Crunchy Halloween S’mores Chex Mix with Marshmallows and Grahams

Here is my favorite Halloween s’mores chex mix recipe, with crunchy cereal, gooey marshmallows, sweet graham crackers, and all the classic s’mores flavors in one easy snack mix.

This Halloween treat is always the first thing to disappear at our fall parties. I usually make a double batch because my kids and their friends can’t stop munching on it. It’s like having a campfire right in your kitchen, but way easier to make!

What Kind of Chex Cereal Should I Use?

For this Halloween s’mores mix, you’ll want to stick with the classic Rice Chex and Wheat Chex combination as called for in the recipe. Rice Chex gives you that light, crispy crunch, while Wheat Chex adds a bit more substance and a slightly nuttier flavor that pairs well with the s’mores theme. You can find both varieties in the cereal aisle of pretty much any grocery store, and they’re usually sold right next to each other. If you can only find one type or want to simplify your shopping, you can absolutely use 8 cups of just Rice Chex or just Wheat Chex instead of mixing them – the recipe will still turn out great.

Options for Substitutions

This fun Halloween treat is pretty forgiving when it comes to swaps and substitutions:

• Rice and Wheat Chex cereal: You can mix and match any Chex varieties you have on hand – Corn Chex, Chocolate Chex, or even all of one type works great. The total should still be about 8 cups of cereal.
• White candy melts: White chocolate chips work as a substitute, though they may not coat as smoothly. You can also use vanilla almond bark or white chocolate baking squares – just melt them the same way.
• Golden Grahams cereal: If you can’t find Golden Grahams, try Cinnamon Toast Crunch or even crushed graham crackers (about 1 cup). Honey Nut Cheerios can work too for that sweet crunch.
• Dark cocoa candy melts: Regular chocolate chips, dark chocolate chips, or even melted chocolate bars will do the trick. Semi-sweet chocolate works perfectly for drizzling over the mix.
• Miniature marshmallows: Regular marshmallows cut into smaller pieces work fine, or you can use freeze-dried marshmallows for extra crunch. Marshmallow bits from the baking aisle are another good option.

Watch Out for These Mistakes While Cooking

The biggest mistake when making this s’mores Chex mix is overheating your candy melts, which can cause them to seize up and become thick and clumpy – always melt them in 30-second intervals in the microwave, stirring between each round until smooth.

Another common error is adding the powdered sugar while the cereal mixture is still too warm, which will cause the sugar to dissolve instead of creating that perfect dusty coating you want.

Make sure to work quickly once you’ve melted the candy coating since it hardens fast, and don’t dump all the cereal in at once – add it gradually and toss gently to ensure even coverage.

For the best results, let the mixture cool completely on parchment paper before adding the marshmallows, as they’ll melt if added too soon and create a sticky mess.

What to Serve With Halloween S’mores Chex Mix?

This sweet and crunchy mix is perfect for Halloween parties and pairs great with hot chocolate or apple cider to keep the cozy fall vibes going. You can set it out in bowls around your party space alongside other Halloween treats like candy corn, chocolate-covered pretzels, or pumpkin-shaped cookies. For movie nights, serve it with some popcorn and let everyone mix and match their favorite snacks. Since it’s already packed with all those s’mores flavors, it’s really the star of the show and doesn’t need much else – just grab some napkins because it can get a little messy!

Storage Instructions

Keep Fresh: This Halloween s’mores mix stays crunchy when stored in an airtight container at room temperature for up to one week. I like to use a big glass jar or plastic container with a tight lid to keep all that chocolatey goodness from getting stale. Just make sure it’s completely cooled before sealing it up!

Freeze: You can freeze portions of this mix in freezer bags for up to 2 months if you want to make it way ahead for Halloween parties. The marshmallows might get a little chewy after freezing, but the cereal and chocolate coating hold up really well.

Serve: This mix is best enjoyed straight from the container at room temperature. If you’ve frozen some, just let it thaw for about 10 minutes before serving. The chocolate coating might look a little cloudy after thawing, but it still tastes great and the kids won’t even notice!

Ingredients

For the coated snack mix:

• 4 cups wheat squares cereal (such as Wheat Chex)
• 4 cups rice squares cereal (such as Rice Chex)
• 1 1/2 cups confectioners’ sugar (sifted to remove lumps)
• 8 oz white confectionery coating wafers (melted and cooled slightly)

For the topping:

• 2 cups graham-flavored cereal squares (such as Honey Nut Chex)
• 2 oz dark cocoa flavored candy wafers (melted for drizzling)
• 1 cup mini marshmallows (Halloween colored preferred)

Step 1: Combine and Coat Cereal with White Chocolate

• 4 cups rice squares cereal
• 4 cups wheat squares cereal
• 8 oz white confectionery coating wafers

In a large bowl, combine the rice squares cereal and wheat squares cereal together.

In a separate microwave-safe bowl, melt the white confectionery coating wafers in 30-second intervals, stirring between each interval until completely smooth and slightly cooled (about 1-2 minutes of cooling helps prevent the coating from clumping the sugar later).

Pour the melted white chocolate over the cereal mixture and stir thoroughly with a spatula or wooden spoon until every piece is evenly coated.

Work quickly but carefully to ensure even distribution.

Step 2: Sugar-Coat and Dry the Mix

• coated cereal mixture from Step 1
• 1 1/2 cups confectioners’ sugar

Transfer the coated cereal from Step 1 into a large zip-top bag and add the sifted confectioners’ sugar.

Seal the bag securely and shake vigorously for 2-3 minutes until all the cereal pieces are evenly coated with the white chocolate and sugar mixture.

I like to hold the bag at the top and shake it in a vigorous up-and-down motion—it’s more effective than side-to-side shaking.

Spread the coated mix in a single layer on a large baking sheet or parchment paper and let it cool at room temperature for 10-15 minutes, stirring occasionally to prevent clumping.

Step 3: Add Graham Cereal and Marshmallows

• cooled sugar-coated cereal from Step 2
• 2 cups graham-flavored cereal squares
• 1 cup mini marshmallows

Once the sugar-coated mix has cooled completely and feels crispy to the touch, sprinkle the graham-flavored cereal squares and mini marshmallows evenly over the top.

Gently fold these ingredients into the chex mix using a large spoon or spatula, being careful not to crush the cereal or break apart the marshmallows.

I find that a gentle folding motion rather than stirring helps preserve the texture of both components.

The mix should still be slightly warm so the marshmallows soften slightly and adhere without melting completely.

Step 4: Drizzle with Dark Chocolate and Cool

• chex mix with marshmallows from Step 3
• 2 oz dark cocoa flavored candy wafers

Melt the dark cocoa flavored candy wafers in a microwave-safe bowl in 20-30 second intervals, stirring between each interval until completely smooth.

Allow to cool for 1-2 minutes so it thickens slightly and becomes drizzle-able.

Using a fork or small spoon, drizzle the melted dark chocolate over the chex mix from Step 3 in thin, decorative lines.

Spread the mixture back out on the baking sheet or parchment paper and let cool completely at room temperature for at least 15-20 minutes until the chocolate is set and the mixture feels completely crispy.

Step 5: Store and Serve

• finished chex mix from Step 4

Once completely cooled, break apart any large clumps gently with your hands and transfer to an airtight container or festive Halloween bag for serving.

The chex mix will stay crispy for up to 5 days when stored properly in an airtight container.
