Spread a thin layer of Biscoff spread over the crust if using.
Evenly layer chocolate bars or chocolate chips on top of the crust.
Sprinkle marshmallows or spread marshmallow creme evenly over the chocolate.
Return to the oven and bake for 10–12 minutes, or until the marshmallows are golden and chocolate is melted.
Let cool before slicing into bars.

Storage/Reheating
