Tips & Variations
- For a crunchy twist, sprinkle chopped pecans over the marshmallows before baking.
- Replace mini marshmallows with a crumble topping made from brown sugar, butter, and flour for a nutty flavor.
- Add a pinch of ground ginger or cloves to the filling for extra warmth and spice.
- Use maple syrup instead of brown sugar for a different sweetness profile.
Storage
Store leftovers covered in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through to keep the marshmallows from becoming soggy. You can also cover with foil and reheat in the microwave, though the topping may soften.
