In a large skillet, melt butter over medium heat. Add carrots, celery, and cook until softened, about 5 minutes.

Stir in flour and cook for 1 minute. Gradually add chicken broth and heavy cream, stirring constantly until thickened.

Add shrimp, scallops, peas, Old Bay seasoning, salt, and pepper. Cook until seafood is cooked through, about 5-7 minutes. Remove from heat.

In a mixing bowl, combine flour, baking powder, garlic powder, and salt. Stir in shredded cheddar cheese.

Add milk and melted butter, mixing until just combined. Do not overmix.

Preheat the oven to 400°F (200°C). Pour the seafood filling into a baking dish.

Drop spoonfuls of the biscuit dough over the seafood filling, covering it evenly.

Bake for 25-30 minutes or until the biscuits are golden brown and cooked through.

Let cool for a few minutes before serving. Enjoy!
