1-Preheat the oven: Preheat the oven to 350°F and grease a 12-inch cast iron skillet, then set it aside for later.

2-Melt the butter: Melt the butter in a large saucepan over medium heat, add the sugar, and stir until it’s smooth and shiny.

3-Mix dry ingredients: Remove from heat and mix in the cocoa, baking powder, salt, and vanilla extract until well combined.

4-Whisk eggs: Whisk in the eggs until the batter is smooth and glossy.

5-Stir in flour and chocolate chips: Stir in the flour and chocolate chips just until everything comes together without overmixing.

6-Prepare for baking: Pour the batter into the prepared skillet, drizzle the salted caramel sauce over it, and swirl gently with a knife for that marbled effect.

7-Bake: Bake for 30-35 minutes, checking with a toothpick that comes out with moist crumbs for that slightly gooey center.

8-Cool and serve: Let the brownies cool completely before slicing and serving; top with extra caramel sauce and ice cream if you like. If you don’t have a skillet, a 9×13 baking pan works just as well.
