Prepare the crust:
Mix biscuit crumbs with melted butter until evenly combined. Press the mixture firmly into a pie dish to form the base and sides. Refrigerate for 20 minutes to set.
Make the filling:
In a bowl, whisk together sweetened condensed milk and fresh lime juice until smooth and slightly thickened.
Add flavor:
Stir in lime zest and finely chopped basil leaves to infuse a fresh herbal aroma.
Fold cream:
Gently fold whipped cream into the mixture to create a light and creamy texture.
Assemble the pie:
Pour the filling over the chilled crust and smooth the surface evenly.
Chill:
Refrigerate the pie for at least 4–5 hours (or overnight) until fully set.
Serve:
Garnish with lime slices or small basil leaves before serving for an elegant finish.
