Substituting puff pastry for refrigerated crescent rolls alters the structural integrity of the base significantly, yielding a flakier and less pliable crust. Understanding how layers interact during baking prevents structural collapse upon cooling. Visual cues dictate doneness here because thermometers cannot measure the state of layered dough.
Preheating the oven to 375 degrees ensures the butter and dough layers react immediately upon entry. Watch the top crust closely at the 13-minute mark. Deep golden-brown coloring across the surface indicates that the laminated dough has cooked through and the butter has fully rendered. Pale spots signal underbaked dough that will taste gummy. Molten chocolate chips and puffed mini marshmallows beneath the top dough layer create trapped steam, meaning the visual appearance of the crust remains the primary indicator.
