01 - Preheat oven to 350°F. Grease a bundt pan or deep round baking dish thoroughly with butter or oil.
02 - In a large mixing bowl, combine almond flour, protein powder, baking powder, and salt. Whisk together until evenly blended.
03 - In a separate bowl, whisk Greek yogurt, eggs, almond milk, melted coconut oil, and vanilla extract until completely smooth and well combined.

06 - Pinch off small portions of dough, about 1 inch in size. Roll each piece into a ball, dip in melted butter or coconut oil, then coat completely in the cinnamon mixture.
07 - Place coated dough balls in the prepared pan, layering them evenly. Leave slight space between pieces to allow for expansion during baking.
