How to Make Nutella S’mores Bars
Step #1. Preheat the oven and prepare a square baking dish. In a food processor, add the graham crackers and blend until smooth. Add flour and salt, blend to combine.
Step #2. In a bowl, add the butter and brown sugar. Beat until light and fluffy. Add the vanilla and egg, then beat until well combined.
Step #3. Add the cracker crumb mixture and stir until just combined. Place the majority of the dough in the prepared dish and press it flat.
Step #4. Add the Nutella and spread it over the dough. Add the marshmallow fluff and spread to cover the Nutella. Place the remaining dough over top in small pieces. Bake until the bars are golden brown. Take them out and allow the bars to cool.
Recipe FAQs
We love using the fluff because it is easy to spread and ensures that you get the marshmallow taste in each bite. But, if you do not have marshmallow fluff, then marshmallows will give you the same taste and work just fine. I would recommend using mini marshmallows or chop them up if you have bigger ones. They should melt nicely while the bars bake, but it will have a slightly different texture than using the fluff, so keep that in mind.
These bars should be done within 35-40 minutes. You can check to see if they are done by inserting a toothpick to the middle of the bars. If it comes out clean with no cookie dough stuck to it, then they are ready! You can also look at the color of the bars, the top and edges should have a golden-brown color. Be careful not to overcook the bars otherwise they can become dry, so check them at the 35 minute mark and go from there.
For a nice clean cut, it is important to allow the bars to cool completely before cutting. This might take a little planning ahead, but you should wait at least 4 hours. The bars will still be gooey and warm, but it will be easier to cut them without the filling spilling all over the place. Additionally, you can place the pan in the fridge overnight before cutting if you want the bars to have an even more clean and precise cut.
How to Store Nutella S’mores Bars
If you happen to have any leftover s’mores bars, they should be kept in an airtight container in the fridge for up to 1 week. You can allow them to come to room temperature before enjoying, or place them in the microwave on a plate for 15-20 seconds to make the middle warm and gooey before eating!
Expert Tips
- To prepare the pan, you can either spray it with cooking spray or use a foil sling to remove the bars as a whole, then cut afterward.
- If you do not have unsalted butter, you can use salted butter and just skip the ½ teaspoon of salt.
- To give your bars a little different flavor, you can replace the Nutella with ½ cup peanut butter and ½ cup chocolate chips for a rich and bold taste!
- Once you add the dough pieces on top, you will probably see marshmallow fluff poking out, which is completely normal and totally fine.

Nutella S’mores Bars
Ingredients
- 9 full-sized graham crackers, 1 sleeve, about 5 oz
- 1 cup + 2 tablespoons all-purpose flour
- 1/2 teaspoon salt
- 2 sticks unsalted butter, (1 cup), at room temperature
- 2/3 cup brown sugar
- 1 teaspoon vanilla extract
- 1 large egg
- 1 cup Nutella
- 1 jar marshmallow fluff, (7 oz)
Instructions
- Preheat the oven to 350 degrees and spray an 8 inch square baking dish with cooking spray, or make a foil sling and spray the foil with cooking spray (If you want to take the bars out of the pan to cut and serve I’d use the foil sling. If you plan on serving out of the dish, then you can skip that step).
- In a food processor or a blender add the graham crackers and blend until you have made smooth crumbs.
- Add the flour and salt and blend to combine.
- In a medium bowl or the bowl of your stand mixer add the butter and brown sugar and beat until light and fluffy, about 3 minutes.
- Add the vanilla and the egg and beat until well combined. Add the cracker crumb mixture and stir until just incorporated.
- Place 2/3 of the dough in the bottom of the prepared dish and press it flat with your hands or the bottom of a greased measuring cup.
- Add the Nutella and spread if around to cover the dough. Add the marshmallow fluff and spread it around to cover the Nutella.
- Place the remaining dough over the top in small pieces, it’s ok if you can see marshmallow fluff poking out.
- Bake for 35 to 40 minutes until a toothpick inserted in the center comes out with no cookie dough stuck to it.
- Let the bars cool before serving. If you are planning on removing them from the pan to cut and serve let them cool at least 4 hours before cutting.
Notes
- No Nutella on hand, replace it with 1/2 cup peanut butter and 1/2 cup chocolate chips. SO GOOD!
Although I’m Horrified that 1/12 th of the recipe has @499 calories, these bars are extremely, unreasonably Yummy. My grandsons had fun making this on a rainy summer day we were stuck inside. I explained it called for Lego or Video game skills. Don’t know they Bought the analogy, or we’re just humoring me.

Melissa you are an evil diet saboteur. I seriously gained weight just reading the recipe. Going to have to try it. I love you to pieces.
How much would it be if I used the pre-crushed graham crackers? Thanks!
Hmmm? Maybe a little more than a cup? It’s about 5 ounces in weight.

Yum! I love Nutella. I have the giant “happy” sized jar in my cabinet. My favorite combo is Fritos and Nutella. Seconded by Pretzels and Nutella.
These sound sinfully delicious! And I don’t know how I’ve never tried Nutella with pretzels, but that is going to be my afternoon snack today!
Eat all the Nutella S’mores!!!!
