S’mores Brownies Recipe
Introduction
These S’mores Brownies bring the classic campfire treat indoors with a rich chocolate twist. Layers of graham crackers, chocolate, and toasty marshmallows make every bite delightfully gooey and satisfying. Perfect for a cozy dessert or sharing with friends.

Ingredients
- Cooking spray
- 6 to 7 graham crackers
- 1 (18.3-oz.) box brownie mix, plus ingredients called for on box
- 3 (1.55-oz.) Hershey bars, chopped (about 1 cup)
- 1 (12-oz.) bag marshmallows
Instructions
- Step 1: Place a rack in the upper third of the oven and preheat to the temperature indicated on the brownie mix box. Spray a 9″ x 9″ baking pan with cooking spray. Arrange graham crackers in a single, trimmed layer to cover the bottom of the pan.
- Step 2: Prepare the brownie mix according to the package directions. Fold the chopped Hershey’s bars into the batter. Pour the batter evenly over the graham cracker layer and spread to cover.
- Step 3: Bake the brownies for the time recommended on the package, or until a tester inserted into the center comes out clean.
- Step 4: Remove the pan from the oven and set the broiler to high. Evenly arrange marshmallows over the top of the baked brownies.
- Step 5: Broil the marshmallows, watching carefully, until they turn golden brown, usually 1 to 2 minutes. Remove immediately to prevent burning.
- Step 6: Allow the brownies to cool at least 15 minutes before slicing. For cleaner cuts, spray a knife with cooking spray before slicing into pieces.
Tips & Variations
- For extra gooeyness, use mini marshmallows and spread them densely over the brownies before broiling.
- Try adding a sprinkle of sea salt over the marshmallows to enhance the chocolate flavor.
- Substitute the Hershey bars with your favorite chocolate chips or chunks for a different twist.
Storage
Store the S’mores Brownies in an airtight container at room temperature for up to 3 days. To keep marshmallows soft, avoid refrigeration. Reheat gently in a microwave for about 10 seconds if desired.

FAQs
Can I use homemade brownie batter instead of boxed mix?
Yes, homemade brownie batter works well. Just fold in the chopped chocolate and follow the same layering and baking steps.
What if I don’t have a broiler?
If you don’t have a broiler, you can place the brownies under a very hot oven for a few minutes or use a kitchen torch to toast the marshmallows carefully.

Ingredients
Base Layer
- 6 to 7 graham crackers
Brownie Batter
- 1 (18.3-oz.) box brownie mix
- Ingredients called for on brownie mix box (likely eggs, oil, and water as per standard)
- 3 (1.55-oz.) Hershey bars, chopped (about 1 cup)
Topping
- 1 (12-oz.) bag marshmallows
- Cooking spray (for pan and knife)
Instructions
- Preheat and Prepare Pan: Place an oven rack in the upper third of the oven and preheat to the temperature specified on the brownie mix box. Spray a 9″ x 9″ baking pan with cooking spray. Break and layer graham crackers at the bottom of the pan in a single layer, trimming pieces to fit as needed.
- Prepare Brownie Batter: Follow the brownie mix package instructions to prepare the batter, then fold in chopped Hershey bars evenly to infuse the brownies with chocolate chunks.
- Layer and Bake: Pour the brownie batter over the graham cracker base in the pan, spreading it evenly. Bake according to the time guidelines on the brownie box until a toothpick inserted in the center comes out clean.
- Add Marshmallow Topping: Remove the baked brownies from the oven, then turn the oven broiler to high. Immediately arrange marshmallows in an even layer over the hot brownies.
- Broil Marshmallows: Place the pan under the broiler, watching very closely—marshmallows will go from golden to burnt within a minute or two. Broil until marshmallows achieve a golden brown color, then promptly remove the pan from the oven.
- Cool and Serve: Let the brownies cool for at least 15 minutes or until completely cool. To slice, spray a knife with cooking spray for clean cuts and cut into pieces for serving.
Notes
- Use a 9″ x 9″ baking pan for best results.
- Keep a close eye during broiling as marshmallows brown very quickly.
- You can substitute regular marshmallows with mini marshmallows for a different texture.
- Allow brownies to cool completely so layers set well before slicing.
- For an extra gooey texture, add some extra chocolate chunks inside the batter.
