Key Lime Pie Rice Krispie Treats

Since we are all anxiously waiting for spring to arrive, I thought I would share a fun new treat. If you like Key Lime Pie, I think you are going to love these treats! They are mildly sweet, tart and tangy, and chewy just like all rice krispie treats should be. Did I mention they are drizzled with white chocolate and sprinkled with graham cracker crumbs? Total yum! And they are green so if you are looking for something fun to make for Saint Patrick's Day, this may just be the recipe for you.
Key Lime Pie Rice Krispie Treats *Recipe By Jasey's Crazy Daisy
6 cups rice krispie cereal  6 Tablespoons butter 2 (10 oz) bags Key Lime Marshmallows, you can find them at Wal-Mart zest of 2 limes 1/2 cup white chocolate chips 1- graham cracker, crushed
Note ~ I use 6 cups cereal to make sure they are extra soft and chewy. Depending on your preference, you may decide to add up to 1 extra cup of cereal. I would mix everything together and decide from there. 
Spray a 9x13-inch pan with cooking spray. Measure 6 cups of rice krispies and set aside. In a large microwave bowl, melt butter, marshmallows, and lime zest together in the microwave. Microwave for 90 seconds, stir, and repeat until mixture is smooth. Add krispies to marshmallow mixture and gently stir until evenly coated. Press mixture into prepared pan. Place white chocolate chips in a ziplock baggie. Place in microwave for 20 seconds. Take out and knead to mix. Repeat until chocolate is melted. Cut off a small piece of the corner of the bag and drizzle over bars with. Sprinkle with crushed graham crackers. I usually place them in the fridge to hurry the process (but if you leave them too long, you will have to let them sit out to soften before cutting). Once chocolate has set, cut into bars and enjoy.
