Preheat your oven to 375°F (190°C).
Take oil or melted butter and grease a 9×13-inch baking dish, making sure to coat the bottom evenly. (I always use oil)
Arrange the chicken in a single layer over the butter in the baking dish.
Spread the frozen peas and carrots evenly over the chicken. (Don't stir)
In a separate bowl, whisk together the cream of chicken soup, chicken broth, and seasonings until smooth and well combined.
Pour this mixture over the chicken and veggies, making sure it spreads across the whole dish without mixing it in, don't stir.
In another bowl, mix the Cheddar Bay Biscuit Mix (set aside the seasoning packet for later), whole milk, and shredded cheddar cheese.
Gently pour the biscuit batter over the chicken and veggies, spreading it out without stirring.
Bake the cobbler in the oven for 55-65 minutes, or until the biscuit topping is golden and fully cooked. The center may still seem slightly runny, but it will thicken up as it cools.
While it’s baking, melt 2 tablespoons of butter in a microwave-safe dish.
Stir in the seasoning packet from the Cheddar Bay Biscuit Mix.
Once the cobbler is done baking, brush the seasoned butter over the top of the biscuits for extra flavor.
Let the cobbler sit for 10-15 minutes after it comes out of the oven to allow the sauce to thicken before serving.
