Ingredients:

  • 1/2 cup (113g) unsalted butter, softened
  • 1/2 cup (100g) granulated sugar
  • 1/2 cup (100g) light brown sugar, packed
  • 1 large egg (50g), room temperature
  • 1 tsp (5ml) vanilla extract
  • 2 cups (250g) all-purpose flour
  • 1/2 tsp (3g) baking soda
  • 1/4 tsp (1.5g) salt
  • 1 cup (150g) fresh blueberries, rinsed and patted dry
  • 1 cup (170g) white chocolate chips
  • 1 tbsp (8g) cornstarch

Instructions:

  1. Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper or silicone mats.
  2. In a small bowl, toss the fresh blueberries with 1 tbsp (8g) of cornstarch until evenly coated to create a moisture barrier.
  3. In a large bowl, beat the softened butter, granulated sugar, and brown sugar together until the mixture is pale and fluffy.
  4. Beat in the egg and vanilla extract until the mixture is smooth and velvety.
  5. Whisk the flour, baking soda, and salt together, then slowly stir them into the wet ingredients using a spatula until just combined.
  6. Gently fold in the cornstarch-coated blueberries and white chocolate chips by hand to avoid over-mixing.
  7. Drop rounded tablespoons of dough onto the prepared baking sheets.
  8. Bake for 10-12 minutes, or until the edges are light golden brown but the centers still look slightly soft.
