Step 1

Any brand of toasted rice cereal will work here.

Step 2

Make foil sling for 8-inch square baking pan by folding 2 long sheets of aluminum foil so each is 8 inches wide. Lay sheets of foil in pan perpendicular to one another, with extra foil hanging over edges of pan. Push foil into corners and up sides of pan, smoothing foil flush to pan. Spray with vegetable oil spray.

Step 3

Melt butter in Dutch oven over low heat. Add marshmallows, vanilla, and salt and cook, stirring constantly, until melted and smooth, about 6 minutes. Off heat, stir in cereal, pretzels, peanuts, toffee bits, and chocolate chips until incorporated. Transfer mixture to prepared pan and press into even layer with greased spatula. Let treats cool for 15 minutes. Using foil overhang, remove treats from pan. Cut into 16 squares and serve.
