01 - Preheat oven to 350°F. Grease a bundt pan or deep round baking dish thoroughly with butter or cooking spray.
02 - In a large mixing bowl, whisk together almond flour, vanilla whey protein powder, baking powder, and salt until well blended.
03 - In a separate bowl, whisk Greek yogurt, eggs, almond milk, melted coconut oil, and vanilla extract until smooth and fully incorporated.
04 - Pour wet ingredients into dry mixture. Stir with a spatula until a soft, pliable dough forms. The dough should hold together when pressed.
05 - In a small bowl, combine erythritol and ground cinnamon, mixing until evenly distributed.
06 - Pinch off approximately 1-inch pieces of dough and roll into balls. Dip each ball in melted butter or coconut oil, then roll thoroughly in the cinnamon-sweetener mixture until coated.
07 - Place coated dough balls in the prepared pan, layering them evenly. Leave slight space between pieces for expansion 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 slightly before removing or glazing.
10 - While bread cools, whisk together plain Greek yogurt, powdered erythritol, and vanilla extract until smooth and creamy.
11 - Drizzle glaze over warm bread. Serve immediately while still warm for best texture and flavor.
