S’mores Crack (Saltine Cracker Toffee with Graham Crackers, Chocolate, and Marshmallows)
S’mores Crack is an easy, irresistible dessert made with buttery brown sugar toffee layered over crackers, then topped with melted chocolate, gooey marshmallows, and graham crackers. It’s a fun twist on classic saltine cracker toffee with all the cozy flavors of s’mores—no campfire needed.
If you already love s’mores, this one just makes sense. It’s one of those flavor combinations that’s hard to mess up, and I had a feeling it would work really well in a saltine cracker toffee.
Honestly, it started as a craving. I wanted something sweet, a little nostalgic, and easy to throw together—and this checked all the boxes.
It’s delicious as-is with the chocolate, marshmallows, and graham crackers, but if you take a minute to torch the marshmallows at the end, it completely changes it. That toasted flavor makes it taste just like a real campfire s’more, and it’s so worth the extra step.

How to Make S’mores Crack – Overview
You can find the full recipe details, including ingredient amounts and the full instructions in the recipe card at the bottom of this post, but first, here's a quick overview of how to make S’mores Saltine Cracker Toffee!
This S’mores Crack starts with a layer of crackers (graham crackers or saltines) arranged on a baking sheet. A simple butter and brown sugar mixture is cooked into a rich, sticky toffee and poured over top, making sure everything is fully covered.
After a quick bake, chocolate chips are added and spread into a smooth layer. Then comes the best part—mini marshmallows and graham cracker pieces are sprinkled over top and gently tapped into place.
Once chilled and set, you can break the crack into pieces and enjoy it as-is, or take it a step further by lightly torching the marshmallows for that classic toasted s’mores flavor.
Recipe Variations & Substitutions
This S’mores crack is a fun twist on classic saltine cracker toffee, and the main variations come down to the crackers and how you finish it.
- Use graham crackers (like I did for this recipe and as shown in the photos) for a more classic s’mores flavor and a slightly richer, sweeter base
- Use saltine crackers if you prefer that sweet-and-salty contrast that traditional crack recipes are known for
- Torch the marshmallows for a toasted campfire flavor, or leave them as-is—both are delicious
No matter which option you choose, this recipe turns out great and is easy to adjust based on your preference or what you have on hand.
If you’ve seen my original saltine cracker toffee (crack) on Instagram, you already know how easy it is to customize with different toppings—I’ll be sharing even more variations soon!
Frequently Asked Questions
Why is my toffee soft instead of crunchy?
The toffee likely didn’t boil long enough. Make sure it bubbles for a full 3–4 minutes until thick and glossy—this helps it set properly.
Do I have to use graham crackers?
Nope! You can use saltine crackers if you prefer. Graham crackers (like in this recipe) give it a more classic s’mores flavor, while saltines add that sweet-and-salty contrast.
Do I have to torch the marshmallows?
Not at all. It’s delicious as-is, but torching the marshmallows adds that toasted, campfire flavor that really makes it taste like a true s’more.
What if my chocolate doesn’t spread easily?
Let it sit for a couple extra minutes after sprinkling it on. The heat from the toffee will soften it so it spreads smoothly.
Storage & Freezing
Storage:
Store the crack in an airtight container at room temperature for up to 5 days, or in the refrigerator if you prefer it firmer.
Freezing:
You can freeze it in an airtight container for up to 2 months. Let it sit at room temperature for a few minutes before serving so it’s easier to bite into.
What Can I Serve This With?
This S’mores crack is perfect on its own, but it’s also really fun to include as part of a bigger dessert spread. I love serving it alongside some of my other sweet treats like Nanaimo Bars or Oreo Truffles when I want a mix of textures and flavors.
It also pairs really well with something warm and cozy like coffee or hot chocolate, especially if you’ve taken the extra step to toast the marshmallows. If you’re putting together a holiday tray or bringing something to share, adding this in with a few other favorites like Butter Tart Squares or Peppermint Bark always works out really well.

Description
This S’mores Saltine Cracker Toffee is a simple, crowd-pleasing dessert made with layers of buttery toffee, melted chocolate, mini marshmallows, and graham crackers. It’s everything you love about s’mores in an easy, crunchy treat that’s perfect for sharing (or not!).
Ingredients
- 1 sleeve saltine crackers
OR enough graham crackers to cover a baking sheet (about 9–12 full graham crackers) - 1 cup unsalted butter
- 1 cup brown sugar (packed)
- 1 ½ cups milk chocolate chips (or semi-sweet)
- 1 ½ cups mini marshmallows
- 3–4 full graham crackers, broken into pieces
Instructions
- Preheat oven to 400°F and line a baking sheet with parchment paper. Arrange saltine crackers or graham crackers in a single layer to cover the sheet. (For the version shown in the photos, graham crackers were used.)
- In a saucepan over medium heat, melt the butter and brown sugar together.
- Bring to a boil and let it bubble for 3–4 minutes, stirring constantly, until thickened and glossy (almost like glue).
- Pour the toffee mixture evenly over the crackers and spread gently, making sure all crackers are covered.
- Bake for 5 minutes, until bubbly.
- Remove from the oven and immediately sprinkle chocolate chips over the top. Let sit for 2–3 minutes, then spread into an even layer.
- Sprinkle mini marshmallows and graham cracker pieces over top. Gently tap the tray on the counter to help everything settle into the chocolate without pressing.
- Chill in the refrigerator for about 1 hour, or until fully set.
- Break into pieces and serve.
Optional: Lightly toast the marshmallows with a kitchen torch for a toasted campfire-style flavor. If the chocolate softens while torching, place the tray back in the refrigerator for a few minutes to firm up again before breaking into pieces.
Notes
This version was made with graham crackers for a classic s’mores flavor, but saltines can be used for a sweet-and-salty variation.
Milk chocolate gives that traditional s’mores taste, but semi-sweet works well if you prefer less sweetness.
Don’t skip the full 3–4 minute boil—this is key for getting that crisp toffee texture.
Make sure all crackers are fully covered to prevent soggy spots.
Tapping the tray instead of pressing keeps the chocolate smooth and the toppings looking clean.
If you torch the marshmallows, the chocolate may soften slightly—just pop it back in the fridge for a few minutes to set again before breaking.
