Tim Tams are an iconic Aussie cookie. It has two chocolate cookies sandwiched together with a rich buttery chocolate filling and the whole thing is dipped in milk chocolate. They are pretty amazing!

A lamington is traditionally a sponge cake dipped in a rich dark chocolate icing and rolled in coconut. This recipe joins the two together. I found this recipe in a Super food idea magazine and I'm keeping it here for safe keeping.

  • ·
    2 x 200g (7 oz) packets of original tim tams
  • ·
    400g (14 oz) chocolae cake mix with icing

    1 1/2 cups coconut

How to Make Aussie Tim Tam Lamington Slice


  1. Pre-heat oven to 180oC/375oF. Grease and line a 20 x 30 cm lamington tin (or a large slice tin 12 x 8 inches).
  2. Using a food processor, blitz the cookies until they almost form a paste. Press the mixture into the base of the tin and pop in the fridge to firm up and then bake for 10 minutes.
  3. To make the topping:
    Beat the cake mix, condensed milk egg and half a cup of coconut together. Spread evenly over the partially cooked base.
  4. Bake for a further 25-30 minutes or until a skewer comes with moist crumbs and the top is JUST firm to the touch.
  5. While the slice is hot, pour the icing over the top and carefully cover, being sure to get to all the edges. Sprinkle with remaining coconut and leave to cool completely in the tin.
  6. When cold, slice into 18 - 20 even portions and enjoy!
