Melt 1 tablespoon butter in large skillet. Cook beef until no longer pink and cooked through. Remove from skillet and set aside.
In the same skillet, wipe clean. Then melt remaining butter. Add mushrooms and cook over medium heat for 7-8 minutes.
Stir in Madeira and cook for 2 minutes. Add cream and bring to a boil. Reduce heat and cook until thickened about 5-6 minutes.
Add in frozen peas and beef broth. Cook on low for 5 minutes.
Add in cooked beef. If the consistency needs to be thickened - add 1 tablespoon cornstarch mixed with 1 tablespoon water.*
Roll out pie crust on flat surface. Take each ramekin and cut out circle around it to fit on top.
Spray each ramekin with cooking spray. Add in pot pie mixture until almost to the top. Repeat with each ramekin and top with pie crust. Crimp each dough piece on top of each ramekin to secure it.
Place ramekins in oven and bake for 11-14 minutes.
Notes
*If you add the cornstarch and it becomes too thick, you can add a little beef broth to thin it out (no more than 1/4 cup).
