  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.

  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.

  • Total Time: 50 minutes (including cooling time)

Ingredients

Scale

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

Instructions

First, let’s preheat that charming oven of yours to a cozy 350 degrees Fahrenheit. Don’t forget to lightly spray a 9 x 13 glass baking dish with non-stick cooking spray to ensure our brownies don’t stick! Now, on to the crust—take your crushed graham crackers and combine them in a bowl with melted butter and half a cup of sugar. Mix them together with your hands or a fork, then press it evenly into the bottom of your baking dish. Set this delightful crust aside!

Next up, let’s make the brownies! In a large bowl, cream together the softened butter and sugar until the mixture is light and fluffy, almost like a cloud! In a separate bowl, whisk together the flour, baking powder, and cocoa. Gradually add this dry mixture to the buttery goodness, stirring well with an electric mixer.

Don’t forget to stir in the milk and vanilla, giving it that lovely flavor. Next, add the eggs one by one, ensuring to mix well after each addition. Now comes the fun part—fold in those little mini peanut butter cups! Pour this beautiful brownie batter over your prepared graham cracker crust, spreading it lovingly to cover every inch. Place it in the oven and bake for 22-25 minutes until it is beautifully set in the middle.

 

When those brownies come out, switch your oven to broil on low. Top your warm brownies with mini marshmallows, chocolate chips, and peanut butter chips. Pop it back into the oven just until the marshmallows start to brown and everything becomes gooey. Be sure to keep an eye on it to avoid any burnt bits! Once done, let it cool for about 5-10 minutes before you dive in.
