Step 1

To a medium saucepan, add the chocolate chips, peanut butter, butter, and heat over medium-low heat to melt, stir very frequently until smooth and combined.

Step 2

Remove from the heat, add the vanilla salt, and stir to combine; set aside.

Step 3

To a very large bowl, add the Chex, 1 cup pretzels, pour the chocolate-peanut butter mixture over the top, and stir very well to combine.

Step 4

Add the confectioners’ sugar and stir to combine. At this point I recommend transferring everything into a jumbo (2.5-gallon) plastic storage bag. You can shake the sugar around easier, more effectively, and unless you have a ginormous bowl, it will become hard to accommodate the remaining ingredients.

Step 5

Add the remaining pretzels, M&M's, sprinkles, and shake or stir to combine. Serve immediately.
