No-bake key lime pie is a chilled dessert made with a buttery biscuit crust and a tangy, creamy lime filling—set without an oven using refrigeration.
Core idea
Instead of baking, the filling “sets” in the fridge thanks to the reaction between lime juice and sweetened condensed milk, creating a smooth, custard-like texture.
Ingredients
Crust
- Crushed digestive biscuits or graham crackers
- Melted butter
- Optional: a little sugar for sweetness
Filling
- Sweetened condensed milk
- Fresh lime juice (key lime or regular lime)
- Lime zest (for stronger flavor)
- Whipped cream or whipped topping (for lightness)
Optional topping
- Whipped cream
- Lime slices or extra zest
How it’s made
- Make crust: Mix crushed biscuits with melted butter, press into a dish, and chill until firm.
- Mix filling: Whisk condensed milk with lime juice and zest until thickened.
- Lighten it: Fold in whipped cream for a softer texture.
- Assemble: Pour into crust and smooth the top.
- Chill: Refrigerate 4–6 hours (overnight is best).
What makes it special
- Bright, tangy flavor balanced with sweetness
- No oven needed—very beginner-friendly
- Creamy, mousse-like texture when chilled properly
