📝 Ingredients

For the Base

1 packet (approx. 200 g) Marie biscuits, crushed
100 g unsalted butter, melted

For the Lemon Filling

1 tin (397 g) sweetened condensed milk
½ cup freshly squeezed lemon juice
1 tbsp finely grated lemon zest

Optional Topping

Extra crushed biscuits or desiccated coconut

👩‍🍳 Instructions

Step 1 – Prepare the Pan

Line an 8×8 inch (20×20 cm) square pan with parchment paper, leaving extra on the sides to lift the slice out easily later.

Step 2 – Make the Biscuit Base

In a bowl, mix together the crushed Marie biscuits and melted butter until the mixture resembles wet sand.
Press it firmly into the bottom of the pan using the back of a spoon.
Refrigerate while preparing the filling.

Step 3 – Mix the Lemon Filling

In a clean bowl, whisk together:

sweetened condensed milk
lemon juice
lemon zest

The acidity from the lemon will instantly thicken the mixture into a luscious, creamy filling.

Step 4 – Assemble the Slice

Pour the lemon mixture over the chilled biscuit base and smooth the top.
If you like extra crunch or flavor, sprinkle with more crushed biscuits or desiccated coconut.

Step 5 – Chill and Set

Refrigerate for at least 4 hours, or overnight for best results.
Once firm, lift out of the pan and slice into 12 neat bars.

💡 Tips for the Perfect Lemon Slice

Use fresh lemons — bottled juice won’t give the same flavor or thickness.
Crush biscuits finely for a firm base, or leave a few chunks for texture.
Want a thicker filling? Add an extra tablespoon of lemon juice.
For a firmer bar, freeze for 30 minutes before slicing.

🍋 How to Serve It

With a cup of tea or coffee
As a picnic dessert
On a summer platter with fresh fruit
At baby showers, birthdays, or afternoon gatherings

It also freezes beautifully, making it a great treat to keep on hand!
