Expert Tips & Tricks
✅ Chill the Dough – Refrigerating for at least an hour helps prevent excessive spreading. ✅ Use a Cookie Scoop – Ensures uniform cookies that bake evenly. ✅ Bake at 325°F (163°C) – This allows the marshmallows to melt into swirls without burning. ✅ Line Your Baking Sheet – Use parchment paper or a silicone mat to keep marshmallows from sticking. ✅ Add Marshmallows Midway – This keeps them visible and gooey rather than disappearing into the dough. ✅ Cool on the Pan – Let cookies set for a few minutes before transferring to a wire rack.
