Prepare your workspace by lining a baking sheet with parchment paper.

In a large mixing bowl, pour in the Honeycomb cereal.

In a medium saucepan, combine the light brown sugar, unsalted butter, and light corn syrup over medium heat.

Once thickened, stir in the vanilla extract and baking soda.

Pour the warm caramel over the cereal and toss gently to coat.

Combine sugar and cinnamon in a small bowl, then sprinkle over the caramel-coated cereal.

Spread the mixture onto the prepared baking sheet and let cool for 30 minutes.

Once cooled, break into pieces and store in an airtight container.
