Continue cooking over medium heat. Again, you want the broth to thicken.
Add the rest of the heavy whipping cream. Continue cooking.
Add the remaining chicken broth and cook until the mixture is slightly thick. You don't want it runny, but you don't want it too thick either as it will continue to thicken in the oven.
While the pot pie mixture is thickening, make your drop biscuit dough. You can use any recipe you like for this. I used a combination of water, milk and Jiffy baking mix. An alternative crust is easily made with puff pastry dough. Simply roll the dough out and then use one of the pie pans to cut the dough to size by pressing the pie pan into the dough.
Once the chicken, vegetable and broth mixture is thick enough to suit you, fill each small pie pan about 3/4 of the way full and top with either Jiffy baking mix or pre-cut puff pastry dough.
Drop spoonfuls of the drop biscuit mixture or lay the puff pastry dough on top of the chicken, vegetable and broth mixture. The Jiffy mixture will sink - do not worry about this.
Place the baking dish into the oven and bake at 350 degrees F for 25 to 30 minutes. The crust will turn golden brown when it is done.
When you remove the mini pot pies from the oven allow them to sit for 10 minutes to cool slightly before serving.
