A quick and simple no-bake lemon tart with a buttery crust and tangy lemon filling, perfect for special occasions like Mother’s Day. Ready in under 20 minutes with just three main ingredients.

Ingredients

Scale
  • 1 ½ cups (150g) crushed digestive biscuits or graham crackers
  • 6 tablespoons (85g) unsalted butter, melted
  • 1 can (14 oz / 400g) sweetened condensed milk
  • ½ cup (120ml) fresh lemon juice (about 34 medium lemons)
  • Optional: lemon zest from 1 lemon

Instructions

  1. Crush 1 ½ cups (150g) of digestive biscuits or graham crackers until they resemble fine crumbs using a food processor or rolling pin.
  2. Transfer crumbs to a mixing bowl and pour in 6 tablespoons (85g) of melted unsalted butter. Stir until mixture looks like wet sand.
  3. Press the crumb mixture firmly and evenly into the bottom and slightly up the sides of a 9-inch (23cm) tart pan or pie dish.
  4. Chill the crust in the refrigerator for about 10 minutes to set.
  5. In a medium bowl, combine the entire 14 oz (400g) can of sweetened condensed milk with ½ cup (120ml) fresh lemon juice and optional lemon zest. Stir gently until the mixture thickens and turns pale yellow.
  6. Pour the lemon filling over the chilled crust and smooth the surface with a spatula.
  7. Refrigerate the tart for at least 3 hours or overnight until the filling is firm and sliceable.
  8. Remove the tart from the pan if using a removable bottom, slice into wedges, and garnish as desired.

Notes

Use fresh lemon juice for best flavor and proper filling set. Chill the tart for at least 3 hours to ensure the filling firms up. For gluten-free crust, substitute digestive biscuits with gluten-free cookie crumbs or ground nuts. For dairy-free/vegan versions, use vegan butter and coconut condensed milk. Crushing biscuits to a mix of fine crumbs and some larger pieces improves crust texture.
