These s’mores toffee bars are absolutely addicting! They start with a graham cracker base, then they’re topped with a caramel-y toffee layer. Then that’s topped with a good amount of mini marshmallows and milk chocolate. It’s like s’mores with a salted caramel addition and without the need for a campfire! And they’re pretty quick and easy to make too!

I first made these way back in 2012 and had shared them on my old blog. I recently stumbled upon the recipe and realized I had forgotten about them and hadn’t made them in years. Such a tragedy, I decided I needed to remedy that quickly and thought they should be shared here with you!

I did tweak the recipe a tiny bit, since my baking skills have grown and changed over the years since I first started making them. The best addition – sea salt flakes in the caramel toffee layer. These bars had always been so good, but just always felt a little bit like they were missing something. I had switched to using salted butter years ago, but I still felt like they needed something. When I read through my old recipe, I immediately thought of sea salt flakes and knew I had to try it. And it was magic. Exactly what these delicious bars needed.

Tips for making S’mores Toffee Bars:

I always like to use sea salt flakes in my dessert recipes. It’s just a slightly better tasting salt and isn’t as overwhelming as regular table salt. I highly recommend it. If you use regular table salt, you may need to adjust the amount you’re putting in.
For the chocolate, I stick with milk chocolate, just to keep it as close as possible to traditional s’mores. But you can sub whatever type of chocolate you like! There’s a mix of Hershey bars and chocolate chips in this. I like to use a mix of chocolate chips and chopped milk chocolate for the chocolate chip portion.

S’mores Toffee Bars

Graham crackers covered with salted caramel-y toffee, chocolate and marshmallows. An easy to make dessert that's so addictive!

Course: Dessert

Ingredients

10-12 sheets of graham crackers (amount will vary, depending on the size pan you use)
1 cup salted butter
1 cup brown sugar
1 teaspoon pure vanilla extract
1 teaspoon sea salt flakes*
4 cups mini marshmallows
4 Hershey chocolate bars, broken into pieces
1 cup milk chocolate chips or chopped milk chocolate

Instructions

Preheat oven to 350°F. Line a 12x16x1-inch (or similar size) baking sheet with parchment paper, leaving a 1-inch overhang over the ends.
Line graham crackers up on the parchment paper so that the sides are touching. Make sure the entire bottom of the pan is covered – I break mine up near the edges to squeeze them in.
(10-12 sheets of graham crackers)
In a medium saucepan, melt the butter and brown sugar over medium heat, stirring constantly, until smooth and mixture comes just to a boil, about 5 minutes. Remove from heat.
(1 cup salted butter, 1 cup brown sugar)
Stir in vanilla and sea salt flakes and pour evenly over crackers. Bake 5 to 6 minutes, or until bubbly.
(1 teaspoon pure vanilla extract,1 teaspoon sea salt flakes*)
Remove pan from oven and immediately sprinkle mini marshmallows, chocolate bar pieces, and chocolate chips over the crackers.
(4 cups mini marshmallows, 4 Hershey chocolate bars, 1 cup milk chocolate chips or chopped milk chocolate)
Return pan to oven for another 3-5 minutes, or until marshmallows begin to soften and puff up.
Remove from oven.
If you'd like to brown the marshmallows a bit more, set oven to broil. Give your oven a couple of minutes to heat up to broil if it needs it. Return pan to oven and broil for 30-60 seconds, or however long it takes to get nice & golden – watch carefully!
Cool completely.
Lift from pan; cut into bars and enjoy!

Recipe Notes

*I have only made this recipe with sea salt flakes. If you are using regular table salt, the amount may need to be reduced.
