Ingredients You’ll Need
This Cornflake Chocolate Brittle Recipe is all about straightforward ingredients that each play an important role. The cornflakes bring crunch, the chocolate adds sweetness and richness, and the butter along with corn syrup create the sticky, shiny coating that holds everything together beautifully.
- 2 cups cornflakes: Provides the crispy base and light texture, crucial for that satisfying brittle crunch.
- 1 cup semisweet chocolate chips: Adds just the right amount of sweetness and creamy chocolate flavor to coat the brittle.
- 1/2 cup unsalted butter: Offers richness and helps the syrup bind the ingredients without overpowering the flavors.
- 1/2 cup light corn syrup: Key to creating the glossy, sticky syrup that holds the brittle together and gives it a smooth finish.
- 1 cup granulated sugar: Sweetens the syrup and caramelizes slightly for a deep, toasty flavor.
- 1/2 teaspoon vanilla extract: Adds a warm, fragrant hint to balance the sugars and chocolate.
- Pinch of salt: Enhances the overall flavor and cuts through the sweetness for perfect balance.
How to Make Cornflake Chocolate Brittle Recipe
Step 1: Prepare Your Baking Surface
Start by lining a baking sheet with parchment paper or a silicone baking mat. This step is crucial as it ensures the brittle won’t stick once it sets, making cleanup and removal a breeze.
Step 2: Make the Syrup
In a medium saucepan, melt the unsalted butter, light corn syrup, and granulated sugar over medium heat. Stir occasionally until the sugar fully dissolves and the mixture starts to simmer. This is the foundation of your brittle’s luscious coating.
Step 3: Boil for the Perfect Thickness
Let the syrup mixture come to a rolling boil, stirring constantly to avoid burning. Once boiling, stop stirring and allow it to cook for 3 minutes to thicken slightly—this will give your brittle that satisfying snap.
Step 4: Add Final Flavors to the Syrup
Remove the pan from the heat. Stir in the vanilla extract and a pinch of salt to brighten flavors and add depth to the sweet syrup.
Step 5: Combine Cornflakes and Syrup
Pour the cornflakes into a large mixing bowl. Immediately pour the hot syrup over the cornflakes and gently fold them together until every flake is thoroughly coated with that golden, glossy syrup.
Step 6: Melt the Chocolate
In a microwave-safe bowl or over a double boiler, melt your semisweet chocolate chips until smooth and silky. Patience here ensures the chocolate melts evenly without clumping.
Step 7: Mix Chocolate into Cornflake Mixture
Drizzle the melted chocolate over your syrup-coated cornflakes and gently fold until everything is evenly coated in a rich chocolate glaze—all of those textures marrying beautifully.
Step 8: Spread and Set
Transfer the chocolate-laden mixture to your prepared baking sheet. Press it down evenly to form a firm, flat layer. Then, pop it into the refrigerator for at least 30 minutes so it can harden just right.
Step 9: Break Into Pieces and Enjoy
Once fully set, break the brittle into rustic shards or bite-size chunks. This crunchy, chocolatey delight is now ready to be enjoyed!
How to Serve Cornflake Chocolate Brittle Recipe
Garnishes
For serving, consider sprinkling a light dusting of sea salt flakes on top for a burst of contrast, or even a sprinkle of crushed toasted nuts for added texture and a nutty aroma that complements the chocolate beautifully.
Side Dishes
This Cornflake Chocolate Brittle pairs wonderfully alongside a scoop of vanilla ice cream or a cup of rich coffee or tea. The sweet and crunchy brittle elevates any cozy snack time or dessert plate.
Creative Ways to Present
Try arranging the brittle shards in a decorative jar or cellophane gift bags tied with a ribbon to give as delightful homemade gifts. For a festive touch, layer the brittle pieces in a clear bowl for a striking centerpiece at parties or gatherings.
Make Ahead and Storage
Storing Leftovers
Store any leftover Cornflake Chocolate Brittle in an airtight container at room temperature for up to one week. Keeping it sealed prevents moisture from softening the crunch and keeps the chocolate from melting or blooming.
Freezing
If you want to keep your brittle longer, wrapping it tightly in plastic wrap and placing it in a freezer-safe bag allows freezing for up to three months. Just be sure to thaw it at room temperature before serving for the best texture.
Reheating
Since brittle is best enjoyed crunchy and cool, reheating is generally not recommended. However, if your chocolate has dulled or the brittle has softened too much, a quick chill in the fridge can restore some crispness.
FAQs
Can I use other types of cereal instead of cornflakes?
Absolutely! While cornflakes give that classic crunch and lightness, cereals like Rice Krispies or crispy oats can also work nicely, lending a different texture and flavor profile to the brittle.
Is this recipe gluten-free?
Cornflakes often contain gluten, so be sure to use certified gluten-free cornflakes if you need to make this treat gluten-free. The other ingredients are naturally gluten-free.
Can I substitute the butter with a dairy-free alternative?
Yes, you can use plant-based butter or margarine to make this recipe dairy-free. Just keep in mind that the flavor and texture might vary slightly, but it will still be delicious.
How long does the brittle keep its crunch?
Stored properly in an airtight container at room temperature, the Cornflake Chocolate Brittle Recipe stays crunchy for up to one week. Avoid humid conditions to prevent it from becoming sticky or soft.
Can I add nuts or dried fruits to this brittle?
Definitely! Toss in chopped nuts like almonds, pecans, or walnuts before spreading the brittle. Dried fruits like cranberries or raisins can also add a pleasant chewy contrast to the crisp, chocolatey brittle.
