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