Ingredients
Method
- Preheat oven to 350°F (175°C) and line baking sheet with parchment paper.
- Cream butter, granulated sugar, and brown sugar until light and fluffy.
- Mix in egg and vanilla until just combined.
- In a separate bowl, whisk flour, baking soda, salt, and cornstarch.
- Gradually mix dry ingredients into wet ingredients until dough forms.
- Gently fold in white chocolate chunks.
- Carefully fold in frozen blueberries without overmixing.
- Chill dough for 30–60 minutes.
- Scoop dough onto baking sheet and bake for 12–14 minutes until edges are set.
- Cool on tray for 5 minutes before transferring to rack.
Notes
Chilling the dough is essential to prevent spreading. Use frozen blueberries to reduce bleeding into the dough. Don’t overbake—cookies should look slightly soft in the center when removed.
