Pioneer Woman S’mores Brownies

This fudgy gooey Pioneer Woman S’mores Brownies is made with graham crackers, brownie mix, and large marshmallows and ready in 55 minutes. Pulling the pan from the oven reveals a golden, puffed marshmallow topping that stretches beautifully when sliced. I find this recipe brings the campfire indoors without smelling like woodsmoke.

Why This Classic Works

I used to struggle with layered campfire desserts being too sweet or completely falling apart when sliced. Stacking the graham cracker crust beneath a dense brownie base provides the perfect sturdy foundation.

The real trick I discovered is using large marshmallows halved and placed sticky side down. They melt securely into the chocolate layer while getting perfectly toasted and puffed on top.

Pioneer Woman S’mores Brownies Ingredients

• 1 1/2 cups graham cracker crumbs
• 6 tablespoons unsalted butter, melted
• 1 box (18.3 ounces) fudge brownie mix
• 1/2 cup vegetable oil
• 1/4 cup water
• 2 large eggs
• 1 1/2 cups large marshmallows, halved
• 1/2 cup semi-sweet chocolate chips

How To Make Pioneer Woman S’mores Brownies

1. Prep the Crust: Preheat your oven to 350°F and line an 8×8-inch baking pan with parchment paper. Mix the graham cracker crumbs and melted butter, then press firmly into the bottom of the pan.
2. Bake the Base: Bake the graham cracker crust for 5 minutes to set it. Remove from the oven and let it cool slightly while you prepare the brownie batter.
3. Mix the Brownies: In a large bowl, whisk together the brownie mix, oil, water, and eggs until just combined. Pour the thick batter evenly over the baked crust.
4. Bake the Brownies: Place the pan back in the oven and bake for 35 minutes, or until a toothpick inserted in the center comes out mostly clean.
5. Add the Topping: Remove from the oven and immediately top with the halved marshmallows and chocolate chips. Return to the oven for 3 to 5 minutes until the marshmallows are puffed and golden brown.

Recipe Tips

• Line your pan: Parchment paper with an overhang lets you lift the entire block out for clean slicing.
• Wet your knife: A slightly damp, warm knife prevents the gooey marshmallow from sticking and tearing the brownies.
• Do not overbake: The chocolate layer should still be slightly fudgy when you add the toppings so it does not dry out.

What To Serve With S’mores Brownies

A tall glass of cold milk cuts through the rich, sweet marshmallow and chocolate layers perfectly. If you want a full dessert experience, serve a warm square alongside a scoop of vanilla bean ice cream.

How To Store

Keep these in an airtight container at room temperature for up to 3 days. I do not recommend freezing them, as the marshmallow topping becomes gummy when thawed.

FAQs

Can I make the brownie batter from scratch?

Yes, you can substitute your favorite homemade fudgy brownie recipe for the boxed mix. Just ensure it yields enough batter for an 8×8-inch pan.

Can I use marshmallow fluff instead?

Fluff works in a pinch but will not toast or hold its shape as well as real marshmallows. Halved large marshmallows yield the best visual and textural results.

Why did my marshmallows burn?

Marshmallows toast very quickly in the oven, usually under 5 minutes. Keep a close eye on them during the final baking stage to prevent charring.
