Process
Preheat the oven to 170° C and line a baking tin with parchment. Grease the pan and parchment with butter or a little oil and dust sparingly with flour.
Sift the flour and baking soda and set aside.
Cream the eggs and sugar until light, fluffy and pale in a stand-mixer or with a whisk.
Heat the milk with the butter gently in a thick bottomed pan and then add the cream of tartar, stir and leave to cool slightly.
Fold in the milk and flour mixtures alternatively into the eggs and sugar until just combined with a splash of vanilla.
Pour into the prepared baking tin and bake for 25-30 minutes.
Once baked, allow to cool in the tin.
For the chocolate dipping sauce, combine the sauce ingredients (except the coconut…save that for the assembly later) in a thick bottomed pan and heat through gently until syrupy and thick. Once cooked, allow to cool.
To assemble…
Nearly there…Assemble the lamingtons by cutting the cake into squares and then dipping each square into the chocolate dipping sauce. Coat each side of the square with coconut and viola! The delectable lamington.
