Ingredients Needed for Cornflake Candy
Here’s a quick look at the 7 simple ingredients you’ll need to make this easy cornflake recipe. This corn flakes candy is perfect for the holidays! See the printable recipe card below for exact amounts.

- Cornflakes: The base of this cornflake brittle, giving it that perfect crunchy texture. Any brand works! I usually grab store brand since it’s cheaper. Frosted Flakes work too, but they’ll make the brittle a little sweeter.
- Butter: I prefer salted butter for that sweet and salty flavor. If using unsalted butter, simply add a pinch of salt.
- Brown Sugar: Light brown sugar combines with the butter to make the sweet caramel coating.
- Almond Bark: I use chocolate almond bark, but chocolate chips work too if you can’t find it at your grocery store.
- Candy Melts: Red and green candy melts add those festive Christmas colors. Feel free to change the colors for other holidays!
- Sprinkles: Optional, but red, green, or Christmas sprinkles are a fun way to dress up this holiday candy.
How to make Christmas Cornflake Brittle

Step 1. Preheat the oven to 350°F. Line a baking sheet or jelly roll pan with parchment paper and set aside. Place the cornflakes in a large mixing bowl. In a medium saucepan over medium heat, add the butter and brown sugar. Cook for about 2 minutes, until the butter melts and the mixture comes to a boil. Let bubble for another 1-2 minutes.

Step 2. Immediately pour the butter and brown sugar mixture over the cornflakes. Stir until all the cornflakes are evenly coated.

Step 3. Spread the coated cornflakes evenly onto the prepared baking sheet. Bake in the preheated oven for 12-15 minutes, or until just golden brown.

Step 4. In a microwave-safe bowl, melt the chocolate almond bark in 30-second intervals, stirring between each, until smooth. Spread the melted chocolate evenly over the brittle.

Step 5. In a separate microwave-safe bowl, melt the red candy melts in 30-second intervals, stirring between each, until smooth. Repeat with the green candy melts in another bowl.

Step 6. Drizzle the melted red and green candy melts over the brittle and gently swirl with a knife. Top with Christmas sprinkles if desired. Let cool completely, then break into pieces and serve!
Cornflake Brittle Tips and Tricks
Here are some simple tips to ensure success each and every time!
- Baking Sheet Size: Any size baking sheet works! Just remember, the bigger the pan, the thinner your corn flake candy will be. We use different sizes depending on what we have on hand. For thicker brittle, use a smaller baking sheet. For thinner pieces, use a larger one.
- Don’t Overcook the Caramel: Keep an eye on the butter and brown sugar mixture as it bubbles. Follow the cooking times in the recipe to avoid burning the caramel.
- Chocolate Options: Feel free to change up the chocolate! Almond bark is my favorite since it isn’t too sweet, but white chocolate chips, milk chocolate chips, or dark chocolate work great too. If you love that sweet and salty combination, try my Salted Caramel Pretzel Bark too!
- Candy Melts: These can be omitted or changed to different colors to fit any holiday or occasion. The cornflake brittle is still delicious without the extra drizzle! For another festive chocolate treat, try my Oreo Peppermint Bark.
- Optional Toppings: Chopped nuts or a sprinkle of flaky sea salt are great additions for extra crunch and a sweet and salty finish.
Storing Leftover Christmas Cornflake Brittle
If you’re lucky enough to have leftover cornflake crack brittle, here are some simple tips to keep it fresh!
- Room Temperature: Store in an airtight container for up to 2 weeks. I don’t recommend refrigerating it since the brittle tends to get soft.
- Freezer: Once completely cooled, place in a freezer-safe container for up to 3 months. When ready to enjoy, let it thaw at room temperature for at least one hour.

Cornflake Brittle Recipe FAQs
A little chewiness is normal from the caramel coating, but the cornflakes should still have plenty of crunch. If yours is too soft, the caramel may not have cooked long enough, or the brittle may need more time to set completely before breaking it into pieces.
Nope! You don’t need a candy thermometer for this recipe. Just follow the stovetop cooking times and watch for the butter and brown sugar mixture to come to a gentle boil before coating the cornflakes.
