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 with parchment paper. In a very large heatproof bowl, combine 8–9 cups of Chex cereal with 1 1/2 cups of nuts. It helps to warm your bowl slightly under hot water before drying it. This little trick keeps your toffee from seizing up later!
Step 2: Boil the Toffee
In a medium saucepan over medium-high heat, melt together the butter, brown sugar, and corn syrup until smooth. Once it reaches a rolling boil, set your timer and let it boil without stirring for exactly five minutes. Remember—a high-sided saucepan works best here since the mixture will expand when you add baking soda!
Step 3: Create the Toffee Reaction
Remove your saucepan from heat and whisk in vanilla extract, fine salt, and baking soda immediately. Watch as the syrup foams up and lightens in color! This reaction creates those delightful micro-bubbles that make our brittle so airy and crisp. Just remember—hot sugar can burn, so keep hands clear!
Step 4: Coat the Mix (Work Quickly)
Pour that foaming golden goodness over your cereal and nut mixture. Using a silicone spatula, fold and toss quickly until every piece is coated in that glossy caramel. Be sure to scrape from the bottom of your bowl so nothing gets left dry!
Step 5: Bake the Addicting Toffee Chex Mix
Spread your coated mixture evenly onto prepared baking sheets. Pop them into your preheated oven and bake for about 45–60 minutes. Make sure you stir every 15 minutes—this helps redistribute that syrupy goodness so everything crisps up perfectly! You’ll know it’s done when pieces feel dry and light.
Step 6: Cool, Break & Store
Let your delicious creation cool completely on the pan for about 30–45 minutes; it’ll firm up as it cools down. Once cooled, break into bite-sized pieces and store in an airtight container at room temperature for up to one week. Want to gift some? Pack them into cellophane bags with a sprinkle of flaky salt on top for that fancy touch!
Enjoy every crunchy-sweet bite—you might find yourself coming back for more!
Pro Tips for Making Addicting Toffee Chex Mix (Crispy Caramel Brittle)
Making the perfect Addicting Toffee Chex Mix is easy with a few helpful tips to ensure your treat turns out irresistibly crunchy and delicious!
-
Use fresh ingredients: Fresh nuts and cereals can significantly enhance the flavor and texture of your mix. Stale ingredients lead to a less satisfying crunch, so be sure to check their freshness before using them.
-
Work quickly when coating: The toffee cools down rapidly, which makes it essential to coat the cereal and nuts as soon as you pour it over. This ensures an even distribution of that scrumptious caramel flavor throughout your mix.
-
Choose the right baking sheet: A large rimmed baking sheet allows for even heat distribution while baking. If you don’t have one, using two smaller sheets will work just fine but make sure they are both well lined with parchment paper.
-
Stir regularly while baking: Stirring every 15 minutes helps prevent burning and ensures that each piece gets beautifully crisped. It also redistributes any syrup that may settle at the bottom, giving you a consistent texture.
-
Let it cool completely before breaking: Patience is key! Allowing your mix to cool fully on the pan lets it harden properly, resulting in those delightful shatteringly crispy shards that everyone loves.
