S’mores Bars

A soft, chewy S’mores bar loaded with milk chocolate chips and toasted marshmallows. These easy graham cracker blondies get topped with marshmallows and milk chocolate. Basically S’mores but no campfire required. 

I’m not sure there is anything more iconic than a S’mores in the summertime in America. Tell me I’m wrong. And yes just like most when it comes to summertime, I want all things S’mores.

But as much as I love a homemade S’mores on a bonfire these bars are a heck of a lot of easier. They have everything I love about a good S’mores – graham cracker base, ooey gooey milk chocolate, and toasted marshmallows on top. I took these to a 4th of July get together and they were devoured. And when I wish I had saved a couple for myself to take home, that’s how I know this recipe is a winner.

Why You Will Love These S’mores Bars

• Great Dessert For Summer Get Togethers – I love super easy bar desserts for the summer. I can make them ahead of time and they are easy to transport. Plus everyone wants one!
• Easier Than S’mores! – I love a good S’mores but these bars are much easier than building a bonfire!
• Quick To Mix Up – These are super fast to mix up and take about 25 minutes in the oven, so they make a great easy last minute dessert for all those summer parties.

Ingredients Needed

• Dry Ingredients: It’s a simple combination of all-purpose flour, graham cracker crumbs, baking powder, and salt. Now for the graham crackers, you can buy them, or try making Homemade Graham Crackers!
• Wet Ingredients: Unsalted butter, brown sugar, eggs, and vanilla.
• Topping: Milk chocolate chips (or Hershey’s Bars) and mini marshmallows (but you could also use large ones cut in half).

How To Make These S’mores Bars

Whisk together the flours, graham cracker crumbs, baking powder, and salt into a bowl. Set aside.

In a second mixing bowl, whisk together the melted butter, brown sugar, eggs, and vanilla.

Add the dry ingredients and mix until just combined.

Spread the batter into a prepared 9×13 pan and bake for about 22-25 minutes or until the top if set and golden brown. These bars may not appear to be done, but they will continue to set up once they cool.

If you continue to bake these until they “appear done” then you will surely overbake them. So trust me, take them out at 25 minutes.

Then add your chocolate. You can use milk chocolate chips or Hershey bars. I use the “fun size” kind but you can use large ones as well.

Then add the marshmallows! Now it’s time to broil. You want to set the bars back in the oven (I recommend the middle of the oven so they aren’t too close and burn) and broil for 1-2 minutes. You just want to get the marshmallows lightly toasted. Keep a close eye!

Recipe Tips

• Be sure to measure your flour correctly. Overmeasuring can result in a cakey texture instead fo the perfect chewiness that we are going for. You can get the full tutorial on how to measure your flour here.
• Make sure your ingredients are room temperature, like your eggs. To bring your eggs to room temperature quickly place them in a bowl of warm water for 10 minutes.
• Do not overbake. They may appear not done at this time, but taking them out during that time, ensures you won’t overbake them! 
• Watch The Broiler! Once the marshmallows are on and they are under the broiler. Be careful. They can burn quickly!

How To Cut These S’mores Bars: 

You could just bring the whole pan to your party and call it a day. No one would care once they taste one. But if you want to cut them into attractive bars here a few tips:

• Line Your Pan. First, line your pan with parchment paper and spray lightly with cooking spray. This will make it easier to simply lift out the entire pan at once and cut into bars.
• Allow them to cool. Completely. Cutting them warm is just going to end up in a GIANT disaster. Let them sit on the counter until they come to room temperature. I pop mine in the fridge to hurry up this process and help to firm up the bars before cutting. Usually at least an hour if not longer if I can wait that long!
• Use a knife lightly greased. Otherwise the marshmallow stick.
