Preheat the oven to 350℉ and spray a 6-count muffin tin with cooking spray. Set aside.
Make the dough. Begin by blending the cottage cheese until smooth. Then add the blended cottage cheese, PB2, and maple syrup into a large bowl and stir to combine. Make sure there are no lumps.
Add the flour, baking powder, sea salt, and chocolate chips to the PB2 mixture. Use a silicone spatula or wooden spoon to combine.
Once a ball has mostly formed, turn the dough out onto a lightly floured surface. Roll the dough into a rectangle about 6x10 inches.
Make the filling. Mix together the brown sugar, PB2, and cinnamon in a small bowl. Spread it on top of the rolled-out dough. Then tightly roll the dough lengthwise into a log.
Cut into 6 pieces and place in the muffin tin.
Bake for 15-18 minutes or until a toothpick inserted into the center comes out clean. Cool for 10 minutes.
While the rolls are baking, make the frosting. Add all of the frosting ingredients to a bowl and whisk to combine.
Frost the cooled cinnamon rolls and serve.
