Ingredients:

• 2 ½ cups all-purpose flour
• 2 teaspoons baking powder
• 1 teaspoon baking soda
• ½ teaspoon salt
• 1 cup unsalted butter
• 1 cup packed brown sugar
• ½ cup granulated sugar
• 1 large egg
• 2 large egg yolks
• 3 teaspoons vanilla extract
• 10 ounces chocolate chips (milk or semi-sweet, your choice)
• Flaked sea salt, for topping

Instructions:

1. Preheat your oven to 350°F (175°C).  
2. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.  
3. Heat a 12-inch oven-safe skillet (preferably cast iron) over low heat for about 5 minutes. Add the butter and let it melt completely. Once melted, stir in both sugars with a wooden spoon. Turn off the heat under the skillet, or remove it from the burner entirely.  
4. In a separate bowl, whisk together the egg and egg yolks. Add the egg mixture to the skillet and stir quickly to combine, being careful not to cook the eggs with the residual heat. Stir in the vanilla extract.  
5. Gradually fold in the dry ingredients, mixing until just combined. The dough will be thick, but should come together after a minute or two. If desired, use a damp paper towel to wipe away any excess flour on the sides or edges of the skillet.  
6. Stir in the chocolate chips, ensuring they are evenly distributed throughout the dough.  
7. Bake in the preheated oven for 20-25 minutes, or until the cookie is mostly set in the center with a slight wobble.  
8. Remove from the oven and sprinkle with flaked sea salt.  
9. Serve warm with a scoop of vanilla ice cream for an extra indulgent treat.
