Prepare ingredients. Cube the cooked chicken, chop the onions, and cut the carrots, setting aside in separate bowls.
In small pot, heat chicken stock and dissolve bouillon cubes. Leave on low heat.
In dutch oven, melt butter and sauté onions over medium heat for 10-15 mins. Add the carrots after about 5-8 minutes.
Add flour and whisk, allowing it to cook for 2 mins.
Next add chicken stock, salt, pepper, and heavy cream. and stir together.
Mix in the cubed chicken, corn, and peas. Mix well and allow to simmer for 5-10 minutes or until filling reaches desired thickness
Add the pot pie filling to the skillet and set aside while making cheddar biscuit topping. The biscuits will absorb some of the filling, so make sure you fill up the skillet most of the way, leaving around ½" for the biscuit dough.
Depending on the size of your skillet, you may have extra filling. It can be served separately as a pot pie soup, or you can always use a bigger skillet or casserole dish to make a larger serving. Recommend a 10-12" skillet.
