This crunchy cornflake delight turns everyday ingredients into an addictive snack that's both toffee-like and bark-inspired. The real magic kicks in when butter and brown sugar turn into caramel around the cornflakes, making a crunchy, brittle treat that gets even better with a chocolate coating.
I whipped up this cornflake treat for a neighborhood get-together at the last minute and came home with nothing but an empty dish and folks asking me how to make it. It's become my favorite quick fix when I want to wow people without spending hours in the kitchen.
What You'll Need
- Salted Butter: Forms the rich foundation for your toffee grab some European-style for extra flavor depth
- Brown Sugar: Adds those deep caramel notes you can't get from white sugar try dark brown for even stronger flavor
- Cornflakes Cereal: Gives you that awesome crunch factor plain versions work better so it's not too sweet
- Chocolate: Not required but definitely worth adding pick good quality for the best taste
- Maldon Sea Salt Flakes: The finishing touch that makes the sweet-salty combo pop
Easy Preparation Steps
- Set Up Your Base:
- Lay cornflakes flat on a baking sheet lined with parchment. This helps them get evenly coated and stops them from sticking together when you pour the hot toffee mix. Try not to break the flakes since you want them nice and crispy.
- Make Your Toffee Mix:
- Mix butter and brown sugar in a pot over medium heat, stirring for about 5 minutes. You'll know it's done when everything looks smooth and bubbles form around the edges. This step turns ordinary cornflakes into something amazing.
- Mix Everything Together:
- Drizzle the hot toffee over your cornflakes and fold gently until they're all covered. Work fast but careful so you cover everything without breaking too many flakes. You want them shiny and coated without turning to mush.
- Pop In The Oven:
- Bake at 350°F for 9-12 minutes, keeping an eye on it so it doesn't burn. This step is super important because it lets the caramel turn into real toffee, which gives this treat its amazing flavor and that snap when you bite it.
- Let It Harden:
- Wait until everything cools completely and gets hard. Your patience will pay off with pieces that break with a snap instead of bending. Break it into random chunks for that homemade look.
- Add Chocolate:
- Melt your chocolate slowly and dip each piece halfway, letting extra chocolate drip off. Put them on parchment and sprinkle with sea salt while the chocolate's still wet. The mix of smooth chocolate and crunchy toffee makes an amazing combo.

This crunchy treat always reminds me of my grandma's butter crunch that showed up every Christmas. The first time I brought it to a family party, my uncle was convinced I'd bought it from a fancy candy shop. I felt so proud when I told him I made it myself, and that's why I keep making this time and again.
Getting That Perfect Crunch
Getting the texture just right comes down to how much caramel coats each cornflake. Too many cornflakes will leave you with dry, barely sweet pieces, while too few makes it overly sweet and hard to bite. Stick to the recipe's advice about not using too many cornflakes, and maybe even use a bit less than called for. This way, every piece gets plenty of that buttery caramel goodness.
Saving For Later
This snack actually gets better after a day or two as the flavors come together and the texture sets just right. You can make it up to five days before you need it and keep it in a sealed container with parchment between layers so pieces don't stick together. If you want to keep it longer, pop it in the fridge for up to two weeks. The chocolate layer actually helps keep it fresh longer.

Tasty Twists
The basic version tastes amazing, but you can always play around with it. Try some white chocolate drizzled on top for a nice look, or mix in 1/2 cup of toasted coconut before baking for a tropical feel. During fall, add 1/4 teaspoon of cinnamon or pumpkin spice to the caramel mix. If you love dark chocolate, try sprinkling some espresso powder on the melted chocolate before it hardens.
