Twice Baked Potato Casserole

I was so blessed to have a house full of family for Easter dinner.  We had a great time and we all filled our bellies with really good food!  We had ham, twice baked potato casserole, salad, roasted asparagus, roasted Brussels sprouts, strawberry pretzel salad, and 2 pies and a cheese cake.  We ate like kings!!
This was the only decent picture I could get of this dish.  It was nearly devoured the first pass through the food line. 
I love to eat twice baked potatoes.  But I had to start switching it up after we had 20 guests for Christmas.  That is a very time intensive dish for that many people.  So, I went ahead and made it as a casserole and it was fabulous.  My aunt made a version of this dish for us for Christmas and it too was devoured.
There is not really a recipe.  I made mashed potatoes using about 8 oz of cream cheese, 2 cups sour cream, garlic powder, butter, salt and pepper.  I layered half the potatoes in a deep 9x13 lasagna pan, then I topped that with 2 cups 3 cheese mix and crumbled bacon.  Then do the layers again and bake for about 30 minutes at 350 until it is hot all the way through.  Oh man alive!!  It was tasty.  I call it 1000 calorie potatoes.  It is definitely just a holiday dish.
