Crunchy Cornflake Toffee Delight

This homemade cornflake crack transforms simple ingredients into an irresistibly crunchy, sweet treat that's part toffee, part candy bark. The magic happens when butter and brown sugar caramelize around cornflakes, creating a brittle-like confection that's elevated with a dip in chocolate.

I first made this cornflake crack for a last-minute neighborhood potluck and returned home with an empty plate and requests for the recipe. The simplicity makes it my go-to when I need something impressive without the fuss.

Ingredients

• Salted Butter: Creates the rich caramel base for your toffee look for European-style butter for extra richness
• Brown Sugar: Provides deep molasses notes that plain sugar cannot match use dark brown for intensified flavor
• Cornflakes Cereal: Delivers the perfect crunch and texture unsweetened varieties work best to balance the sweetness
• Chocolate: Optional but highly recommended choose high-quality chocolate for the best flavor
• Maldon Sea Salt Flakes: A finishing touch that elevates the sweet-salty combination

Step-by-Step Instructions

Prepare the Base:

Spread cornflakes in a single layer on a parchment-lined baking sheet. This ensures even coating and prevents clumping when you add the hot toffee mixture. Take care not to crush the cereal as you want those crisp edges intact.

Create the Caramel:

Combine butter and brown sugar in a saucepan over medium heat, stirring continuously for about 5 minutes. You'll know it's ready when the mixture becomes completely smooth and bubbles around the edges. This step creates the caramel that transforms ordinary cornflakes into something magical.

Coat the Cornflakes:

Pour the hot caramel over the cornflakes and gently fold until every piece is coated. Work quickly but carefully to ensure even coverage without breaking the flakes. The goal is glossy, caramel-coated pieces with minimal broken bits.

Bake to Set:

Place in a 350°F oven for 9-12 minutes, watching carefully to prevent burning. This crucial step allows the caramel to transform into toffee, intensifying the flavor and creating that signature crackly texture that gives this treat its name.

Cool and Break:

Allow the mixture to cool completely until hard and set. This patience pays off with perfectly crisp pieces that snap rather than bend. Break into irregular pieces for that homemade rustic appeal.

Chocolate Dip:

Melt chocolate slowly and dip each piece halfway, allowing excess to drip off. Place on parchment paper and sprinkle with sea salt flakes while still wet. The contrast between the rich chocolate and crunchy toffee creates an irresistible texture combination.

Pin it

This cornflake crack reminds me of the butter crunch candy my grandmother made every Christmas. The first time I served it at a family gathering, my uncle insisted it must have come from a specialty confectionery. That moment of pride when I revealed I made it myself inspired me to keep this recipe in regular rotation.

Perfecting the Texture

The key to achieving the perfect texture lies in the cornflake-to-caramel ratio. Too many cornflakes will result in dry, barely coated pieces, while too few will create an overly sweet, hard-to-eat candy. Follow the recipe's guidance about not using heaping cups of cereal, and if anything, use slightly less than the called-for amount. This ensures every piece receives a generous coating of the buttery caramel mixture.

Make-Ahead and Storage

Cornflake crack actually improves with a bit of time, as the flavors meld and the texture sets perfectly. You can make this up to five days ahead and store in an airtight container with parchment paper between layers to prevent sticking. For longer storage, keep in the refrigerator for up to two weeks. The chocolate coating acts as a protective layer that helps preserve freshness.

Flavor Variations

While the classic version is perfect on its own, this recipe welcomes creative adaptations. Try drizzling with white chocolate for visual contrast, or mix in 1/2 cup of toasted coconut before baking for tropical notes. For a seasonal twist, add 1/4 teaspoon of cinnamon or pumpkin pie spice to the caramel mixture. Dark chocolate lovers might appreciate a sprinkle of espresso powder on the melted chocolate before it sets.
