Tips for Perfect Marshmallow Brownies

Don’t overbake the brownies—you want them soft and fudgy.
Use mini marshmallows for even melting and a uniform topping.
For a more toasted look, broil the top for 1 minute, watching closely.
Add mix-ins like crushed graham crackers for a s’mores twist.

Serve these Marshmallow Brownies slightly warm for maximum gooeyness, or refrigerate them for a firmer texture. They pair wonderfully with vanilla ice cream, hot chocolate, or a cold glass of milk. These brownies also make great treats for birthday parties, bake sales, or holiday celebrations.
