Begin by preheating your oven to 350°F (175°C). Prepare a 9x13 inch baking pan by greasing it with butter or cooking spray, and then line the bottom with parchment paper for simpler removal later.
In a large mixing bowl, take the melted butter and combine it with both the granulated sugar and packed brown sugar. Whisk these together vigorously until the mixture is smooth and well blended.
Introduce the eggs into the mixture one by one, ensuring to whisk vigorously after each egg to thoroughly incorporate it. Follow by stirring in the vanilla extract, mixing until just combined.
In a separate bowl, sift together the all-purpose flour, cocoa powder, baking powder, and salt to ensure an even distribution of the dry ingredients.
Gradually add the dry ingredient mixture into the wet ingredients, gently folding them together with a spatula. Take care not to overmix; you want to keep the batter light.
Carefully fold in the chopped pecans and semi-sweet chocolate chips, being sure they are evenly dispersed throughout the brownie batter.
Pour half of the chocolate brownie batter into your prepared baking pan. Use a spatula to spread it out evenly across the base of the pan.
Drizzle half of the caramel sauce over the layer of brownie batter, allowing it to pool in some areas for delicious pockets of caramel.
Spoon the remaining brownie batter over the caramel layer, smoothing it out gently. Drizzle the rest of the caramel sauce on top, and with a toothpick, lightly swirl the caramel into the brownie layer to create an attractive marbled design.
Place the tray in the oven and bake for 30-35 minutes. To check for doneness, insert a toothpick into the center of the brownies; it should come out with a few moist crumbs clinging to it.
After baking, remove the brownies from the oven and allow them to cool in the pan on a wire rack for at least 30 minutes. This will help them set up before cutting into squares.
Notes
Serve warm with vanilla ice cream and extra caramel sauce for a decadent treat.
