Place steaks into slow cooker
Add chunky quarter cut mushrooms on top of steak
Whisk beef stock into cooking cream and pour over the steak and mushrooms
Cook on low for 5hrs
30mins prior to serving carefully remove steaks onto serving plate (I used 2 egg flips to do so while still keeping them intact),
Combine cornflour and water and whisk into the mushroom sauce
Gently return steaks to the sauce, place tea towel under lid and turn to HIGH for last 30mins to thicken sauce.
Gently lift steaks out onto serving plate and top with lots of the lush creamy mushroom sauce.
The steak is fall apart, melt in your mouth tender... 2 -4 - 6 - 8 dig in don't wait!
