Preheat oven to 375℉. Line a large baking sheet with parchment paper.
To the pan, add Bugles, cereal, puff corn and pretzels, set aside.
In a medium saucepan, combine brown sugar, butter and corn syrup. Cook over medium heat, stirring occasionally, until mixture comes to a full boil. Remove from heat and stir in vanilla and baking soda.
Pour the syrup over the Bugle mixture and using two wooden spoons, toss to coat all of the pieces well.
Bake for 12 to15 minutes, stirring every 4 to 5 minutes. Watch very closely, it can burn fast!
