Preheat the oven to 400 F. Separate the biscuit dough into biscuits, and flatten each one slightly. Place a small amount of mac and cheese in each biscuit, and roll it into a ball.
Place the biscuits onto a large greased baking sheet. In a small bowl, combine melted butter, minced garlic, and grated parmesan cheese.
Brush the mixture evenly over the biscuit dough. Bake for 15-20 minutes.
