Ingredients
Scale
1 cup (2 sticks) unsalted butter, melted
1 cup brown sugar, packed
½ cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
2 ½ cups all-purpose flour
1 teaspoon baking soda
½ teaspoon baking powder
½ teaspoon salt
1 ½ cups chocolate chips (or mix-ins like nuts or M&Ms)
Instructions
Preheat oven to 350°F (175°C) and grease or line a 9×13-inch baking sheet with parchment paper.
In a large bowl, whisk together melted butter, brown sugar, and granulated sugar until smooth.
Add eggs and vanilla, mixing until combined.
In a separate bowl, whisk together flour, baking soda, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients, stirring until just combined.
Fold in chocolate chips (or other mix-ins).
Spread the cookie dough evenly into the prepared sheet pan.
Bake for 18-22 minutes, or until golden brown around the edges and slightly soft in the center.
Let cool before cutting into squares or bars.
Notes
For a gooier texture, bake on the lower end of the time range.
Customize with mix-ins like white chocolate chips, peanut butter chips, or chopped nuts.
Store leftovers in an airtight container at room temperature for up to 4 days.
