Lightly butter or spray your muffin pan. Then, use a large circle cookie cutter (or you can do this with a knife or kitchen shears) to cut the crescent rolls into circles and line the pan cups.
In a medium mixing bowl, whisk together the eggs, milk, 1/4 cup cheese, garlic powder, and a little salt and pepper. Pour this batter into the prepared baking cups.
Top with the remaining cheese. Bake at 350°F for 20-22 minutes, until the edges of the crust are golden brown.
