Will a standard glass baking dish work just as well as metal for pressing the crumb crust? Glass retains heat differently and cools slower, so stick to a standard 9x13-inch metal pan to ensure the butter and sugar base sets evenly without weeping fat along the edges. When melting the semisweet chips and the supplemental peanut butter together, utilize a double boiler over simmering water rather than direct heat; chocolate scorches easily above 120 degrees Fahrenheit, turning grainy and dull. Stir the topping continuously with a rubber spatula until the mixture achieves a glossy, uniform sheen before pouring it over the chilled base. Chill the assembled pan in the refrigerator for a minimum of one full hour to firm the fats sufficiently for clean slicing. For dietary adjustments, butter can be swapped for plant-based margarine at a strict one-to-one ratio without altering the structural integrity of the crust. Store finished squares in an airtight container in the refrigerator for up to five days.
