Ingredients You’ll Need
The magic behind this Addicting Toffee Chex Mix lies in its simple but essential ingredients. Each one is chosen not just for flavor but for how it contributes to the texture, color, and overall irresistible character of the mix.
- 8–9 cups Chex cereal (Rice Chex or mix of Rice & Corn): Provides the perfect, light crunch as the delicious base for the toffee coating.
- 1 1/2 cups nuts (pecan halves or walnuts): Adds a toasty, buttery crunch that balances sweetness with a satisfying nutty bite.
- 1 cup unsalted butter (226 g / 2 sticks): The richness that makes the toffee so smooth and decadent.
- 1 1/2 cups packed brown sugar (light or dark): Gives the recipe its deep caramel flavor and lovely amber color.
- 1/2 cup light corn syrup: Ensures the toffee mixture stays silky and glossy without crystallizing.
- 1 tsp vanilla extract: Adds warmth and rounds out the buttery caramel notes perfectly.
- 1 tsp baking soda: Creates that classic toffee brittle texture by introducing lightness and airiness.
- 1/2 tsp fine salt: Enhances all the flavors and adds the perfect touch of balance to sweetness.
How to Make Addicting Toffee Chex Mix (Crispy Caramel Brittle) Recipe
Step 1: Preheat & Set Up
Start by preheating your oven to a gentle 250°F (120°C). Line your baking sheet or two with parchment paper so the toffee mix doesn’t stick and cleanup is easy. Next, grab a very large, heatproof bowl and combine the 8 to 9 cups of Chex cereal with the nuts. Setting your bowl near the stove and warming it lightly under hot water (then drying it) helps prevent the toffee syrup from seizing when you pour it later. This little trick makes all the difference for a smooth, crisp coating.
Step 2: Boil the Toffee
In a medium saucepan, melt together the butter, brown sugar, and light corn syrup over medium-high heat, stirring steadily until everything is smooth and combined. Then bring that mixture to a rolling boil and let it bubble without stirring for a full five minutes. It’s best to use a pan with tall sides here since the mixture will bubble up quite a bit once we add the baking soda.
Step 3: Create the Toffee Reaction
Remove the saucepan from heat and quickly whisk in the vanilla extract, salt, and baking soda. This step is pure magic because the baking soda causes the mixture to foam and puff up, turning a rich dark caramel into a lighter, crispy brittle texture — exactly what makes this Addicting Toffee Chex Mix (Crispy Caramel Brittle) Recipe so special. Watch out for those hot sugar bubbles; they can be sneaky!
Step 4: Coat the Mix (Work Quickly)
Immediately pour that beautiful foaming syrup over your cereal and nuts, then use a silicone spatula to toss and fold as quickly as possible. The goal is to get every piece glossy and fully coated with toffee sauce, scraping the bottom and sides so nothing dries out. This quick folding ensures every bite will have that perfect balance of sweet brittle and crunchy cereal.
Step 5: Bake the Addicting Toffee Chex Mix
Spread your coated mixture evenly over the lined baking sheet(s). Pop it into the preheated oven and bake for 45 to 60 minutes, stirring every 15 minutes to redistribute the syrup and ensure even crispness. Baking slowly at this low temperature dries out the toffee, giving your mix a satisfyingly crisp brittle texture rather than a sticky mess.
Step 6: Cool, Break & Store
Once baked, allow the mix to cool completely on the pan for 30 to 45 minutes — this is when the magic truly sets in as the brittle hardens. After cooling, break it gently into bite-sized shards. Keep your Addicting Toffee Chex Mix (Crispy Caramel Brittle) Recipe fresh by storing it in an airtight container at room temperature for up to a week. If you’re feeling generous, pack it into cellophane bags and sprinkle a little flaky sea salt on top for a gourmet finishing touch perfect for gifting.

Make Ahead and Storage
Storing Leftovers
Once your toffee mix has cooled completely, place it in an airtight container at room temperature. It will stay crisp and delicious for up to a week, making it a perfect snack to enjoy throughout the week or a thoughtful homemade gift that stays fresh.
Freezing
If you want to keep your Addicting Toffee Chex Mix (Crispy Caramel Brittle) Recipe longer, freezing works well. Place the cooled brittle in a freezer-safe container or ziplock bag, and it will keep for up to 3 months. Just be sure to thaw it at room temperature before serving to retain its crispy texture.
Reheating
To refresh a slightly stale batch, spread the brittle on a baking sheet and warm it in a 250°F oven for 5 to 10 minutes. This quick reheating re-crisps the brittle without melting the toffee, bringing back that fresh, buttery crunch like it was just made.
FAQs
Can I use different types of nuts in this recipe?
Absolutely! While pecans and walnuts are classic choices, feel free to experiment with almonds, cashews, or even mixed nuts depending on your preference. Just make sure they are unsalted or lightly salted to balance the sweetness perfectly.
What is the purpose of baking soda in the recipe?
The baking soda reacts with the hot sugar mixture to create tiny air bubbles, which lighten and crisp the toffee. This reaction gives the brittle its classic airy crunch and prevents it from becoming overly dense or hard.
Can I make this recipe gluten-free?
Yes, as long as you choose gluten-free Chex cereals (like Rice Chex) and double-check your other ingredients, this recipe can easily be gluten-free, making it a fantastic treat for those with sensitivities.
Why do I need to stir the toffee mix every 15 minutes while baking?
Stirring redistributes the toffee coating evenly and encourages uniform crisping. Without stirring, some pieces may stay sticky or baked unevenly, so it’s a key step to get that perfect crunchy texture throughout.
Can I store this toffee mix longer than a week?
For best taste and texture, enjoy it within a week at room temperature. If you need to keep it longer, freezing is the way to go and will maintain both flavor and crunch for up to three months.

Description
This Addicting Toffee Chex Mix is a crispy, caramel brittle snack combining crunchy Chex cereal and nuts coated in a buttery, sweet toffee glaze. Baked until perfectly crisp and broken into bite-sized shards, it’s an irresistible treat perfect for snacking or gifting.
Ingredients
Cereal & Nuts
- 8–9 cups Chex cereal (Rice Chex or mix of Rice & Corn)
- 1 1/2 cups nuts (pecan halves or walnuts)
Toffee Coating
- 1 cup unsalted butter (226 g / 2 sticks)
- 1 1/2 cups packed brown sugar (light or dark)
- 1/2 cup light corn syrup
- 1 tsp vanilla extract
- 1 tsp baking soda
- 1/2 tsp fine salt
Instructions
- Preheat & Set Up: Preheat your oven to 250°F (120°C). Line a large rimmed baking sheet or two with parchment paper. In a very large heatproof bowl, combine 8–9 cups of Chex cereal and 1 1/2 cups of nuts. Optionally warm the bowl under hot water and dry it to slightly warm it; this helps prevent the toffee from seizing later.
- Boil the Toffee: In a medium saucepan, melt together 1 cup unsalted butter, 1 1/2 cups packed brown sugar, and 1/2 cup light corn syrup over medium-high heat, stirring until smooth. Bring the mixture to a rolling boil, then let it boil without stirring for 5 minutes. Use a saucepan with high sides as the mixture will expand after adding baking soda.
- Create the Toffee Reaction: Remove the saucepan from heat and immediately whisk in 1 teaspoon vanilla extract, 1/2 teaspoon fine salt, and 1 teaspoon baking soda. The mixture will foam, lighten in color, and expand due to carbon dioxide bubbles, creating an airy and crisp brittle texture. Be cautious to avoid hot sugar burns.
- Coat the Mix (Work Quickly): Pour the foaming toffee syrup over the cereal and nuts. Using a silicone spatula, fold and toss quickly until every piece is glossy and fully coated. Scrape from the bottom and rotate the bowl to prevent any dry pockets.
- Bake the Addicting Toffee Chex Mix: Spread the coated cereal and nut mixture evenly on the prepared baking sheet(s). Bake in the preheated oven for 45–60 minutes, stirring every 15 minutes to redistribute the syrup and ensure even crisping. The mixture is done when pieces feel dry, light, and not tacky.
- Cool, Break & Store: Allow the Chex mix to cool completely on the pan for 30–45 minutes; it will harden as it cools. Once cooled, break into bite-sized shards. Store in an airtight container at room temperature for up to 1 week. For gifting, pack into cellophane bags and optionally sprinkle with flaky sea salt on top.
Notes
- Warming the mixing bowl before adding the toffee helps prevent the sugar mixture from seizing.
- Use a saucepan with high sides to accommodate expansion after baking soda is added.
- Stir the Chex mix every 15 minutes during baking to promote even coating and crispness.
- Be very careful during the addition of baking soda as the mixture will foam and can cause burns.
- Store the toffee Chex mix in an airtight container to maintain crispness for up to one week.
- Optionally sprinkle flaky sea salt on top before serving or gifting to enhance flavor contrast.
