Line a baking sheet with foil or parchment paper, set aside.
Pour the cereal into a large bowl, set aside.
In a microwave-safe bowl add in chocolate chips, almond butter, and butter and microwave in 30-second intervals, stirring after each interval, until completely melted and smooth.
Whisk in vanilla and salt.
Pour the melted chocolate mixture over the cereal, gently folding the mixture to completely coat the cereal.
If you have a large zip top bag, add the cereal and half of the powdered sugar into the bag, shaking to combine. Add in the remaining powdered sugar and repeat the process. If you don’t have a large zip top bag, sift half of the powdered sugar over the top of the cereal, stirring to coat. Sift the remaining powdered sugar and gently combine.
Once coated, spread cereal mixture out onto the prepared baking sheet and refrigerate until firm, about 60 to 90 minutes.
When transferring to a plastic storage container or serving bowl, fold in chocolate coated almonds and brownies pieces.
Serve immediately or store in an airtight container in the fridge and freezer.
