30-Minute Fluffy Key Lime Pie
A lighter version of the classic Key lime pie that combines tangy Key lime juice with sweetened condensed milk and fat-free whipped topping for a fluffy, cloud-like texture. The graham cracker crust provides a sweet, crunchy contrast to the smooth filling. This refreshing dessert is perfect for summer gatherings or when you want a citrusy treat that's less heavy than traditional versions. The no-bake filling comes together quickly, requiring just a brief chill time to set into perfect slices.
