Melt butter and cream cheese in microwave-safe measuring cup on 30 second intervals until loose and starting to blend; will be lumpy (stir between intervals)
Spray a casserole dish (2.8 L Corning ware) with nonstick spray or butter**
Mix corn, melted butter/cream cheese mixture and about ½ bag of shredded cheese, seasoning with salt and pepper until well mixed (optional add some sliced jalapenos into mixture)
Smooth mixture evenly into dish and spread remaining shredded cheese on top, covering dish with cheese
Dust with more pepper
Optional: Top with a few scattered sliced jalapenos
Note: You can stop here, and cover dish at this point, store in fridge and bake next day
When ready to bake: Preheat oven to 350 degrees
Bake at 350 for 30 minutes or until hot and bubbly
Turn broiler on low and broil for 2-3 minutes more to brown cheese on top (this is a must!)
Remove from oven and let rest 5 minutes before serving
*Don’t use fire roasted corn, the black on the corn will color the cream cheese black and it will not look right…I learned from my mistakes LOL
**For 13x9 dish, increase to 3 bags of corn, full stick of butter plus extra if needed, 1.5 blocks of cream cheese and add ¼ cup more shredded cheese
