In a large sauce pan, melt butter over low heat. Once butter has melted, stir in 8 cups marshmallows. Continue cooking over low heat, stirring constantly, until marshmallows and butter are fully melted together.

Remove from heat and stir the lime zest and juice from 4 key limes (approximately 1 1/2 tablespoons juice and 2 teaspoons of zest) into melted marshmallow mixture. Stir cereal/graham cracker mixture and remaining 2 cups of marshmallows into melted marshmallows mixture, stirring until well combined.

About this Recipe
Craving a nostalgic treat with a vibrant, zesty twist? These Key Lime Pie Rice Krispie Treats bring together the classic sticky-gooey texture you love with the refreshing tartness of key lime pie.
What sets these treats apart is the delightful balance of sweet marshmallow and the bright, tangy key lime juice and zest. The addition of chopped graham crackers also adds a wonderful textural element, mimicking a pie crust, making each bite an exciting combination of familiar comfort and tropical zest.
Prepare for a symphony of textures and flavors. Each bite delivers that familiar chewy goodness of a perfectly made Rice Krispie Treat, followed by a burst of authentic tart key lime that cuts through the sweetness beautifully. The creamy white chocolate drizzle, with a hint of coconut oil for gloss, adds an extra layer of indulgence, making these treats feel truly special and gourmet. They're surprisingly simple to make, perfect for satisfying a sweet craving without much fuss, offering a delightful and unique dessert experience.
While the key lime flavor is central, you can adjust the amount of key lime juice and zest to your preference for more or less tang. If you're out of white chocolate, the recipe notes that vanilla almond bark works just as well for the drizzle. You can also skip the white chocolate drizzle entirely for a purer key lime flavor, or if you prefer a less sweet treat.
These sticky and gooey treats are perfect for potlucks, parties, or as a fun, quick dessert after any meal. They make a colorful, refreshing addition to any dessert platter, especially when garnished with a little extra key lime zest.
