Prepare a 8×8 or 9×13 inch baking dish with non-stick cooking spray topped with layers of parchment paper that hang over the sides.

Pour the cereal into a large bowl for mixing.

Melt the butter in a large sauce pan over low heat and stir in the peanut butter until combined. Add the marshmallows and stir until they’ve melted into the peanut butter mixture. Remove from the heat and pour over the krispie cereal.

Grease your hands with butter or non-stick spray and mix the krispie mix with a spoon and/or your hands until fully incorporated. Press into the baking dish until it’s flat. Set aside to cool.

Pour the chocolate chips into a glass dish and microwave for 30 seconds then stir. Repeat 3-4 times, stirring after each time you heat until the chocolate has melted and is smooth.

Spread the layer of melted chocolate over the top of the cooled krispies. Sprinkle with flaky salt.

Cool or chill until firm. Slice and enjoy!
