How to Make Addicting Toffee Chex Mix (Crispy Caramel Brittle)
Step 1: 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 your Chex cereal and nuts. A little tip: warming the bowl under hot water before drying it helps keep the toffee from seizing up later on!
Step 2: Boil the Toffee
In a medium saucepan, melt your unsalted butter with brown sugar and corn syrup over medium-high heat while stirring until smooth. Once melted, bring it to a rolling boil and let it bubble away without stirring for about five minutes. This step is crucial as it creates that delicious caramel base!
Step 3: Create the Toffee Reaction
Remove the saucepan from heat once your timer goes off. Quickly whisk in vanilla extract, fine salt, and baking soda. Be careful as the mixture will foam and expand—this reaction creates those lovely micro-bubbles that give our brittle its airy crunch.
Step 4: Coat the Mix (Work Quickly)
Now comes the fun part! Pour that foaming toffee over your cereal and nuts. Use a silicone spatula to fold and toss quickly until every piece is glossy and coated. Remember to scrape from the bottom of the bowl so nothing gets left behind.
Step 5: Bake the Addicting Toffee Chex Mix
Spread your coated mix onto the prepared baking sheets in an even layer. Bake in your preheated oven for about 45–60 minutes, stirring every 15 minutes. You’ll know it’s done when pieces feel dry and light—not tacky at all!
Step 6: Cool, Break & Store
Let your delectable creation cool completely on the pan—about 30–45 minutes should do it! As it cools, it’ll harden beautifully. Once cooled, break into bite-sized shards and store them airtight at room temperature for up to one week. If you’re feeling generous, pack them into cellophane bags with a sprinkle of flaky salt on top—a perfect little gift!
Pro Tips for Making Addicting Toffee Chex Mix (Crispy Caramel Brittle)
Making this toffee Chex mix is straightforward, but a few tips can elevate your results and ensure it’s as addicting as promised!
- Use Fresh Ingredients: Fresh nuts and cereal make a noticeable difference in flavor and texture. Stale ingredients can lead to a less crispy and flavorful mix.
- Watch the Boil: Keep an eye on the toffee as it boils. Timing is crucial—boil for exactly five minutes to achieve that perfect caramelization without burning.
- Work Quickly: Once the toffee is ready, pour it over the Chex and nuts immediately. The toffee thickens quickly, so swift folding is essential for even coating.
- Check for Crispness: When baking, use the dry and light test. If pieces feel tacky, they need more time in the oven. Properly baked Chex mix will have a delightful crunch.
- Cool Completely: Allow the mix to cool fully before breaking it apart. This ensures that each piece sets properly and maintains its crispy texture.
