Line an 8-inch square baking dish with parchment paper, leaving a slight overhang.
In a microwave-safe bowl, melt chocolate wafers according to package directions, until completely melted. Set aside.
Place butter, marshmallows, almond butter, and salt in a large pot. Stir to combine and melt over medium heat, stirring frequently.
Take pot off the heat and pour in the Cocoa Krispies; mix thoroughly to combine.
Working quickly before the cereal isn't pliable anymore and chocolate hardens, put a little cooking spray on a wooden spoon and press half of cereal mixture into the baking dish. Spread half of the melted chocolate on top. Repeat with remaining cereal and chocolate.
Let chocolate harden and set, then cut into squares and enjoy!
Notes
You can swap out the white chocolate for regular chocolate, and the almond butter for peanut butter.
