01 - Preheat oven to 350°F. Generously grease a bundt pan or deep round baking dish with butter or cooking spray.
02 - In a large mixing bowl, whisk together almond flour, vanilla protein powder, baking powder, and salt until well combined.
03 - In a separate bowl, whisk Greek yogurt, eggs, almond milk, melted coconut oil, and vanilla extract until smooth and creamy.
04 - Pour wet mixture into dry ingredients. Stir with a spatula until a soft, cohesive dough forms. The dough will be slightly sticky.
05 - In a small bowl, combine erythritol sweetener and ground cinnamon. Mix thoroughly and set aside.
06 - Pinch off approximately 1-inch pieces of dough and roll into balls. Dip each ball into melted butter or coconut oil, then roll generously in the cinnamon-sweetener mixture until fully coated.
07 - Place coated dough balls in the prepared pan, arranging them in layers with slight spacing to allow for rising during baking.
08 - Bake for 25-30 minutes until golden brown on top and set in the center. A toothpick inserted should come out clean.
09 - Let the bread cool in the pan for 10 minutes to allow it to set and become easier to remove.
10 - While bread cools, whisk together Greek yogurt, powdered erythritol, and vanilla extract until smooth. Drizzle glaze over warm bread before serving.
