Ingredients
Blondie S’mores Bars – a merging of two all time favorite sweet treats, blondies and good old fashioned s’mores.
For the Blondie Base
- 6 tablespoons butter
- ¾ cup light brown sugar
- 1 large egg
- 2 teaspoons vanilla extract
- ¾ cup all purpose flour
- ½ teaspoon baking powder
- ¼ teaspoon kosher salt
For the Topping
- 1 1/2 cups milk chocolate chips or 4-5 Hershey 1.55-ounce candy bars
- 3 cups miniature vegan marshmallows
- 1-2 1.55-ounce bar Hershey milk chocolate candy bars (cut into individual squares)
How to Make Blondie S’Mores Bars
Step 1: Preheat the Oven
Adjust oven rack to the middle position; heat oven to 350° F. Spray an 8-inch pan with cooking spray or lightly grease it with oil. Cut an 8 x14-inch strip of foil and line the pan with it, allowing the long sides to extend over the top. This will help you remove the bars easily later on.
Step 2: Melt Butter
In a medium-large saucepan, heat butter until just melted. Remove from heat and let cool slightly for a few minutes.
Step 3: Combine Wet Ingredients
Whisk in light brown sugar, mixing until well combined. Add in the egg and vanilla extract, stirring to incorporate everything evenly.
Step 4: Mix Dry Ingredients
Add together all-purpose flour, baking powder, and kosher salt. Using a rubber spatula, stir just until combined; do not overmix to keep your blondies chewy.
Step 5: Bake
Pour the mixture into the prepared pan. Bake until the top is shiny, cracked, and light golden brown—about 18 to 22 minutes. Be careful not to overbake!
Step 6: Broil Topping
Set aside to cool for about 10 minutes. Preheat your broiler on high with a rack set 6-8 inches from it. Top blondies with chocolate chips or lay candy bars across them before sprinkling with vegan marshmallows. Broil for approximately 30 seconds to one minute until they start to brown—keep a close eye on them!
Step 7: Finish Up
Remove from oven and cool for another 10 minutes before adding pieces of Hershey bar across the top randomly. Let cool completely before cutting into squares using a lightly oiled sharp knife.
Enjoy these scrumptious Blondie S’Mores Bars as an indulgent treat anytime!

Common Mistakes to Avoid
When making Blondie S’Mores Bars, it’s easy to overlook key steps. Here are some common mistakes to watch for.
- Using cold butter: Always melt the butter and let it cool a bit before mixing. Cold butter can lead to uneven texture.
- Overmixing the batter: Once you add the flour, mix just until combined. Overmixing can create dense bars instead of light blondies.
- Skipping the cooling time: Allowing the bars to cool for 10 minutes helps set them properly before adding toppings. Skipping this step can result in a messy finish.
- Not watching the broiler: When browning the marshmallows, keep a close eye on them. They can burn quickly, turning your treat from delicious to disastrous.
- Ignoring cutting tips: Use an oiled knife when cutting the bars for clean edges. A dry knife may stick, ruining the shape of your squares.
