When asked to “bring a plate”, I often lean towards creating a sweet treat. Rocky road is usually my “go to” sweet, and is generally well received, but on other occasions I like to bring a plate of lemon slice. For it is easy to make, requires no baking, and the leftovers keep really well too.
Recently I offered to make a couple slices for a birthday party. I had a few chocolate based ones in mind, and figured my favourite lemon slice would work beautifully as a nice flavour contrast to those. And with some lemons leftover from the peach and lemon cake, well it was a no-brainer really.
So one dreary morning, my helpers and I got to work. Lemons were juiced and zested, biscuits were crumbed and condensed milk and butter were heated. And before too long we had ourselves a big tray of lemon slice, sprinkled with coconut, and ready to be sliced and served.
This was a great slice to make with the kids too. They had a lot of fun turning the food processor on and off, and stirring the coconut and melted ingredients into the biscuit crumbs. Bowls and spoons were licked not long after, and coconut was liberally sprinkled over the iced slice (and most of the kitchen benchtop, but let’s not talk about that…!)

- Process the biscuits in a food processor until they resemble fine breadcrumbs. Place in a large bowl, add the coconut, lemon juice and zest, and stir to combine.
- Place the sweetened condensed milk and butter in a saucepan. Heat slowly, over a low heat, stirring until the butter has melted.
- Pour the butter mixture into the biscuit mixture, and stir until well combined. Press firmly into a slice tin (that is lined with baking paper), and place in the fridge for 10 minutes.
- Place the icing sugar and extra lemon juice in a small saucepan. Heat gently, stirring, until the sugar has melted and the ingredients have combined. Spread over the chilled slice, and sprinkle with extra coconut. Refrigerate for a couple of hours (or overnight) then slice and serve.
