Prepare Dough: In a small bowl, mix oat flour, True Nutrition Cinnamon Bun Whey Protein Powder, baking powder, and cinnamon. In another bowl, whisk together melted coconut oil, egg white, almond milk, vanilla extract, and sweetener (if using).
Combine Wet and Dry Ingredients: Pour the wet ingredients into the dry mixture and stir until a soft dough forms.
Roll and Add Filling: On a clean surface, sprinkle a bit of oat flour and roll the dough out into a small rectangle. Brush with melted coconut oil and sprinkle the cinnamon and sweetener mixture for the filling.
Roll the Dough: Gently roll the dough into a cinnamon roll shape and place it in a small, greased ramekin or muffin tin.
Bake: Bake for 12-15 minutes or until golden brown and firm.
Make the Icing: While the cinnamon roll is baking, whisk together the yogurt, vanilla, sweetener, and almond milk to create the sugar-free icing.
Drizzle and Serve: Once the cinnamon roll is baked, drizzle the sugar-free icing on top, and enjoy!
