Equipment

  • Mixing bowls (one large, one medium)
  • Whisk
  • Spatula or wooden spoon
  • Measuring cups and spoons
  • Baking sheet
  • Parchment paper or silicone baking mat
  • Wire cooling rack
  • Refrigerator (for chilling dough)
  • Oven

Ingredients
  

  • 2 ¼ cups 280g all-purpose flour (or bread flour for extra chewiness)
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ¾ cup 170g unsalted butter, melted
  • 1 cup 200g brown sugar, packed
  • ½ cup 100g granulated sugar
  • 1 large egg + 1 egg yolk
  • 2 teaspoons vanilla extract
  • 1 tablespoon cornstarch for extra softness
  • 1 tablespoon milk for moisture retention
  • 1 ½ cups 270g chocolate chips

Instructions
 

  • Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, salt, and cornstarch. Set aside.
  • Melt Butter & Mix Sugars: In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until well combined.
  • Add Eggs & Vanilla: Mix in the egg, egg yolk, and vanilla extract until smooth.
  • Incorporate Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Avoid overmixing.
  • Add Milk & Chocolate Chips: Stir in the milk and chocolate chips. The dough will be thick.
  • Chill the Dough: Cover the dough and refrigerate for at least 1 hour (or overnight for maximum chewiness).
  • Preheat Oven & Prep Baking Sheet: Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
  • Scoop & Shape Dough: Roll dough into 2-tablespoon-sized balls and place them 2 inches apart on the prepared baking sheet.
  • Bake the Cookies: Bake for 9-11 minutes, or until the edges are set but the centers still look slightly underbaked.
  • Cool & Enjoy: Let cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

Chilling the dough is crucial for enhanced flavor and a thick, chewy texture.
For extra chewiness, substitute ½ cup of the all-purpose flour with bread flour.
Slightly underbaking will keep the centers soft.
Store cookies with a slice of bread in an airtight container to maintain moisture.
