1-Start: preheating your oven to 300°F and lining a baking sheet with parchment paper to keep things from sticking.

2-Melt the 4 tablespoons of room-temperature salted butter, ½ cup packed brown sugar, and ¼ cup light corn syrup together over medium heat until they’re fully combined, then bring the mixture to a boil and cook for 2 minutes before taking it off the heat.

3-Next, pour this warm sugar mixture over the 3 cups of cornflakes in a large heat-safe bowl and stir quickly to coat them evenly this step is crucial for that signature texture.

4-Spread the coated cornflakes onto your prepared baking sheet and pop it into the oven to bake for 30 minutes, watching to ensure it gets nice and crisp without burning.

5-After baking, let the brittle cool completely on the sheet before moving on.

6-Melting and Drizzling the Chocolate: For the finishing touch, melt the ½ cup of semisweet chocolate chips at 50% power in 30-second intervals in the microwave, stirring between each one until smooth. Drizzle this over the cooled brittle and let it set fully before breaking into pieces. This method ensures the chocolate adds just the right amount of richness without overwhelming the snack.
