S'mores Fudge Recipe with Marshmallow Topping (2)

This recipe has been on my website almost since the very beginning. It has been a favorite of readers for years. And I thought it was about time that this delicious fudge recipe got a face lift.

Based off my easy fudge recipe, we are adding in two other simple layers to make that classic s’mores taste that you know and love. While this is a layered fudge, I think you will still find it is super easy to make.

Reader Review

How to Make S’mores Fudge

This is a brief overview of how to make this delicious fudge recipe. For the full recipe with all of the measurements, please see the recipe card at the bottom of the post.

  1. Make the graham cracker layer. Combine graham cracker crumbs, a little sugar, and some melted butter together and then press into the baking dish. Bake for a few minutes.
  2. Make the chocolate layer. Combine half a can of sweetened condensed milk with chocolate chips. Melt together until smooth and pour over the graham cracker layer.
  3. Make the marshmallow topping. Combine white chocolate chips, the remaining sweetened condensed milk, and marshmallow fluff together. Melt until smooth. Pour it over the chocolate layer.
  4. Let it set. This works best if you refrigerate it overnight. Remove from the foil and then cut into pieces and enjoy.

S’mores Fudge Tips

  • Make sure you grab sweetened condensed milk and not evaporated milk. The two often are in the same exact sized can, and have similar labels. Its a very easy to make this mistake, but it will not make fudge.
  • Use brand name sweetened condensed milk. I feel like Eagle is your best bet, but the brand can make a real difference so avoid store brand.
  • Mix the sweetened condensed milk before using. Since we are essentially making two different fudges and sweetened condensed milk can separate, mixing it is key.
  • Do your best when measuring marshmallow fluff. It’s not easy to measure. I measure in a dry (plastic, not glass) measuring cup. Sometimes it helps to spray the measuring cup first.
  • Use quality chocolate. This will make for a smoother fudge. It doesn’t have to be high end, but again, avoid store bought.

Storing

Store this delicious easy fudge recipe in a single layer in an air tight container. It can be stored at room temperature and is best when eaten within two weeks. As with all recipes, use your best discretion when it comes to leftovers.

Freezing

This fudge is great to freeze. Place it in a single layer in the freezer for at least four hours. This will flash freeze the fudge. Then it can be stored in a container in layers with wax paper between each layer. Store in the freezer for up to three months.

Chocolate Fudge Layer

  • 1 1/2 cups milk chocolate chips (255 grams)

    Merry Christmas! I don’t have any marshmallow fluff but I have lots of small marshmallows. Can I use them instead for the SMores fudge?

      I’m so sorry, I have only tested this with marshmallow fluff. I would suspect that mini marshmallows would work, but I’d want to test it before telling you for sure.

    Hi Lisa,

    I’m not familiar with marshmallow fluff (maybe because I’m in Canada!). Could melted marshmallows be substituted?

    Thank you for showing the grams for each ingredient. I’ve recently started using them and it is so much easier than measuring.

    Looking forward to trying this. I’m not a baker or even a dessert maker but these really look too good not to try.

    I tried this over five times and each time the graham cracker crust fell off- no matter how careful I was- would egg help? What am I doing wrong?

      The crust is a bit flakey on this, for sure. But it does primarily stay on when I’m making this. So without being there I’m not sure what the issue is.

Why is my marshmallow fudge dry? ›

Too little time and the water won't evaporate, causing the fudge to be soft. Conversely, cook it too long and fudge won't contain enough water, making it hard with a dry, crumbly texture. Pay attention to the timetable specified in the recipe, and you'll get the hang of it after a batch or two.

Why is my 3 ingredient fudge not setting? ›

The main reason is that your Fudge has not reached the optimum temperature. If your mixture only reaches 110 or 112 degrees Celsius it will always be soft. That's why we recommend investing in a sugar thermometer. Another reason your Fudge is not setting is that the ratio of liquid to sugar is too high.

Why is my condensed milk fudge not setting? ›

It sounds like your fudge simply wasn't heated enough. Fudge is basically a superconcentrated syrup, and it sets when sugar dissolved in the water (from the butter and milk) comes out of solution as the mixture cools and forms crystals.

What is the secret to smooth fudge that is not gritty? ›

Once the sugar has dissolved and the mixture has come to a boil, do not stir it. If you do, the sugar can crystallize, giving your fudge a gritty texture. As you beat the fudge, pay attention to color and texture. Once the fudge loses its sheen and thickens, put down your spoon.

What makes high quality fudge? ›

You have to control two temperatures to make successful fudge: the cooking temperature AND the temperature at which the mixture cools before stirring to make it crystallize. Confectionery experiments have shown that the ideal cooking temperature for fudge is around 114 to 115 °C (237 to 239 °F).

What happens if you boil fudge too long? ›

Candy that isn't cooked long enough will end up too soft; overcooking makes fudge crumbly or hard. High-quality fudge has many small crystals. If the process of crystallization begins too early, fewer crystals form and they become much larger.

Can you fix fudge that didn't harden? ›

How can you fix soft fudge? Put it in a microwave safe bowl that is large enough that it won't boil over. Reheat it to the boiling point and cook for about 3 more minutes. Then you can beat some powdered sugar into it if this doesn't make it set.

How do you keep fudge moist? ›

Wrap your fudge in an air-tight container. Several layers of saran wrap, vacuum seal, Tupperware should all keep the moisture locked in pretty good.

What happens if you forget the vanilla in fudge? ›

There are lots of fudge recipes around which don't use vanilla at all (it's a treat which is very open to experimentation in general). So if you don't add vanilla, it won't taste like vanilla, but that doesn't necessarily mean it will taste bad, have the wrong consistency or behave differently when cooked and cooled.

Why do you add vanilla to fudge? ›

Vanilla is often added to chocolate candies or other chocolate recipes because it complements and accents the flavor of chocolate.

Why won't my marshmallow fudge set? ›

You do not want it to get too hot! Heating sugar to varying degrees has very different effects on how it behaves. Too much heat and your fudge will be dense and grainy. Not enough and it won't set.

Which is better for fudge evaporated or condensed milk? ›

Condensed milk is thicker and sweetened. If you want it to be the right consistency and flavor do not substitute. How can I make a fudge recipe without using evaporated milk? Evaporated milk is used to richen the texture of the fudge.

What happens if I use sweetened condensed milk instead of evaporated milk in fudge? ›

Use Evaporated Milk- Make sure to use evaporated milk and not sweetened condensed milk. If you accidentally use sweetened condensed milk your fudge will be incredibly over the top sweet. Cut up the Butter– Before adding the butter in make sure to cut it into smaller pieces for faster melting.

Why did my fudge turn out like caramel? ›

Fudge can turn into caramel due to overcooking or undercooking, incorrect temperatures, or wrong ingredients.

Should you stir fudge constantly? ›

It is important to stir constantly with a wooden spoon until the mixture starts to thicken and its surface starts to look dull or matte. Now is the time to stop beating and pour the fudge into a mould. Another tip: Do not scrape the sides of the pan or the spoon used for stirring.

What does cream of tartar do in fudge? ›

Cream of tartar is used in caramel sauces and fudge to help prevent the sugar from crystallizing while cooking. It also prevents cooling sugars from forming brittle crystals, this is why it's the secret ingredient in snickerdoodles!

How do you keep fudge smooth? ›

If the sugar crystals are not properly dissolved before cooling, they can create a gritty texture. To avoid this, ensure that you stir the fudge mixture consistently and remove any sugar crystals that form on the sides of the pan using a wet pastry brush.

What do I do if my fudge doesn't harden? ›

How can you fix soft fudge? Put it in a microwave safe bowl that is large enough that it won't boil over. Reheat it to the boiling point and cook for about 3 more minutes. Then you can beat some powdered sugar into it if this doesn't make it set.
