Essential Ingredients

  • 1 package graham crackers, crushed
  • 1/2 cup sugar
  • 6 tablespoons butter, melted
  • 1 1/2 cups flour
  • 1 teaspoon baking powder
  • 1/2 cup cocoa
  • 1 cup butter, softened
  • 2 cups sugar
  • 2 teaspoons vanilla
  • 3 eggs
  • 1/4 cup milk
  • 10 ounces mini marshmallows
  • 1/2 cup chocolate chips
  • 1/2 cup peanut butter chips
  • 1 cup mini peanut butter cups, chopped

Preparation Steps

  1. Preheat & Prep:
    Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch glass baking dish with non-stick spray.
  2. Graham Cracker Crust:
    Combine crushed graham crackers, melted butter, and 1/2 cup sugar. Mix and press into the baking dish. Set aside.
  3. Brownie Batter:
    • Cream together softened butter and sugar until light and fluffy.
    • In another bowl, whisk flour, baking powder, and cocoa. Gradually combine with butter mixture.
    • Stir in vanilla and milk.
    • Add eggs one at a time, mixing well.
    • Fold in chopped mini peanut butter cups.
    • Spread the batter evenly over the crust.
  4. Bake:
    Bake for 22–25 minutes or until set in the center.
  5. Topping & Broil:
    Set oven to low broil. Top brownies with marshmallows, chocolate chips, and peanut butter chips. Broil until the marshmallows are golden (about 1–2 minutes—watch closely!).
  6. Cool & Serve:
    Let the brownies cool for 5–10 minutes before slicing and serving.

Health Benefits

While indulgent, these brownies offer a few perks:

  • Peanut butter adds healthy fats and a small dose of protein.
  • Dark chocolate chips (if used) may contain antioxidants.
  • Homemade quality means you control the ingredients—fewer additives than packaged desserts.

Serving Suggestions

  • Serve warm with vanilla ice cream for the ultimate comfort dessert.
  • Add a drizzle of chocolate or caramel sauce for extra decadence.
  • For gatherings, cut into small squares and serve on a tray with toothpicks for easy snacking.

Creative Variations

  • Nut-Free: Use sunflower seed butter and omit peanut butter cups.
  • Gluten-Free: Use gluten-free graham crackers and flour.
  • Chocolate Overload: Add white chocolate chips or swirl in Nutella.
  • Fruit Twist: Add sliced bananas or a layer of raspberry jam before baking.

Storage Tips

  • Store leftovers in an airtight container at room temperature for up to 3 days.
  • Refrigerate for longer freshness—up to 1 week.
  • Freeze sliced bars (wrapped individually) for up to 2 months. Thaw before serving or warm in the microwave.

Pro Tips

  • Always keep an eye on the broiler—marshmallows brown fast!
  • Use parchment paper in your pan for easy removal and cleaner slices.
  • Let brownies cool slightly before slicing for cleaner cuts and easier serving.
