Mix the kōkō (cocoa), huka hāura (brown sugar) and miraka (milk) in to a small bowl until it forms a smooth paste.
Spread out the second piece of dough in to a rectangle. Spread the pē kōkō (cocoa paste) on to it. Knead it gently for a few minutes until it is all mixed through, it should not need more flour.
Place it in a bowl and cover with a tea towel. Rise both of the pieces of dough for 1 ½ hours or until doubled in size.
Oil a loaf tin. My tin is 22 cm long, 9.5 cm wide and 10 cm high.
Once they have risen, take each piece and out roll them out to a 40 cm long rectangle.
Get the loaf tin you are using and make the rectangle 4 cm shorter than the length of the tin. My tin is 22 cm long so I made my rectangles 40 cm long and 18 cm wide. Make the cocoa dough slightly smaller than the plain one.
Place the cocoa flavoured dough on top of the plain one. Now gently roll it up in to a tight roll.
Cut the roll into 8 - 10 pieces of the dough, cutting all the way through. Keep the pieces roughly together as you do this. Cutting them like this enable you to pull the parāoa (bread) apart in to perfect slices once it is baked.
Gently hold the pieces as one log and lower them in to your prepared tin. Cover and allow them to rise for another 45 minutes.
Pre-heat the oven to 170 °C.
Bake for 43 minutes until golden. Rub a little butter on to the freshly baked bread and pull apart or cut those delicious slices you have created! Tau kē - awesome!
To make it even better, serve it warm or toasted with my whipped vanilla butter or chocolate almond butter!
