Preheat Oven: Preheat your oven to 350°F (175°C). Generously grease a 10–12 cup Bundt pan with nonstick spray or butter.

Cook the Sausage: In a skillet over medium heat, cook sausage until browned and cooked through. Drain and set aside to cool slightly.

Mix the Egg Filling: In a medium bowl, whisk together eggs, milk, garlic powder, and pepper.

Assemble the Bundt: In a large bowl, gently toss biscuit pieces with sausage and cheese. Pour in the egg mixture and stir to coat everything evenly.

Fill the Pan: Spoon the mixture evenly into the prepared Bundt pan, pressing down lightly to eliminate gaps.

Bake: Bake for 40–45 minutes, or until golden brown and set in the center. If the top browns too quickly, cover loosely with foil in the last 10 minutes.

Cool and Serve: Let rest for 10 minutes, then invert onto a serving plate. Sprinkle with chives or green onions if desired. Slice and serve warm.
