A Spooky-Sweet Halloween Treat Everyone Will Love

Looking for a Halloween dessert that’s adorable, chocolatey, and ridiculously easy? Meet Marshmallow Ghost Brownies. They start with a pan of rich, fudgy brownies, and then each square gets topped with a little marshmallow “ghost” that you toast under the broiler until golden. Two mini chocolate chips become the eyes, and suddenly you’ve got the cutest — and gooeyest — Halloween treat on the table.

What makes this recipe a seasonal winner is the money moment: serve these warm and pull one square away from the pan. The toasted marshmallow stretches, the warm chocolate follows, and it’s pure fall-baking magic. Kids go wild for the ghosts; adults can’t resist the fudgy base. And because it starts with a boxed brownie mix, the whole thing comes together in about 45 minutes — perfect for a school party, a trunk-or-treat table, or a cozy Halloween movie night.

Why You’ll Love These

  • Foolproof: boxed brownie mix does the heavy lifting — no complicated baking required.
  • Spooky-cute: the toasted marshmallow ghosts are as fun to make as they are to eat.
  • Serve-warm gooey pull: broil, top, and serve for that stretchy, melty moment.
  • Kid-friendly: little hands can press in the chocolate-chip eyes.

Ingredients

  • 1 box (18.3 oz) fudge brownie mix
  • 2 large eggs
  • 1/2 cup vegetable oil
  • 1/4 cup water
  • 12 large marshmallows
  • 24 mini chocolate chips (for the ghost eyes)
  • 1 tbsp black gel icing (optional, for ghost mouths)

Step-by-Step Instructions

Gooey marshmallow pull from a ghost brownie

Step 1 — Prep the Pan

Heat your oven to 350°F. Line an 8×8-inch baking pan with parchment paper, leaving a little overhang so you can lift the brownies out later.

Step 2 — Mix and Bake

In a large bowl, whisk the brownie mix, eggs, vegetable oil, and water until the batter is smooth and glossy. Spread it evenly into the prepared pan and bake for 28–30 minutes, until the edges are set but the center still looks just slightly fudgy. Let cool in the pan for 20 minutes, then lift out and cut into 12 squares.

Step 3 — Add the Marshmallow Ghosts

Set your oven to broil. Stand one large marshmallow upright on each brownie square. Slide the pan under the broiler for 30–60 seconds, watching closely — marshmallows go from golden to burnt in seconds — until the ghosts are lightly toasted.

Step 4 — Give Them Eyes

While the marshmallows are still soft, press two mini chocolate chips into each one for eyes. If you’d like, dot on a tiny mouth with black gel icing. Let the ghosts set for about 5 minutes.

Step 5 — Serve Warm

Serve these while they’re still warm for the best gooey pull — the toasted marshmallow stretches, the chocolate follows, and the crowd goes wild.

Tips for Perfect Ghosts

  • Watch the broiler like a hawk. Thirty seconds can be the difference between golden and charred. Don’t walk away.
  • Stand the marshmallows upright so they hold their ghostly shape as they toast.
  • Add the eyes quickly while the marshmallow is still soft and tacky so the chips stick.
  • Use mini chocolate chips, not regular ones — they’re the right scale for the ghost faces.
  • Warm is best. If the brownies have cooled completely, give the squares a 10-second microwave warm-up before serving to revive the gooey pull.

Storage

Store leftover ghost brownies in an airtight container at room temperature for up to 3 days. The marshmallows will firm up as they sit, but the brownies stay fudgy. Warm individual squares in the microwave for 10 seconds before serving to bring back the gooey texture. Freezing is not recommended — the marshmallow ghosts don’t thaw well.

FAQs

Can I use a homemade brownie recipe instead of a mix?

Absolutely. Use your favorite 8×8-inch fudge brownie recipe — just bake it slightly underdone so the centers stay fudgy.

Can I make these ahead of time?

Yes — bake and decorate the brownies up to a day ahead. Keep them covered at room temperature and warm briefly before serving.

Do I need a broiler to toast the marshmallows?

The broiler is the easiest, but a kitchen torch also works beautifully and gives you precise control.

Are these good for a school Halloween party?

They’re a hit with kids — just check for allergies, since most brownie mixes contain or may contain wheat, egg, and soy.
