Preheat your oven to 350°F (175°C): This step ensures that your cookies bake evenly.
Combine dry ingredients: In a medium bowl, whisk together 2 cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt. Set aside.
Mix wet ingredients: In a large bowl, cream ¾ cup unsalted butter with ½ cup granulated sugar and 1 cup packed light brown sugar until smooth and fluffy.
Add eggs and vanilla: Beat in 2 large eggs one at a time, followed by 2 teaspoons vanilla extract, mixing until fully incorporated.
Combine wet and dry ingredients: Gradually add the flour mixture to the wet ingredients until just combined.
Fold in blueberries: Carefully fold in 1 ½ cups fresh blueberries, ensuring they are evenly distributed without breaking them.
Drop cookie dough: Using a tablespoon or cookie scoop, drop rounded balls of dough onto a parchment-lined baking sheet, leaving some space between each cookie.
Bake: Place the baking sheet in the preheated oven and bake for about 10-12 minutes, or until the edges are lightly golden and the centers are set.
Cool the cookies: Remove the cookies from the oven and allow them to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
