Cornflake Crack with Chocolate and Sea Salt Recipe
Introduction
Cornflake Crack is a delightful sweet and salty treat that combines crunchy cornflakes with buttery caramel and rich chocolate. This easy-to-make snack is perfect for anyone craving a satisfying homemade candy with a little crunch and a touch of indulgence.

Ingredients
- 1/2 cup salted butter
- 1/2 cup brown sugar (packed)
- 3 cups cornflakes cereal (NOT heaping)
- 12 ounces chocolate
- Maldon sea salt flakes (optional)
Instructions
- Step 1: Line a baking sheet with parchment paper or a silicone baking mat. Spread the cornflakes evenly in a single layer to ensure each flake can be coated well.
- Step 2: In a saucepan over medium heat, melt the butter and brown sugar together. Stir continuously until the mixture is smooth and starts to melt. Continue cooking and stirring for another 1-2 minutes.
- Step 3: Carefully pour the butter and sugar mixture over the cornflakes. Stir gently with a heat-resistant spatula to coat all the flakes evenly. Press the coated cornflakes into a rectangle shape on the baking sheet.
- Step 4: Bake in a preheated 350°F oven for 9-12 minutes. Check halfway through and use a spatula to press the edges back toward the center if they start to spread. Baking helps caramelize the mixture and set the toffee.
- Step 5: Let the tray cool completely after baking. The toffee will harden as it cools. Once set, break the mixture into pieces of your preferred size.
- Step 6: Melt the chocolate for dipping (see step 7). Dip half of each piece into the melted chocolate, then place on parchment paper to set. For an extra touch of flavor, sprinkle with Maldon sea salt flakes while the chocolate is still wet.
- Step 7: To melt the chocolate, put it in a microwave-safe bowl and microwave at 50% power in 30-second increments. Stir after each interval until the chocolate is completely melted and smooth.
Tips & Variations
- Use high-quality chocolate for dipping to improve flavor and texture.
- You can substitute cornflakes with other crispy cereals for a different crunch.
- For a nutty variation, sprinkle chopped toasted nuts over the chocolate before it sets.
- If you prefer less sweetness, reduce the brown sugar slightly or skip the chocolate dip.
Storage
Store Cornflake Crack in an airtight container at room temperature. It will keep fresh for up to one week. If dipped in chocolate, keep it in a cool, dry place to prevent melting. For longer storage, refrigerate and bring to room temperature before serving. Avoid storing in humid areas as the toffee can soften.

FAQs
Can I use unsalted butter instead of salted butter?
Yes, you can use unsalted butter. If you do, consider adding a pinch of salt to balance the sweetness and enhance the flavor.
What type of chocolate works best for dipping?
Semisweet or dark chocolate works well for dipping as they balance the sweetness of the toffee. Milk chocolate is also an option for a creamier, sweeter finish.

Cornflake Crack with Chocolate and Sea Salt Recipe
- Total Time: 25 minutes
- Yield: About 24 pieces 1x
Description
Cornflake Crack is a delightful sweet and salty treat featuring crunchy cornflakes coated in a buttery brown sugar toffee, baked to perfection, then dipped in melted chocolate and optionally sprinkled with sea salt flakes for an irresistible flavor contrast.
Ingredients
Toffee Mixture
- 1/2 cup Salted Butter
- 1/2 cup Brown Sugar (packed)
- 3 cups Cornflakes Cereal (not heaping)
Chocolate Coating
- 12 ounces Chocolate (for melting and dipping)
Optional Topping
- Maldon Sea Salt Flakes
Instructions
- Prepare Cornflakes Base: Line a baking sheet with parchment paper or a silicone baking mat. Spread the cornflakes evenly on the sheet in a single layer to ensure even coating by the toffee.
- Make Toffee Mixture: In a saucepan over medium heat, melt the salted butter with the packed brown sugar, stirring continuously. Once the mixture is smooth and fully melted, continue cooking for 1-2 minutes while stirring frequently to help it thicken slightly.
- Coat Cornflakes: Carefully pour the hot butter-sugar mixture over the cornflakes on the baking sheet. Gently stir with a heat-resistant spatula to coat all the cornflakes evenly. Then shape the mixture into a rectangle, pressing the cornflakes together firmly.
- Bake the Mixture: Preheat the oven to 350°F (175°C). Bake the coated cornflakes mixture for 9-12 minutes. Check halfway through baking and use a spatula to press the edges towards the center if needed. Baking caramelizes and sets the toffee.
- Cool and Break: Remove from oven and allow the baking sheet to cool completely. The mixture will harden as it cools. Once fully set, break the toffee into pieces of your desired size.
- Melt the Chocolate: Place the chocolate in a microwave-safe bowl. Microwave at 50% power in 30-second increments, stirring after each, until smooth and fully melted.
- Dip Pieces in Chocolate: Dip half of each cornflake crack piece into the melted chocolate, then place on parchment paper to set.
- Optional Salt Sprinkle: For an extra salty-sweet flavor, sprinkle Maldon sea salt flakes over the chocolate-coated side before it hardens.
Notes
- Make sure to spread the cornflakes in a single layer to achieve even toffee coating.
- Stir the toffee mixture constantly while melting to prevent burning.
- Baking sets the toffee and develops a richer caramel flavor.
- Use a heat-resistant spatula to handle the sticky cornflake mixture safely.
- Chocolate melting can also be done using a double boiler as an alternative to the microwave.
- Store cornflake crack in an airtight container to keep it crisp and fresh.
