Description

This single levain chocolate chip cookie recipe delivers a rich, buttery, and chewy treat with a perfect balance of sweet brown sugar and crunchy walnuts. Ideal for one or two servings, this easy-to-make cookie uses a unique combination of cornstarch and all-purpose flour for that classic levain texture, baked to golden perfection.


Ingredients

Scale

Cookie Dough

  • 3 tbsp butter (salted or unsalted, softened)
  • 3 tbsp brown sugar
  • 1 tbsp granulated sugar
  • 1/4 tsp vanilla extract
  • 1 egg yolk
  • 1/2 cup all-purpose flour
  • 3 tbsp cornstarch
  • 1/8 tsp baking soda
  • 1/8 tsp salt
  • 2 tbsp chocolate chips
  • 2 tbsp walnuts

Instructions

  1. Preheat Oven: Preheat the oven to 350°F (175°C), then line a baking sheet with parchment paper and set aside.
  2. Cream Butter and Sugars: In a medium bowl, cream the softened butter, granulated sugar, and brown sugar together until smooth and creamy to create a consistent base for the dough.
  3. Add Vanilla and Egg Yolk: Mix in the vanilla extract and egg yolk thoroughly, ensuring everything is well combined for flavor and structure.
  4. Incorporate Dry Ingredients: Add the flour, baking soda, cornstarch, and salt to the wet mixture, stirring until the flour mixture disappears and the dough begins to form.
  5. Add Mix-ins: Fold in the chocolate chips and walnuts evenly throughout the dough for texture and bursts of flavor.
  6. Shape and Bake: Roll the cookie dough into a ball and place it on the prepared baking sheet. Optionally, top with extra chocolate chips. Bake in the preheated oven for 14 minutes until the edges are set and the cookie is golden.
  7. Cool: Let the cookie cool on the baking sheet for 10-15 minutes to firm up before enjoying.

Notes

  • If you prefer a chewier texture, slightly underbake the cookie by 1-2 minutes.
  • For a nuttier flavor, toast the walnuts lightly before folding them into the dough.
  • You can substitute walnuts with pecans or skip nuts entirely for a nut-free version.
  • Chilling the dough for 30 minutes before baking can help prevent spreading.
  • Use parchment paper or a silicone baking mat for easy cleanup and to prevent sticking.
