  • Total Time: 35 minutes
  • Yield: 6 servings

Ingredients

Ingredients

  • 3 cups cornflakes
  • 4 tablespoons salted butter, room temperature
  • 1/2 cup packed brown sugar
  • 2 tablespoons light corn syrup
  • 1 teaspoon vanilla bean paste
  • 1/2 cup semisweet chocolate chips, for drizzle
  • Flakey sea salt, for sprinkling

Instructions

  1. Preheat Oven: Preheat the oven to 300 degrees F (150 degrees C). Line a 9×13 inch baking sheet with parchment paper and set it aside to prepare for baking the brittle.
  2. Prepare Cornflakes: Pour 3 cups of cornflakes into a large heat-safe mixing bowl, ensuring they are ready to be combined with the caramel.
  3. Make Caramel Mixture: In a medium saucepan over medium heat, combine 4 tablespoons of salted butter, 1/2 cup packed brown sugar, 2 tablespoons light corn syrup, and 1 teaspoon vanilla bean paste. Stir continuously to melt the butter and dissolve the sugar evenly.
  4. Cook Caramel: Stir for 1-2 minutes until the butter is melted, then bring the mixture to a gentle boil. Once boiling, reduce heat to low and continue to cook while stirring for another 1-2 minutes until the caramel is smooth, glossy, and slightly thickened.
  5. Combine Caramel and Cornflakes: Remove the caramel from heat and immediately pour it over the cornflakes in the bowl. Toss gently but thoroughly to ensure all the cornflakes are evenly coated with the caramel.
  6. Spread on Baking Sheet: Transfer the coated cornflakes onto the parchment-lined baking sheet. Spread them out evenly into a 1/2 to 3/4-inch thick layer to ensure uniform caramelization during baking.
  7. Bake the Brittle: Bake in the preheated oven for 20 to 30 minutes until the brittle is golden brown and caramelized. Watch closely toward the end of baking to prevent burning.
  8. Cool the Brittle: Remove the baking sheet from the oven and let the brittle cool completely on a wire rack or at room temperature to harden.
  9. Drizzle Chocolate: Melt 1/2 cup semisweet chocolate chips in a microwave or double boiler until smooth. Drizzle generously over the cooled brittle, then sprinkle with flakey sea salt for contrast.
  10. Set and Serve: Allow the chocolate drizzle to set completely at room temperature or in the refrigerator. Once set, break the brittle into pieces and serve.

Notes

  • Monitor the brittle closely while baking to avoid burning as caramel can darken quickly.
  • Use flakey sea salt for a delicate crunchy texture and balanced salty flavor.
  • Make sure the brittle is completely cooled before drizzling chocolate to prevent melting and running.
  • Store any leftovers in an airtight container to maintain crispness.
  • Vanilla bean paste adds a richer flavor than vanilla extract, but the latter can be substituted if necessary.
