Step 1: Prepare the Pan and Preheat the Oven

• Preheat your oven to 350°F (175°C).
• Grease and line a 9×13-inch (23×33 cm) baking pan with parchment paper, leaving some overhang for easy removal.

Step 2: Mix the Wet Ingredients

• In a large mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth.
• Add the eggs one at a time, whisking well after each addition.
• Stir in the vanilla extract.

Step 3: Combine the Dry Ingredients

• In a separate bowl, mix the flour, baking powder, and salt.
• Gradually fold the dry ingredients into the wet mixture until just combined. Avoid overmixing.

Step 4: Add the Mix-ins

• Gently fold in the Dairy Milk chocolate chunks and caramel chips, ensuring they’re evenly distributed.

Step 5: Layer and Swirl

• Spread half of the blondie batter evenly into the prepared pan.
• Drizzle half of the caramel sauce over the batter and gently swirl with a knife or skewer.
• Add the remaining blondie batter on top, spreading it evenly. Drizzle the remaining caramel sauce and swirl again.

Step 6: Bake

• Bake for 30-35 minutes, or until the edges are set and golden, and the center is still slightly soft.
• A toothpick inserted into the center should come out with a few moist crumbs for a fudgy texture.

Step 7: Cool and Slice

• Allow the blondies to cool completely in the pan.
• Once cooled, use the parchment overhang to lift them out. Slice into squares and enjoy!
