Coconut Lemon Slice

What is lemon slice?

Don’t quote me, but I think the coconut lemon slice recipe comes from a condensed milk brand. Wherever it comes from it’s become an Aussie classic and possibly around the world too.

It’s a simple mix of butter, condensed milk, biscuits and lemon for the no bake base, which has a fudgy texture. It is normally covered in a layer of simple 3 ingredient lemon icing – icing sugar, butter and lemon juice.

I love the traditional recipe but I was really craving a thick, creamy topping when I made this, so I made a whipped lemon frosting that hit the brief. I’ve included the recipe for both in the recipe card.

How to make coconut lemon slice

1. Start by mixing together condensed milk and butter in a bowl, then microwave that in 30 second bursts, stirring well between each, until it’s smooth. This only takes about 90 seconds.
2. Add biscuit / cookie crumbs, coconut, lemon juice and zest and give it a good mix around. Press it into a lined baking tin.
3. To make the whipped lemon frosting, start by beating together butter and icing sugar until light and fluffy.
4. Now add cream and beat just to combine.
5. Add some melted white chocolate and beat on high for about 3 minutes or until it’s super smooth and looks like whipped cream.
6. Finally mix through some lemon zest, then spread it over the base.
7. Chill for a couple of hours until set then cut and serve.

Cooks tips

• Biscuits: I use a combination of Arnotts Granita and Arnotts Milk Coffee. Anything similar will work including Milk Arrowroot and Graham Crackers.
• Turning them into crumbs: I use a food processor to blitz the biscuits to crumbs. Just note the finer the crumb, the fudgier the base will be.
• Don’t overheat the butter and condensed milk: Just heat it and stir regularly until it’s the butter is melted and it’s combined. You can do this in the microwave or on the stove top.
• The baking tin: I use an 8×8 inch baking tin which gives a very deep base, then cut it into 32 pieces. My sis uses a 9×13 baking tin which makes a thinner base.
• Lemons: You’ll need about 2 lemons for this recipe and that should get you the right amount of lemon juice and zest. Zest them first, then juice them through a strainer to strain out any pips or pulp.
• Topping: I reserve just a little lemon zest and a little coconut to sprinkle on top.

Storage

Lemon slice will keep well in the fridge for 4-5 days (if it lasts that long). Store it in an airtight container.

It can also be frozen, again in an airtight container for up to 2 months. Let it thaw in the fridge overnight or if it’s not terribly hot, you can thaw it on the countertop. If it’s pre-sliced, it should thaw in less than 20 minutes.
