Recipe FAQs

Can I use whole marshmallows instead of fluff?

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.

How do I know when the bars are done cooking?

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.

How can I prevent the filling from coming out when cutting?

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.
