Add the tiakarete (chocolate), pata (butter) and tote (salt) in to a small pot and melt gently over low heat. Remove from the heat and cool for 5 minutes.
Whip the hēki (eggs), huka one (caster sugar) and wanira (vanilla) for 3 minutes until light in colour and fluffy.
Slowly pour in the cooled ranunga tiakarete (chocolate mixture) as you continue to whip. Once all the tiakarete (chocolate) is incorporated, stop whipping.
Sift in the kōkō (cocoa), puheu parāoa (flour) and pēkana paura (baking powder). Stir it with a whisk just until it is all incorporated.
Pour it on top of the paparanga pihikete (biscuit layer). Dollop on the remaining tiakarete (chocolate) and pata nati (nut butter).
Sprinkle over the kokonati (coconut) and māngohe (marshmallows).
Bake in a 160 degree oven for 25 minutes. Allow to sit for 10-15 minutes in the tin before slicing in to delicious pieces.
