# How To Make It:
01 - Preheat the oven to 350°F. Line two 8-inch square baking pans with parchment paper, allowing an overhang for easy removal.
02 - In a medium bowl, whisk melted butter and sugar until smooth. Add eggs and vanilla extract, mixing well. Sift in flour, cocoa powder, and salt, then stir just until combined. Fold in dark chocolate chips.
03 - In a separate bowl, whisk melted butter and brown sugar until creamy. Mix in egg and vanilla extract until blended. Fold in flour and salt just until incorporated. Stir in white chocolate chips and pecans, if using.
04 - Divide each batter evenly into the prepared pans and smooth the tops with a spatula.
05 - Bake both pans for 30 to 35 minutes, or until a toothpick inserted in the center emerges with a few moist crumbs.
06 - Allow the baked layers to cool completely in the pans on a wire rack. Using the parchment overhang, lift the baked slabs out and cut each into 12 squares.
07 - Arrange brownie and blondie squares together on a serving platter and present.
