Line 2 large rimmed pans with waxed paper. In large bowl, add cereal.
In medium microwavable bowl, microwave 2 cups of the baking chips uncovered on High 45 to 60 seconds, stirring after 45 seconds, until chips are starting to melt. Continue heating in 15-second increments, until chips are melted and smooth. Pour over cereal; mix to thoroughly coat. Spread mixture in one of the pans; top with sprinkles. Cool 20 to 30 minutes or until set.

Meanwhile, spread cookies and pretzels in single layer, right side up, in remaining pan. In same microwavable bowl, microwave remaining 1/2 cup baking chips uncovered on High 30 to 60 seconds, stirring after 30 seconds, until chips are melted and smooth. Transfer melted chips to small resealable food-storage plastic bag, and cut small corner off one end of bag. Drizzle onto cookies and pretzels; sprinkle with nonpareils. Cool 20 to 30 minutes or until set.

(I drizzled with a spoon.)

Break cereal mixture into bite-size pieces; transfer to large serving bowl. Carefully break apart pretzels and cookies, if necessary. Add to bowl; stir in candies.

Notes- I used mini marshmallows instead of nuts, I didn’t have any nuts or did I have any holiday sprinkles I just used what I had what was rainbow sprinkles. I used half the bad of white chips for the Cereal and the other half for the pretzels and wafers. Make as little or a big batch.This made 4 quarts as you can see in my bowl we did eat some and I bagged some up before I took the picture. This made a lot. Enjoy 😉
