Grease and set aside a 9”x13” cake pan.

In a large bowl, gently stir together cereal and cookies. Set aside.

Melt the butter in a large nonstick pan over medium heat. Add marshmallows and gently stir until completely melted. Remove from heat.

Pour the melted marshmallows over the cereal mixture, and gently stir to combine. Transfer to prepared baking pan and lightly press down the mixture into an even layer.

Spread melted white chocolate over the cereal. Garnish with chopped cookies and allow the chocolate and bars to set. Cut into bars and store in an airtight container at room temperature.
