Made with just a handful of ingredients you may already have, we turn store-bought lamingtons into your new favourite Aussie summer dessert.

You’ll need a 19cm square cake pan, and you’ll need to start this recipe at least 6 hours ahead.

30 store-bought lamington fingers (you’ll need 2 x 350g packets)
600ml thickened cream
395g can sweetened condensed milk
2/3 cup (220g) raspberry jam
2 tsp lemon juice

Method

1.

Grease a 19cm square cake pan and line base and sides with baking paper. Arrange 15 lamington fingers side by side in base of pan in a single layer.
2.

In a stand mixer fitted with the whisk attachment, beat cream and condensed milk on medium speed until soft peaks form. Pour two-thirds of the cream mixture over the lamington fingers (see recipe notes). Mix the jam and juice in a small bowl until combined. Dollop jam mixture over cream and use a butter knife to swirl through the cream mixture. Arrange remaining lamington fingers on top, making sure to match the pattern of the bottom layer of lamington fingers (see recipe notes). Slightly push the top lamington fingers into the cream mixture. Cover with plastic wrap and freeze for 6 hours, or overnight, until firm.
3.

Unmould onto a chopping board and cut into small sandwiches. Serve immediately.

Recipe Notes

Making sure the fingers are arranged in the same pattern for both layers means that the sandwiches will be easy to cut.

Spoon remaining cream mixture into a small container and cover with plastic wrap, ensuring the plastic wrap is touching the surface of the cream. Freeze for a quick vanilla ice cream treat.

You could also swirl through some chocolate sauce for an added layer of decadence.
