Ingredients:
- 1 cup (2 sticks / 227g) unsalted butter, cut into cubes (for the Brown Butter)
- 2 ¼ cups (281g) all-purpose flour, plus more for dusting
- 1 teaspoon baking soda
- 1 teaspoon kosher salt
- ¾ cup (150g) packed light brown sugar
- ½ cup (100g) granulated sugar
- 1 large egg
- 1 large egg yolk
- 2 teaspoons vanilla extract
- 1 cup (170g) dark chocolate chips or chunks (60-70% cacao)
- ½ cup (100g) granulated sugar (for the Salted Caramel)
- ¼ cup (60ml) heavy cream
- 4 tablespoons (½ stick / 57g) unsalted butter, cut into cubes (for the Salted Caramel)
- ½ teaspoon kosher salt, plus more to taste (for the Salted Caramel)
Instructions:
- Melt butter in a saucepan over medium heat. Continue cooking, swirling occasionally, until it turns golden brown and smells nutty. Pour into a heatproof bowl and let cool completely. Chill in fridge until mostly solid.
- In a clean saucepan, heat sugar over medium heat, without stirring, until it melts and turns amber. Gradually whisk in heavy cream, being careful as it may bubble vigorously. Add butter and salt, and stir until smooth and glossy. Remove from heat and set aside to cool slightly.
- Whisk together flour, baking soda, and salt in a medium bowl.
- In a stand mixer or with a hand mixer, cream together the cooled brown butter, brown sugar, and granulated sugar until light and fluffy.
- Beat in the egg and egg yolk, one at a time, then stir in the vanilla extract.
- Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
- Fold in the dark chocolate chips or chunks.
- Press the cookie dough evenly into the prepared springform pan lined with parchment paper.
- Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until the edges are golden brown and the center is set but still slightly soft.
- Let the cookie cake cool completely in the pan before releasing it. Drizzle generously with the prepared salted caramel.
- Slice and serve, perhaps with a scoop of vanilla ice cream.
