This no-bake lemon slice is the easiest sweet treat you'll ever make! Going down a treat in school lunch boxes (when we get unlocked, of course) or as an afternoon snack, this zingy, zesty bite is a winner.

1. Spray a 32 x 18 x 3cm Swiss roll tin with non-stick spray; line with baking paper.

2. Use a processor to crush biscuits to fine crumbs, or place in a plastic bag and bash with a rolling pin. Mix in coconut, zest and juice; stir or pulse to combine.

3. Melt butter and add the condensed milk, then stir into biscuit mixture till thoroughly mixed. Press into the prepared pan. Cover with another piece of non-stick baking paper and use a can from your pantry to smooth and compact the mixture. Place in the freezer for 20 min to firm. Make the icing.

4. Pour on the icing and spread with a spatula. Place in the fridge to set.

Place icing sugar in a bowl, add lemon juice to taste and just enough water to make a spreadable consistency.

Enjoy!
