Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking pan and set it aside.
Melt the Butter: In a medium saucepan, melt the butter over low heat. Once melted, remove from heat and stir in the sugar, mixing until smooth.
Add Eggs and Vanilla: Add in the eggs, one at a time, mixing well after each addition. Stir in vanilla extract until thoroughly combined.
Combine Dry Ingredients: In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in Chocolate Chips: Gently fold in the chocolate chips to the brownie batter, ensuring they are evenly distributed.
Layer with Caramel Sauce: Pour half of the brownie batter into the greased pan. Drizzle half of the caramel sauce over the batter, then add the remaining brownie batter on top. Swirl the remaining caramel sauce over the top.
Bake: Place the pan in the oven and bake for about 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Cool and Serve: Allow the brownies to cool in the pan before cutting them into squares. Serve warm or at room temperature, and enjoy the deliciousness!
