Begin by combining whole wheat flour, oat flour, and salt in a bowl, setting the mixture aside.
Warm the milk in the microwave for 25-30 seconds until it reaches a gentle warmth.
In the lukewarm milk, blend dry yeast, then incorporate it into the flour mixture. Stir well, adding the sweetener, applesauce, and whisked egg.
Knead the dough, either using a stand mixer or your hands, but be cautious not to overwork it; about 5 minutes of kneading is sufficient.
Transfer the kneaded dough into a bowl, cover it, and allow it to rise for an hour at room temperature.
Prepare the filling. Soak dates in hot water for 30 minutes. Take the dates out from the water and blend them with cinnamon into a smooth paste.
Once the dough has doubled in size, turn it out onto a floured or greased surface, rolling it into a large rectangle. Evenly spread the delectable date-cinnamon filling over the dough, then roll it up.
Slice the rolled dough into equal pieces using a sharp knife or dental floss.
Arrange the individual rolls in a greased baking pan, letting them proof for another 45 minutes.
In the meantime, prepare the glaze by mixing the powdered sugar and milk.
Brush the rolls with milk before baking at 350F (180C) for 20-25 minutes or until a delightful golden brown appears.
While still warm, generously drizzle the glaze on top of the cinnamon rolls. Enjoy!
