Why This Recipe Works

This recipe relies on the natural reaction between acidic lime juice and sweetened condensed milk, which thickens the filling without requiring extensive baking. Egg yolks add structure and richness, while the short bake time ensures the custard sets without curdling. The coconut graham crust provides a sturdy, flavorful base that complements the creamy filling. Proper chilling allows the pie to firm up fully, creating clean slices and a silky texture. With an estimated 230–300 calories per slice, it delivers indulgence while remaining relatively balanced for a dessert.

It’s easy to prepare, perfect for make-ahead occasions, and adaptable to your taste preferences.
