Heat oven to 400°F. Line a rimmed baking sheet with parchment or lightly oil it.
Stir pancake mix, pepper, and garlic powder in a large bowl to combine.
Add sausage and cheddar. Use clean hands to work the mixture until crumbly and evenly mixed.
Pour in buttermilk and maple syrup. Mix just until a soft, cohesive dough forms. Fold in scallions.
Scoop tablespoon portions and roll into balls. Arrange on the prepared sheet, spacing slightly.
Bake 16–18 minutes until golden and the centers reach 160°F. Rest 3 minutes before serving.
