Ingredients in Cornflake Chocolate Brittle
Here’s what you’ll need to make this addictive treat:
Cornflakes
The star of the show! The crunchy cornflakes form the base of this brittle, giving it that satisfying texture that everyone loves.
Chocolate Chips
A good quality chocolate is key to making this treat truly delicious. Semi-sweet chocolate chips work perfectly, but feel free to swap for milk chocolate or dark chocolate, depending on your taste.
Peanut Butter
Peanut butter adds a layer of richness and creaminess that takes this brittle from simple to extraordinary. It also helps bind the cornflakes and chocolate together.
Butter
Butter adds richness and helps to melt the chocolate and peanut butter together smoothly.
Vanilla Extract
A splash of vanilla enhances the flavor, bringing a little extra warmth and depth to this chocolatey treat.
(Note: the full ingredients list, including measurements, is provided in the recipe card directly below.)
Instructions
Ready to make the easiest and most satisfying dessert? Let’s get started:
Melt the Chocolate Mixture
In a medium saucepan, melt the butter, peanut butter, and chocolate chips together over low heat. Stir occasionally to ensure the mixture is smooth and fully combined. Once melted, remove from heat and stir in the vanilla extract.
Add the Cornflakes
In a large mixing bowl, add the cornflakes. Pour the melted chocolate mixture over the cornflakes and gently stir to coat them evenly. Be careful not to crush the cornflakes as you stir.
Shape the Brittle
Once all the cornflakes are coated, spread the mixture onto a baking sheet lined with parchment paper. Use a spatula to spread it out into an even layer. You can make it as thick or as thin as you like, depending on your preference for crunch.
Chill to Set
Place the baking sheet in the refrigerator and let the brittle chill for at least 30 minutes, or until the chocolate has fully set. The longer you chill, the firmer it will become.
Break into Pieces
Once set, break the brittle into bite-sized pieces. It will crack into perfect, uneven pieces, giving it that rustic “brittle” look.
Serve and Enjoy
Now it’s time to dig in! Serve immediately, or store in an airtight container at room temperature for up to a week.
