3. Marshmallow Frosting

Tips & Troubleshooting
- Too dry brownies? Bake a few minutes less—moist crumbs on the toothpick are perfect.

- No kitchen torch? Pop under your oven’s broiler for 1-2 minutes, watching closely.

Creative Variations & Serving Ideas

- Nutty crunch: Sprinkle chopped pecans or almonds over the marshmallow topping before toasting.
