How to Make Cornflake Chocolate Brittle

Preheat the oven: Set your oven to 300°F (150°C). Line a 9×13 baking sheet with parchment paper, ensuring it’s ready for your delicious creations.
-
Prepare cornflakes: Pour 3 cups of cornflakes into a large heat-safe bowl. Make sure they are broken pieces for the best texture and crunch.

Melt the ingredients: In a medium saucepan over medium heat, combine 4 tablespoons of salted butter, 1/2 cup of packed brown sugar, 2 tablespoons of light corn syrup, and 1 teaspoon vanilla. Stir occasionally while the butter melts.

Cook the caramel: Stir for 1-2 minutes until the butter has melted, then bring the mixture to a gentle boil. Lower the heat and cook for another 1-2 minutes until it’s smooth and glossy.

Combine with cornflakes: Carefully remove the caramel mixture from the heat and pour it over the cornflakes. Stir gently to coat each flake evenly, ensuring no spot is left untouched.

-
Cool completely: Once baked, remove from the oven and allow the brittle to cool completely on the baking sheet. The cooling will allow it to firm up nicely.

Cornflake Chocolate Brittle Recipe FAQs
What type of cornflakes should I use for the Cornflake Chocolate Brittle?
Use regular cornflakes for the best flavor and crunch. Stay away from those flavored or frosted varieties, as they won’t deliver the same delightful texture and sweetness in your brittle.
How should I store Cornflake Chocolate Brittle?
Store your Cornflake Chocolate Brittle in an airtight container at room temperature for up to 1 week. If you prefer a longer shelf life, you can keep it in the fridge, where it will stay fresh for up to 2 weeks. Just remember to wrap it well to avoid moisture!
Can I freeze Cornflake Chocolate Brittle?
Absolutely! For long-term storage, freeze the brittle in a freezer-safe container for up to 2 months. Just make sure to layer it with parchment paper to prevent the pieces from sticking together. When you’re ready to indulge, simply thaw it at room temperature for a few hours!
How can I troubleshoot if my caramel mixture isn’t coming together?
If your caramel isn’t coming together as planned, ensure you’re stirring consistently while cooking and maintaining a gentle boil. If it’s too grainy, you may be cooking it too high; lower the heat and continue stirring until it becomes smooth. If it hardens too much before coating the cornflakes, you can gently reheat it on the stovetop with a splash of water to bring it back to a pourable state.
Are there any dietary considerations with Cornflake Chocolate Brittle?
Yes, if you or your guests have allergies, be cautious with this recipe. The brittle contains butter (which has dairy), and chocolate chips (which may have traces of allergens). Always check product labels for potential cross-contamination if cooking for someone with food sensitivities. If you’re considering it for pets, remember that chocolate can be toxic to dogs and cats, so keep this treat safely out of reach!
Can I make substitutions in the recipe?
Very! Feel free to add in nuts like pecans or almonds for a delightful crunch, or swap the semisweet chocolate with white chocolate for a different flavor. Just keep in mind that the overall taste and texture may vary slightly, but that’s part of the fun of making it your own!
