Creating Easy and Zesty Key Lime Truffles is straightforward. Follow these steps to bring your delicious treats to life:

1. Prepare the Mixture: In a mixing bowl, combine the softened cream cheese, powdered sugar, key lime juice, lime zest, and vanilla extract. Mix until the ingredients are well blended and smooth.
2. Chill the Mixture: Cover the bowl with plastic wrap and refrigerate the mixture for about 1 hour, or until it is firm enough to handle.
3. Form the Truffles: Once chilled, use a small cookie scoop or your hands to form the mixture into bite-sized balls. Place them on a parchment-lined baking sheet.
4. Prepare the Chocolate Coating: In a microwave-safe bowl, combine the semi-sweet chocolate chips and coconut oil (if using). Heat in the microwave in 30-second intervals until melted and smooth, stirring between each interval.
5. Coat the Truffles: Dip each chilled truffle into the melted chocolate, ensuring they are fully coated. Use a fork to lift them out, allowing any excess chocolate to drip off.
6. Roll in Graham Cracker Crumbs: While the chocolate coating is still wet, roll the truffles in graham cracker crumbs for an added crunch and a nod to key lime pie.
7. Chill Again: Place the coated truffles back on the parchment-lined sheet and refrigerate them for another 30 minutes to set the chocolate.
8. Serve: Once set, your Easy and Zesty Key Lime Truffles are ready to be enjoyed!
