and salt.
4. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined.
5. Add Mix-ins: Fold in the chocolate chips and nuts, if using. Ensure they are evenly distributed throughout the dough.
6. Spread Batter: Pour the batter into the prepared baking pan, spreading it evenly.
7. Bake: Bake for 25–30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean.
8. Cool: Remove from the oven and let the bars cool in the pan for about 15 minutes. Then, transfer them to a wire rack to cool completely.
9. Cut Bars: Once cooled, cut into squares or rectangles, depending on your preference.
