In a large saucepan over medium heat, melt the butter.
Stir in the marshmallows and stir occasionally until fully melted.
Stir in the peanut butter until fully incorporated.
Remove from the heat and stir in the vanilla, and the cornflake cereal.
Press the mixture evenly into a 9 x 13 pan, and allow it to completely cool.
Once cooled, cut the tiger paws into squares and place them on a parchment-lined baking sheet.
Place the chocolate chips in a microwave-safe bowl and microwave on medium-low power at 30-second intervals (stirring after each interval) until completely melted and smooth.
Drizzle the melted chocolate over the tiger paws cereal bars and allow the chocolate to set and harden.
Serve and enjoy!
