Preheat the oven to 400 degrees and fill the sections of a muffin tin with cupcake liners.
Brown the breakfast sausage completely in a skillet and drain the excess grease.
Add the almond flour, greek yogurt, green onions, baking powder, butter, oil, cheese, garlic powder, the cooked sausage and salt and pepper to taste in a mixing bowl. Blend until well combined.
Add the batter to the cupcake liners to fill them ⅓ of the way full.
Press a hard boiled egg into each section of the muffin tin.
Cover the hard boiled eggs with the remaining batter, covering them completely.
Bake for 20-25 minutes until browned and cooked through.
Let the muffins cool completely before trying to remove them from the cupcake liners.
