Preparation Steps

• Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper. In a bowl, mix the flour, baking soda, and salt together until well combined.
• In another large bowl, cream together the softened butter, granulated sugar, and brown sugar until it's light and fluffy. This usually takes about 3-4 minutes using an electric mixer.
• Add the egg and vanilla extract to the butter mixture and beat until fully incorporated. Gradually add the dry ingredients, mixing just until the flour disappears.
• Gently fold in the blueberries, being careful not to crush them. Scoop the dough onto the prepared baking sheet, spacing them about 2 inches apart.
• Bake for 15-20 minutes or until the edges are golden brown. Let them cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
