Preheat oven to 350 degrees Fahrenheit.

In a saucepan, melt coconut oil over medium heat. Mix in maple syrup and let it start to bubble. Once it bubbles, mix in apples, cinnamon and vanilla. Allow to cook for about five to eight minutes, until apples begin to soften. Mix cornstarch with water until it has dissolved. Add cornstarch mixture to saucepan. Cook for another few minutes until it has thickened. Allow to cool.

In the meantime, on a floured work surface, roll out challah dough into a large rectangle. Sprinkle brown sugar over dough, then spread on cooled apple mixture, then spread on halva and pecans. Sprinkle on maple flakes if desired.

Roll up and then cut in half to form two skinnier rolls with insides exposed. Twist the two rolls together and place into a greased loaf pan.

Bake for about 15 minutes. Remove from oven and brush with caramel. Bake for an additional 20 minutes.
