Preheat the oven to 350 degrees. Boil the potatoes in salted water for 15 minutes, or until tender. Drain, place on a sheet pan, and bake at 350 degrees for 10 minutes. Remove the potatoes from the oven and transfer to a large bowl. Add the butter to the bowl and mix with an electric mixer until smooth. Add the cream until it reaches the desired consistency. Stir in the poblanos and season to taste with salt and pepper.
