Fun Fact: Did you know that the first s’mores recipe came out in 1927? The Girl Scouts came out with a guidebook, “Tramping and Trailing with the Girl Scouts,” featuring the first ultimate outdoorsy treat recipe. They’ll have you coming for one and then s’more - a lot more!

Can You Make These Chewy S’mores Brownies Ahead of Time?

Yes! It’s a great idea to make these brownies a day before a party or a get-together so that they can cool and you’re able to cut them. However, they won’t be as delicious after a couple of days.

Can I Use Boxed Brownie Mix?

Of course! While I recommend homemade brownie mix, boxed mix will work in a pinch. Use your favorite boxed mix, prepare mix as directed, and then follow Step 3. Make sure that you get a brownie mix that works for an 8x8 pan. Try this one here!

What Is the Best Way to Cut These Scrumptious S’mores Brownies?

To cut the brownies when they are warm, I recommend spraying the knife with cooking spray to prevent sticking. If you decide to cut them while they are cold, I would wipe off the blade between slices. You could also run the blade under warm water to help keep the chocolate and marshmallow from sticking.

What Is the Best Way to Store These Easy S’mores Brownies?

I recommend storing your brownies in a tightly covered pan or in an airtight container. They can be kept in the pan at room temperature for up to 3 days. Keep in mind that the longer you wait to devour these brownies, the softer the graham cracker will get. 

Can I Substitute the Hershey’s Chocolate Bars?

Yes! You are welcome to use chocolate chips instead of Hershey’s Chocolate Bars. I recommend around a cup of chocolate chips. Try substituting the Hershey’s Chocolate Bars for Reese’s Peanut Butter Cups - talk about delicious!

What Kind of Pan Should I Use?

I recommend using an 8x8 metal baking pan. I use nonstick baking spray for this recipe, but I have also seen people use parchment paper to make it a little easier to come out and for a quicker clean-up. You can also use disposable baking pans for parties, and they are perfect for gift giving. 

These easy-to-make s’mores can be an easy weeknight treat or just the perfect cure for your sweet tooth. Whatever the case - we know you’ll be wanting s’more!

Prep Time: 10 mins
Cook Time: 50 mins
Calories: 421kcal

Ingredients

  • ½ cup unsalted butter, melted
  • 2 tbsp vegetable oil
  • 1 cup sugar
  • ½ cup brown sugar
  • 2 eggs
  • ½ cup sour cream
  • 1 tsp vanilla extract
  • 1 cup all purpose flour
  • ¾ cup cocoa powder
  • ½ tsp kosher salt
  • 6 graham cracker sheets, broken into pieces
  • 10-15 large marshmallows
  • 1 Hersheys chocolate bar, broken into pieces

Directions

  • Preheat the oven to 350 degrees. In a large bowl, mix together whisk eggs and then add butter, sugar, and brown sugar. Continue to whisk for about 2 minutes. Then add sour cream and vanilla extract and mix until combined and smooth.
  • Add flour, cocoa powder, and kosher salt and fold together until a thick batter forms.
  • Spray an 8x8 baking pan with nonstick baking spray. Add 1 cup of the batter to the pan and spread to create an even layer.
  • Using your hands, roughly break up 3 graham cracker sheets and sprinkle them on top of the bottom layer, then place 5 marshmallows into the batter. Then add ½ of the chocolate bar pieces.
  • Add the remaining brownie batter on top (it’s ok if the batter does not cover the marshmallows). Once the batter is added, add the remaining marshmallows and broken graham cracker pieces and chocolate bar pieces on top.
  • Bake for 50 minutes. Allow brownies to cool in the baking pan for 15 minutes then remove onto a cooling rack or plate to cool completely.
