In large saucepan melt butter over low heat. Add the zest of 1 lemon. Add marshmallows and stir until completely melted. Remove from heat. Add KELLOGG'S RICE KRISPIES cereal. Stir until well coated. Using buttered spatula evenly press mixture into 9 x 9 x 2-inch pan coated with cooking spray. Let cool completely. Cut lemon Rice Krispies Treats to desired portions. (We like 2" squares!) In a double boiler, melt white baking chocolate. Spread white chocolate on top of each pre-cut lemon Rice Krispies Treat. Let chocolate cool until hardened. Enjoy!
