My buddy, V, told me about this recipe years ago.  Neither of us have made it,  but it’s on both of our “to do" lists.

Makes 9 servings

9 tablespoons unsalted butter
1 teaspoon salt
12 cups (2 1/2 bags) miniature marshmallows
6 cups Rice Krispies cereal
6 cups Cap'n Crunch cereal
6 cups Froot Loops cereal
Vegetable-oil cooking spray

Directions

Lightly spray a 9-by-9-by-2-inch baking pan with vegetable-oil cooking  spray; set aside. Melt butter in a large pot over medium heat. Add salt and  marshmallows; stir with a wooden spoon until melted. Remove from heat. Add Rice  Krispies, Cap'n Crunch, and Froot Loops, and stir until combined.

Transfer the mixture to the prepared pan. To prevent sticking, coat your  hands with vegetable spray, and press the mixture evenly into the pan. Let cool,  about 30 minutes.

Cut into 3-by-3-inch bars. Store in an airtight container for up to 3 days.
