- 2 cups all-purpose flour – All-purpose flour serves as the foundation for these cookie bars, giving them stability without being too dense.

How to Make dessert for a crowd
1. Preheat the oven: Start by setting your oven to 350°F (175°C). While it warms up, grease and line a 9×13 inch baking pan with parchment paper for easy removal later.
2. Cream the mixture: In a mixing bowl, combine 1 cup of softened unsalted butter, 1 cup of packed brown sugar, and 1/2 cup of granulated sugar. Beat together until the mixture is light and fluffy, about 3-5 minutes.
3. Add eggs and vanilla: Crack in 2 large eggs one at a time, ensuring each is fully incorporated before adding the next. Then, stir in 2 teaspoons of vanilla extract for that beautiful aromatic touch.
4. Whisk the dry ingredients: In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and 1/2 teaspoon of salt. Gradually fold this dry mix into your wet ingredients until just combined; be careful not to overmix!
5. Fold in chocolate chips: Gently fold in 2 cups of semi-sweet chocolate chips until they are evenly distributed throughout the batter, making every bite deliciously chocolatey.
6. Spread the batter: Pour the cookie batter into your prepared baking pan, spreading it evenly so that it bakes uniformly.
7. Bake to perfection: Place your pan in the preheated oven and bake for 20-25 minutes. Look for golden edges and a toothpick inserted in the center coming out clean – that’s when you know it’s done!
8. Cool and cut: Once baked, allow your cookie bars to cool in the pan before cutting them into squares, so they hold their shape beautifully.
Optional: Sprinkle with sea salt before serving for an extra flavor boost!

Make Ahead Options

For optimal quality, store uncooked batter in the fridge for up to 3 days or freeze it for up to a month; just remember to thaw it overnight before baking. This approach ensures that your dessert for a crowd is both convenient and irresistibly tasty!
