Preheat the oven to 350ºF and line a small baking sheet with parchment paper.
Make the dough: add the flour, blended cottage cheese, maple syrup, and baking powder to a bowl and mix to combine. Once combined, knead the dough into a ball. You’ll know the dough is ready if you poke the dough and it bounces right back.
Lay the dough onto a floured surface and roll it out into a 4x8-inch rectangle (measurements do not have to be exact).
Make the cinnamon filling: in a small bowl, combine the brown sugar, protein powder, and cinnamon.
Spread the brown sugar mixture over the top of the rolled-out dough. Then tightly roll the dough lengthwise into a log.
Cut the cinnamon rolls into 2-inch wide rolls, you should have four rolls. Dip your fingers into water and trace it along the seems of the cinnamon rolls. Then gently pinch to make sure the ends are attached to the roll. This way they won’t unroll while baking.
Transfer the rolls to the lined baking sheet and bake for 20-22 minutes.
Make the frosting: While the rolls are baking, add all the ingredients to a bowl and use an electric mixer to mix the ingredients together. Be sure the cream cheese is softened or you will end up with lumpy frosting.
Before frosting, brush on some melted butter. Then, frost the cinnamon rolls right before serving.* If you’re fancy, sprinkle on some ground cinnamon.
