01 - Preheat the oven to 350°F. Line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a medium bowl, whisk together the all-purpose flour, baking soda, and sea salt until thoroughly blended.
03 - In a large bowl, beat the softened butter, brown sugar, and granulated sugar together with an electric mixer or whisk until the mixture is light and fluffy, about 2 minutes.
04 - Add the eggs one at a time, beating well after each addition. Mix in the pure vanilla extract until the mixture is smooth.
05 - Gradually add the dry ingredients to the wet ingredients, mixing with a spatula or mixer on low speed until just incorporated. Avoid overmixing.
06 - Fold in the semi-sweet chocolate chips, chopped dried tart cherries, and nuts if using. Ensure even distribution throughout the dough.
07 - Spread the dough evenly into the prepared baking pan and smooth the surface with a spatula.
08 - Bake for 22 to 25 minutes, or until the edges are golden brown and the center is just set.
09 - Cool completely in the pan on a wire rack. Use the parchment paper overhang to lift out, then cut into 16 bars.
