  • ¾ cup Dutch-processed cocoa powder

  • ½ cup packed brown sugar
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • ½ teaspoon kosher salt

For the Swiss Meringue Topping

  • 4 large egg whites
  • 1 cup granulated sugar
  • ½ teaspoon cream of tartar
  • 1 teaspoon vanilla extract

Optional Garnishes

Instructions for Easy S’mores Brownies from Scratch

Step 1: Make the Graham Cracker Crust

Preheat that oven to 350°F (175°C). Line a 9×9” metal pan with parchment, leaving an overhang—makes lifting easier.

Now crush your grahams. Pulse in a food processor or go old-school with a rolling pin and a Ziploc. You want fine, sandy crumbs. Mix with sugar and butter until it looks like wet sand. Pack it into your pan—firmly. Use the bottom of a measuring cup and press evenly.

Bake for 8–10 minutes. You’re not looking for color here, just a set crust. Cool while you make the brownie batter.

Chef tip: Chill the pan before baking so the butter sets slightly—helps keep the crust from puffing.

Step 2: Prepare and Bake the Brownie Layer

Melt the butter in a saucepan over low heat. Stir in the cocoa powder until it becomes a thick, glossy paste. Let it cool slightly—don’t scramble your eggs.

In a large bowl, whisk the sugars, eggs, and vanilla until pale and ribbony—this aeration gives your brownies that shiny top.

Now pour in your cocoa-butter mix. Stir to combine. Sift in flour and salt. Fold gently. You don’t want to build gluten here—just combine till smooth.

Pour batter over the cooled crust, smoothing with an offset spatula.

Bake 30–35 minutes, or until the edges are set and the center has the slightest jiggle. That’s key. Overbaking? That’s how you lose the fudge.

Frank note: “Most people mess this up—they bake until it’s fully set and end up with dry cake. Take it out while it still trembles a bit.”

Cool completely. No shortcuts here. The meringue needs a stable base.

Step 3: Make the Swiss Meringue

Set up a double boiler. Add egg whites, sugar, and cream of tartar to the bowl. Whisk constantly over simmering water until the sugar dissolves and the mix hits 160°F (about 5–7 minutes). Rub a little between your fingers—it should feel smooth.

Move the bowl to your stand mixer (or hand mixer) and beat until stiff, glossy peaks form—about 5–7 minutes. Add vanilla at the end.

Mini lesson: Swiss meringue is more stable than fluff or regular whipped whites. It holds its shape when torched—and doesn’t collapse like your uncle’s camping tent.

Step 4: Assemble and Torch

Spread that meringue on top of the cooled brownies. Use a spoon to swirl those peaks. You want drama. Peaks catch the flame and turn golden.

Now grab your torch. Toast the meringue until golden brown, with little dark tips—don’t rush. Keep the flame moving.

No torch? Use the broiler, top rack, door cracked open. Watch it like a hawk. It’ll brown in under 2 minutes.

While still warm, sprinkle chopped Hershey’s over the top. They’ll melt just enough to soften—pure nostalgia.

Let it sit 10 minutes before slicing. Wipe the knife clean between cuts. Use hot water if you want clean edges.

Tips & Notes for Perfect Marshmallow Brownies Every Time

  • Marshmallow swap: You can use marshmallow fluff—but Swiss meringue tastes less sweet and looks way better when toasted.
  • Graham cracker hack: No grahams? Try digestive biscuits or crushed Biscoff.
  • Torch tip: A culinary torch gives you control. Broiler’s okay, but risky.

Storage Instructions

Store in an airtight container at room temp for 2–3 days. The meringue will hold up if you used the Swiss method. If it softens, re‑torch before serving.

Avoid the fridge unless your kitchen’s blazing—cold dulls the crust texture.

Serving Suggestions for Rich Chocolate Desserts

  • Serve day-of for peak gooeyness.
  • Slice into small squares—this is a rich chocolate dessert.
  • Add a scoop of vanilla ice cream and a drizzle of melted chocolate for next-level indulgence.
  • Great for summer BBQs, potlucks, or when you just miss the taste of a campfire.
