This no-bake key lime pie is cool, creamy, and bursting with citrus, set in a buttery graham cracker crust. It mixes up in minutes and chills to a silky, sliceable dessert perfect for make-ahead treats.
Pie sets best when chilled overnight for clean slices. Keep covered and refrigerate up to 4 days, or freeze (without fresh lime slices) for up to 2 months and thaw in the refrigerator. For neater cuts, wipe the knife between slices. A paper towel in the storage container can help prevent condensation and keep the crust crisp.
