Why I Love This Recipe

This recipe is:

  • 🍫 Fudgy and rich from the brownie base
  • 🔥 Smoky and salty from crumbled bacon
  • 🍪 Crunchy and sweet from graham crackers and chocolate chips
  • ☁️ Topped with luscious marshmallow fluff for gooey, golden goodness

It’s a flavor bomb that combines salty, sweet, crunchy, gooey, and chewy all in one square.


📝 Ingredients

  • 1 box brownie mix (plus eggs, oil, and water as directed)
  • 4 strips of bacon, cooked and crumbled
  • 1 cup graham cracker crumbs
  • 1 cup chocolate chips
  • 1 cup marshmallow fluff

🔁 Ingredient Notes & Swaps

  • Brownie mix: Use your favorite brand—fudgy style preferred.
  • Bacon: Cook until crisp; thick-cut bacon adds extra texture.
  • Marshmallow fluff: You can also use mini marshmallows for a more toasted top.
  • Add-ins: Add chopped pecans or a sprinkle of sea salt for extra dimension.

👨‍🍳 Instructions

1️⃣ Preheat Oven

Preheat your oven to 350°F (175°C) and grease or line a baking dish (8×8-inch preferred).

2️⃣ Prepare the Brownies

Mix the brownie batter according to the package instructions.

Pour into the prepared dish, smoothing the top with a spatula.

3️⃣ Layer the Toppings

Sprinkle evenly with:

  • Graham cracker crumbs
  • Chocolate chips
  • Crumbled bacon

Gently press toppings into the surface of the batter.

4️⃣ Bake

Bake for 25–30 minutes, or until a toothpick inserted comes out with moist crumbs (not wet batter).

5️⃣ Add the Fluff

Let brownies cool for 5–10 minutes.

Then dollop marshmallow fluff over the top and use a knife or offset spatula to swirl it gently.

Optional: Place under the broiler for 30–60 seconds to toast the marshmallow.


🔥 Tips for Success

  • Cook the bacon crisp—no one wants chewy bits in a brownie.
  • Don’t overbake—fudgy brownies are better than dry ones.
  • Use a hot knife to slice cleanly through the marshmallow topping.

🍽 Serving Suggestions

These brownies are rich, so a little goes a long way. Try serving them with:

  • 🥛 A tall glass of cold milk
  • 🍦 A scoop of vanilla or salted caramel ice cream
  • 🍫 A drizzle of chocolate syrup for over-the-top decadence
  • 🍷 A bold red wine or smoky bourbon for grown-up s’mores vibes

🧊 Storage & Reheating

  • Room Temp: Store covered for 2–3 days.
  • Fridge: Extend shelf life to 5 days in an airtight container.
  • Freeze: Wrap individually and freeze up to 1 month—thaw at room temp.
