Ingredients:
- 1 cup (225g) unsalted butter
- 1 1/4 cups (250g) light brown sugar, packed
- 1/2 cup (100g) granulated white sugar
- 1 large egg, room temperature
- 1 large egg yolk, room temperature
- 1 tablespoon (15ml) vanilla bean paste or extract
- 2 1/4 cups (280g) all-purpose flour, spooned and leveled
- 1 teaspoon (5g) baking soda
- 3/4 teaspoon (4g) fine sea salt
- 1 1/2 cups (250g) semi-sweet chocolate chips or chunks
- 2 oz (60g) dark chocolate bar (70%), roughly chopped
- 1 pinch flaky sea salt, for finishing
Instructions:
- Start by melting the butter in a light-colored skillet over medium heat. Whisk constantly as it bubbles and pops. Once the popping subsides and you see mahogany-colored bits at the bottom and it smells intensely nutty, remove it from the heat immediately.
- Pour the browned butter into a large mixing bowl and let it cool for 10 minutes.
- Whisk the light brown sugar and granulated white sugar into the cooled butter until no lumps remain.
- Add the large egg, egg yolk, and vanilla. Whisk vigorously until the mixture lightens in color and becomes ribbony.
- Sift the dry ingredients. In a separate bowl, whisk the flour, baking soda, and fine sea salt.
- Fold the dry ingredients into the wet mixture using a spatula until only a few streaks of flour remain. Over mixing at this stage will lead to a tough, bread like cookie.
- Add the semi sweet chips and the chopped dark chocolate bar, folding gently until the chocolate is evenly distributed.
- Use a large scoop to form 18 balls of dough. If you have time, chill these for 30 minutes.
- Arrange on a lined sheet and bake at 175°C for 10 minutes until the edges are set and golden but the centers look slightly underdone.
- Immediately sprinkle with flaky sea salt and let them rest on the pan for 5 minutes. Carryover cooking finishes the centers while the edges crisp up.
