Toffee Chex Mix delivers the kind of caramelized crunch that disappears in seconds once a bowl hits the table. This is my go-to when I need a quick sweet snack for family movie nights or a holiday party treat that feels special but requires almost no planning. Toffee Chex Mix brings together basic pantry staples and a little butter magic for an utterly craveable result.
Every time I make a batch for the neighborhood bake sale it disappears before any other treat.
Gather Your Ingredients
- Chex cereal: About four cups. Any variety rice corn or wheat Chex. Pick the freshest box for maximum crunch.
- Unsalted butter: Half a cup. This forms the buttery toffee. Make sure it is good quality for best flavor.
- Brown sugar: One cup. Gives that deep caramel taste. Look for soft moist brown sugar.
- Vanilla extract: One teaspoon. For a sweet aroma. Choose pure vanilla if you can.
- Salt: Half a teaspoon. Balances the sweetness and brings out aroma. Use flaky sea salt for a little extra crunch.
- Chopped nuts (optional): One cup. Adds extra richness and texture. Pecans or almonds are always a hit. Make sure nuts are fresh to avoid any bitterness.
How to Make It
- Prepare the Baking Sheet:
- Line a large baking sheet with parchment paper so your mix will not stick and is easier to clean up.
- Melt Butter and Make Toffee:
- Place butter in a medium saucepan over low heat. Melt fully then stir in the brown sugar. Continue mixing until the mixture is bubbly and combined which takes three to five minutes. The sugar should dissolve and the mix should look smooth and shiny. The key is patience and stirring frequently.
- Add Flavorings:
- Once bubbly remove the pan from heat. Stir in the vanilla and salt. Be careful vanilla may sizzle as you add it. Quickly mix in so the flavor infuses the toffee.
- Coat the Cereal:
- Pour Chex cereal into a large bowl. Drizzle the hot toffee mixture over the cereal. Using a silicone spatula gently toss and fold so each piece is evenly coated. Try not to crush the cereal.
- Bake for Crunch:
- Spread the coated cereal in a single layer on the prepared baking sheet. Bake in the oven at three hundred fifty degrees for about fifteen minutes. Stir gently halfway through to prevent clumps and make sure every piece crisps up.
- Cool Completely:
- Allow the mix to cool fully on the baking sheet at room temperature before breaking apart and serving. This sets the toffee so it is nice and crunchy.

My favorite part about making this recipe is stirring the warm toffee over the cereal. That sweet aroma drifts through the kitchen and reminds me of lazy winter afternoons with my family. Everyone would gather waiting for it to cool just enough before diving in for a first bite still warm and gooey.
Flavor Boosters
Let Toffee Chex Mix cool completely before storing. Always use an airtight container so moisture does not sneak in and turn it soggy. This snack stays perfectly crisp for up to two weeks at room temperature. If the weather is especially warm or humid tuck it in the fridge to keep it fresh a little longer.
Serving Suggestions
I love pouring this into paper cones for easy snacking at parties. For holidays sprinkle in colored candies or drizzle with cooled melted chocolate. To make it even more festive sprinkle sea salt or crushed peppermint on top while still warm.
Creative Twists
Add warm spice like cinnamon or pumpkin pie spice in fall. For winter mix in dried cranberries or white chocolate. For summer add some toasted coconut. It is easy to create new versions all year.

If you add chocolate or candies wait until the mix is cool to avoid melting. Toffee Chex Mix freezes better than you might think. Spread cooled mix in a freezer bag, remove as much air as possible, then freeze for up to two months. Let it thaw uncovered so it snaps back to crispy perfection.
