1 premade graham cracker crumb pie crust (9-inch)

¾ cup lemon juice (freshly squeezed or bottled)

2 cans sweetened condensed milk (14 ounces each)

½ teaspoon vanilla extract

1 teaspoon lemon zest

Directions

1. In a large mixing bowl, combine the sweetened condensed milk and vanilla extract. Whisk until smooth and fully blended.
2. Add the lemon juice and lemon zest to the bowl. Continue whisking for about 1 to 2 minutes. The mixture will begin to thicken as the lemon juice reacts with the condensed milk.
3. Pour the thickened filling into the prepared graham cracker crust.
4. Use a spatula to spread the filling evenly and smooth the top.
5. Place the pie in the refrigerator and chill for at least 4 hours until fully set. For a firmer texture, you may freeze the pie overnight.
6. If frozen, remove the pie from the freezer and allow it to sit at room temperature for about 15 to 20 minutes before slicing.
7. Slice and serve chilled.
