Preheat your oven to 350°F (175°C) to ensure even baking and perfectly chewy cookies.
In a large mixing bowl, combine the softened butter, brown sugar, and white sugar. Use an electric mixer to beat them together until light and fluffy, about 2-3 minutes.
Add the eggs and vanilla extract to the creamed mixture. Mix until well combined and smooth.
In another bowl, whisk together the all-purpose flour, instant chocolate pudding mix, baking soda, and salt to evenly distribute dry ingredients.
Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Avoid overmixing.
Gently fold in the semisweet chocolate chips using a spatula, ensuring even distribution throughout the dough.
Drop rounded tablespoons of dough onto a baking sheet lined with parchment paper, spacing them apart. Bake for 10-12 minutes until edges are set but centers remain soft.
Allow cookies to cool on the baking sheet for about 5 minutes before transferring to a wire rack to cool completely. Enjoy warm or at room temperature!
