Gently warm the milk to 110°F (lukewarm bath temp.). You can microwave the milk for about 1 minute and 10-15 seconds to do so. Pour milk into a large bowl with the yeast and 2 teaspoons of sugar. Stir and let sit until bubbles form and yeast is activated.
Stir in remaining sugar, eggs, salt and melted butter.
Add the flour and mix using the beater blade just until the ingredients are barely combined. Allow the mixture to rest for 5 minutes so the flour has time to soak up the liquids.
Scrape the dough off the beater blade and remove it. Attach the dough hook.
Beat the dough on medium speed for 5-7 minutes or until the dough is elastic and smooth. **The dough will be tacky and will still be sticking to the sides of the bowl. That’s ok! Don’t be tempted to add more flour at this point.
Spray a large bowl with cooking spray.
Use a rubber spatula to remove the dough from the mixer bowl and place it in the greased large bowl. Cover the bowl with a towel or plastic wrap.
Set the bowl in a warm place and allow the dough to rise until doubled in size, about 1 hour.
While the dough is rising, prepare the cinnamon filling. In a medium bowl, combine the tahini, crème fraîche, brown sugar and cinnamon, mixing until well combined. Set aside.
Sprinkle a pastry mat generously with flour. Turn out the dough onto the pastry mat and sprinkle the top of the dough with additional flour.
Flour a rolling pin and roll the dough to about a very large rectangle (about 26″x18″ if you can get it that big).
Use a rubber spatula to smooth the cinnamon filling over the whole dough rectangle.
Use a pizza cutter to cut the rectangle in half lengthwise. Then, cut 1" strips in the opposite direction. You should end up with about 40-48 strips.
Roll up each strip into a small roll, jelly roll style and place the rolls in 2 greased 9×13 baking pans.
Cover the pan and allow the rolls to rise for 20 minutes or until nearly double in size.
While rolls are rising, preheat the oven to 350°F.
Warm the heavy cream until the chill is off. Don’t make it too hot…you just don’t want it cold. It should be warm to the touch.
Once the rolls have risen, pour the heavy cream over the top of the rolls, allowing it to soak down in and around the rolls.
Bake 2 trays on top shelf of oven for about 20-25 minutes, until the rolls are lightly golden brown and the center rolls are cooked through. If the rolls are getting too browned on top, cover loosely with a piece of foil.
