Cream the Butter and Sugars:- Beat softened butter with both sugars until light and fluffy (2–3 minutes).
Add Eggs and Vanilla: Beat in eggs one at a time. Stir in vanilla extract.
Mix Dry Ingredients Separately: In a bowl, whisk together flour, baking soda, and salt. Gradually mix into the wet mixture until just combined.
Fold in the Chocolate: Stir in chocolate chips and chunks without overmixing.
Chill the Dough: Cover and refrigerate for at least 30 minutes, up to 48 hours.
Preheat and Shape: Preheat oven to 350°F (175°C). Scoop dough into 1.5-inch balls and place on a parchment-lined baking sheet.
Bake: Bake for 10–12 minutes until edges are golden. Centers may look slightly soft.
Cool: Let cookies cool on the tray for 5 minutes, then transfer to a wire rack.
