Pre-heat the oven to 160 °C.
Grease two 19 cm or 20 cm spring form cake tins with butter. Add baking paper to the base with a large over hang on the outside of the tin.
Add teiti (dates), wai wera (hot water) and tote (salt) in to a pot or a medium sized microwave proof bowl. If you are using the stove, bring the mixture to a boil and boil on high for 6 minutes. If you are using the microwave, heat on high for 4 minutes.
Remove from the heat and mash the dates until a smooth paste forms. Leave it to cool slightly. Add the pata kūteretere (softened butter), huka hāura (brown sugar) and iho hūperei (vanilla essence) to a large bowl. Whip on high for five minutes until the butter has changed to a light pale colour.
Add an egg at a time and beat for 15 seconds after each addition. Don't worry if it looks a bit split after the third hēki (egg), it will all come back together. Add the kōkō (cocoa), raukikini whakauruuru (mixed spice) and hinamona (cinnamon) in to the butter mixture. Mix well.
Stir the miraka (milk) in to the slightly cooled date mixture. Add it to the butter mixture. Fold it through.
Add the puehu parāoa whakatipu (self-raising flour). Fold it all together. Divide the mixture between the two cake tins. Spread ⅓ C of the caramel sauce on top the top of each of the cakes. The remaining caramel sauce will be used for decorating. Bake for 40 minutes until they spring back in the middle when pressed.
Once the cakes have finished baking, remove from the oven and allow them cool in the tins for 5 minutes before flipping them out. Cool completely before decorating.
