In a crockpot, add chicken, seasonings, butter, chiles, onion, broth, garlic, and sriracha.
Stir and cook on low for 4-6 hours.
Remove chicken, shred, and return to crockpot
Add cream cheese (I used my bullet blender with some warm broth from the soup to make it creamy, then poured into the crockpot)
Add shredded cheese and heavy cream
Stir and replace lid & let cheese melt
