Preheat your oven to 350°F (175°C) while you line a baking sheet with parchment paper.

In a large mixing bowl, beat together 1 cup of granulated sugar and 1 cup of softened butter until light and fluffy, about 2-3 minutes.

Add 1 egg, 1 ½ teaspoons of vanilla extract, ½ teaspoon of salt, and ½ teaspoon of baking soda. Mix until combined and smooth.

Gradually add 3 cups of all-purpose flour, mixing on low speed until a soft dough forms.

If dough seems too dry, add up to 2 tablespoons of milk and mix just until incorporated.

Gently mix in 1 cup of white chocolate morsels and then fold in 1 cup of fresh blueberries carefully.

Drop rounded tablespoonfuls of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake for 10-12 minutes or until the edges are golden brown and the centers are set.

Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a cooling rack.
