Heat the oven to 325°F. Pull the steaks out of the fridge and let them come to room temperature. Line a baking sheet with foil.
In a medium bowl, whisk together the dry rub ingredients. Pat the steaks dry and season liberally with salt. Lay each steak in the bowl of dry rub, thoroughly coating both sides and all the edges with the mixture.
Heat a large saute pan over medium high heat and add the olive oil. When hot, sear the steaks for 5 minutes without moving them, until slightly charred on one side. Flip the steaks over and sear for another 3 minutes.
Transfer the steaks to the foil-lined sheet, and leave the pan uncleaned (you will use this to make the sauce). Place the sheet in the oven and cook until medium rare (125°F), or to your desired temperature (about 10-20 minutes). Check the temperature after 10 minutes, and then every 5 minutes until done.
When cooked to the desired temperature, remove the tray from the oven and transfer the steaks to a cutting board to rest. Remember that the steak will continue to cook a bit once removed from the oven, so always err on under-cooking the steak rather than over-cooking. You can always through the meat back in the pan if you need to, but you can't do the reverse!
Once the steak has rested, slice it short ways about ¼ inch thick. Fan the cut slices of steak out on half of each plate, drizzling them with the cream sauce. Make sure to include a few peppercorns with each serving. Plate with a side dish of your choice.
