5 Ingredient Creamy Lemon Slice

The best part about this Creamy Lemon Slice is that it’s made from just 5 ingredients!

  • crushed biscuits – also called cookies in some parts of the world. You can use absolutely any brand of plain sweet biscuits/cookies you like. I generally use Arnott’s Marie biscuits which are very popular in Australia.
  • melted butter – you can use either salted or unsalted butter for this recipe.
  • lemon juice – fresh or store-bought lemon juice can be used for this recipe.
  • sweetened condensed milk – I recommend using full cream sweetened condensed milk (not skim) as it sets firmer when baked and has a creamier texture.
  • eggs – use large eggs (approximately 55g each).

How To Make This Recipe

Step 1 – Make the Crust

Grease and line a slice tray with baking paper and set aside. Crush the biscuits until they are fine crumbs, then add the melted butter and mix to combine. Press the biscuit mixture firmly into the base of the tin. Bake and allow it to cool.

Step 2 – Make the Filling

Beat the sweetened condensed milk, lemon juice and eggs until they’re creamy. Pour the liquid onto the baked crust and bake until it’s set. Allow your lemon slice to cool in the fridge for at least 4 hours.

Sweetened Condensed Milk Lemon Bars

These sweet and tangy lemon squares get their creaminess from sweetened condensed milk.

Sweetened condensed milk is a sweet, sticky, thick and creamy liquid made from cow’s milk. It can be bought from all major supermarkets (and can generally be found either the long-life milk section or the baking aisle).

When the sweetened condensed milk is mixed with the eggs and lemon juice, is creates a thick and creamy lemon filling that sets firm when baked.

Using sweetened condensed milk to make a creamy lemon slice is a really easy alternative to a baked cheesecake slice which uses cream cheese and can be a little trickier to bake.

With this slice you still have the same creamy lemon texture (that you’d get in a cheesecake slice) but without any hassle or fuss!

Recipe Tips & FAQ

How long can the lemon slice be stored for?

One your slice has been baked and cooled completely, store it in an airtight container in the fridge for up to 5 days (if it lasts that long!)

Can you freeze lemon bars?

Yes you can! Simply freeze in an airtight container for up to 3 months. Because this slice is made with sweetened condensed milk, it wont freeze solid, but rather change into a firm texture. Many of our readers love to eat this slice directly from the freezer as a frozen treat during summer!

To defrost the slice, simply place into the fridge for an hour or two.

What type of biscuits should I use?

You can use any biscuits you may have around the house. Digestive biscuits are great (in America, they’re called graham crackers). Otherwise Arnott’s Marie biscuits are perfect too.

How long should I chill my creamy lemon slice in the fridge before eating?

It needs time to fully set, so let it chill for at least four hours. I prefer to leave mine in the fridge overnight.

Can this recipe be doubled?

Absolutely! You will need to use larger slice tin and increase the baking time slightly.
