In a bowl add yeast in lukewarm soy milk and let the yeast dissolve. The add egg, oil, spices, sugar and mix together.
Add all of the kamut flour and mix it into the dough. Now add a little white all purpose flour at the time until you reach a perfect dough. Knead the dough for a couple of minutes. Place it back in the bowl, cover it with a cloth and let it sit for 1-1 ½ hour, preferable a warm place.
Make the date-remonce by mashing and mixing the dates, coconut oil/butter and honey well together using a fork.
On a big flour covered surface, role out the dough into a rectangular shape about 1/2-1 cm thick. Spread all of date-remonce on to the dough, in an even layer. Then cover the surface with thinly sliced apple boats (very thin), and top with grated marzipan and 2 Tbsp cinnamon. Starting at long side, tightly roll up. Use a knife to cut it out into 16-18 pieces (2-3 cm thickness).
Line your baking pan with parchment paper and place all of the buns together, it is okay that they touch each other. Heat the oven to 375 F °/175 C °. In the mean time let the buns rise for 30 min and afterwards bake them in the oven for 15-17 min.
While the buns are baking, you can make the chocolate frosting. You simply heat the milk in a pot and when close to boiling you add the chocolate little of the time until it is thick and creamy. Let cool a bit and add to the cake when it is done and have cooled down.
