In a large mixing bowl, whisk together the dry ingredients until they are well combined.
Add the Greek yogurt and melted butter to the bowl and mix with a wooden spoon until a loose dough forms.
Lightly flour your hands and gently knead the dough until it starts to hold together.
Move the dough to a lightly floured countertop and continue kneading for an additional two or three minutes. Add more flour as needed to prevent the dough from becoming too sticky.
Once the dough is smooth, shape it into a rectangle and roll it out to about a quarter or eighth of an inch thick.
Gently spread softened butter over the flattened dough, allowing a bit of space around the edges to avoid any spills.
In a small bowl, mix together the sugar and cinnamon for your filling. Evenly sprinkle this mixture over the dough, again leaving some space around the edges.
Carefully roll the protein cinnamon roll, starting on the wide side.
Use a sharp knife to cut the dough into individual rolls, each about 1-2 inches thick.
Lightly grease a 12" skillet with cooking spray or oil. Place your cinnamon rolls in the skillet, standing them upright on their end, and allow them to cook for 15-20 minutes until they're golden brown and cooked through.
Remove the skillet from the heat with oven mitts and allow the cinnamon rolls to cool for a few minutes before drizzling with the Greek yogurt glaze.
To make the glaze, whisk the Greek yogurt and powdered sugar together until smooth.
Notes
This recipe is made using bone broth protein. You can also use whey protein or pea protein powder.You will need to add more flour as you knead the dough so it doesn't get to sticky.
