Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper.
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Gently fold in the chocolate chips and fresh blueberries, distributing them evenly.
Use a cookie scoop or spoon to drop rounded tablespoons of dough onto the prepared baking sheets, leaving space between cookies.
Bake for 10-12 minutes, or until the edges are lightly golden brown and the centers are just set.
Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
